In this paper, in order to provide guidance on the design and operation of waste heat recovery heat exchangers for the dryer exhaust of lignite pre-drying, pressure drop and heat transfer characteristics of wet air with ash particles across circular finned tube bundles were experimentally studied under different conditions. The experimental water vapor mass fraction ranged from 5% to 15%, ash particle concentration ranged from 0 to 12.8 g/m3 and mainstream flow velocity ranged from 1.73 m/s to 3.46 m/s, respectively. The pressure drop coefficient generally increases and Nusselt number decreases with time due to the gradual ash deposition. The pressure drop coefficient is sensitive to ash particle concentration, while Nusselt number is sensitive to water vapor mass fraction. Especially, Nusselt number for the ash particle concentration of 1.5 − 5.4 g/m3 is a bit larger than that for the wet air without ash particles. Based on the experimental data, a normalized empirical formula was proposed to calculate the heat transfer characteristics of wet air with ash particles across circular finned tube bundles, and the deviation between experimental data and predicted results is −16.5% to +27.0% for more than 90% of the data.

In this paper, a model was developed to predict the heat transfer characteristics of Marangoni dropwise condensation. In accordance with the feature of Marangoni condensation, condensation was treated as dropwise condensation of mixture vapors. The condensation space was divided into two parts: the vapor diffusion layer and the condensate layer. For the condensate layer, the classical heat transfer calculation method of dropwise condensation was imitated to obtain the heat transfer characteristics. For the vapor diffusion layer, the heat transfer characteristics were achieved by solving the conservation equations. These heat transfer characteristics were coupled through the conjunct boundary, which was the vapor-liquid interface. The model was applied to the condensation of water-ethanol mixture vapors. A comparison with the existing experimental data showed that the developed model could basically reflect the influences of vapor-to-surface temperature difference, vapor concentration, vapor pressure, and vapor velocity on heat transfer characteristic of Marangoni condensation. Results showed that some differences existed between the calculation results and experimental results, but the prediction deviation of the model could be acceptable in the range of vapor-to-surface temperature difference where the condensation heat transfer coefficients reached peak values.

In northern China, many thermal power plants use absorption heat pump to recover low-grade heat from turbine exhaust steam due to the irreplaceable advantages of the absorption heat pump in waste heat recovery. In the process of designing a waste heat recovery system, few researchers have considered the relationship between the design power of the heat pump and the actual heating load of the heating network. Based on the heating load characteristics, this paper puts forward a design idea which uses an absorption heat pump to recover waste heat from a steam turbine exhaust for heating supply. The operation mode of the system for different design powers of the heat pump was stated. An economic analysis model of the waste heat recovery system was proposed, and the optimal design power of the heat pump could be obtained. For a specific unit, the corresponding waste heat recovery system was designed, and various factors affecting the economy of the system were discussed and analyzed in detail.

Marangoni condensation is formed due to the surface tension gradient caused by the local temperature or concentration gradient on the condensate surface; thus, the investigation of the surface temperature distribution characteristics is crucial to reveal the condensation mechanism and heat transfer characteristics. Few studies have been conducted on the temperature distribution of the condensate surface. In this study, thermal infrared images were used to measure the temperature distributions of the condensate surface during Marangoni condensation for ethanol–water mixture vapor. The results showed that the surface temperature distribution of the single droplet was uneven, and a large temperature gradient, approximately 15.6 °C/mm, existed at the edge of the condensate droplets. The maximum temperature difference on the droplet surface reached up to 8 °C. During the condensation process, the average surface temperature of a single droplet firstly increased rapidly and then slowly until it approached a certain temperature, whereas that of the condensate surface increased rapidly at the beginning and then changed periodically in a cosine-like curve. The present results will be used to obtain local heat flux and heat transfer coefficients on the condensing surface, and to further establish the relationship between heat transfer and temperature distribution characteristics.

Melt drop collision is an important phenomenon in the circumstance of pressure wave propagation during fuel–coolant interaction (FCI). The deformation and fragmentation of melt drops can increase the contact area with coolant, and as a result will affect the heat transfer and melt oxidation. In this study, a numerical model was established by considering surface tension and validated with the experimental results that were obtained from water droplet collision in gaseous environment. Then, the head-on collision of two UO2 melt drops in water pool was investigated at different Weber numbers, and the melt morphology, contact area, and the number and size distribution of children droplets were analyzed. The results show that interfacial waves and wrinkles could be clearly observed on the melt film, and the finger structures presented at the rim of melt film and finally separated into children melt droplets. The increase of fuel–coolant contact area could be divided into the inducements by deformation and fragmentation. The melt deformation only had influence to the area increase at intermediate process but no effect to that at steady state. By contrast, the final fuel–coolant contact area was determined by the intensity of melt fragmentation. The size distribution of melt children droplets was like an off-centered normal distribution, where the maximum number of children droplets existed in the size range of 0.03 < D/D0 < 0.045, but the droplets in this size range contributed little to the fuel–coolant contact area. With the above analysis, an empirical model to calculate the contact area was developed. The model had a discrepancy of ±10% in the range of Wec = 290–1815 that the model was established in, but the discrepancies were about 13.3% and 19.3% for the cases of Wec at 2196 and 2612, respectively.

As the evaluation of distributed energy system (DES) is a complex problem, multi-criteria is necessary to fully evaluate the performance for different systems. In this paper, a novel multi-criteria evaluation method was established to assess the comprehensive performance of DES from economic, energy and environment criterions. Before constructing a multi-level indexes system, index correlation analysis was carried out to ensure the independence of indexes. Considering the advantages and disadvantages of subjective and objective methods, AHP-entropy method was proposed by integrating analytic hierarchy process (AHP) and information entropy method together to assign weights to the indexes. Finally, the technique for order preference by similarity to ideal solution (TOPSIS) method was applied to determine the optimal DES scheme. The case study indicated that the evaluation results of this method were in accordance with the reality, which could provide a reference for the selection of DES solutions.

Lignite drying is an effective way of clean and efficient use of lignite. In the waste heat recovery processes of dryer exhausts, ash particles widely exist. In order to provide a reference for the designation of waste heat recovery heat exchangers of dryer exhausts, air/water vapor mixture with ash particles was used to simulate actual dryer exhausts in this paper, and its convection–condensation heat transfer characteristics along horizontal tube bundles were experimentally investigated under various conditions. The effects of concentration of ash particles, water vapor mass fraction, mainstream velocity and temperature were discussed. In the presented experimental conditions, as the convection–condensation proceeded, the convection–condensation heat transfer coefficients of air/water vapor mixture with ash particles reduced and then gradually became stable due to the ash deposition. It was found that the convection–condensation heat transfer coefficients increased with the increase in the water vapor mass fraction and the mainstream velocity, and decreased with the increase in the concentration of ash particles and the mainstream temperature. As the concentration of ash particles increased from 0 to 6.5 g/m3, the convection–condensation heat transfer coefficient decreased from 339.6 to 315.5 W/(m2·K) when the water vapor mass fraction was 10%, decreased 7.10%. And with increasing the water vapor mass fraction from 5% to 25%, the convection–condensation heat transfer coefficient increased from 201.8 to 960.0 W/(m2·K) when the concentration of ash particles was 5.4 g/m3, increased 4.76 times. A normalized correlation of convection–condensation heat transfer coefficient of air/water vapor mixture with ash particles were derived, with the deviation of −12.5% to +12.8%.

In many industrial drying processes, water is evaporated in the drying section by a large volume of fresh air supply, which contains a large amount of sensible and latent heat. Recovering heat and water from the dryer exhaust is a potential way to realize energy and water conservation in drying systems. In this paper, the experimental and theoretical investigations of the waste heat and water recovery characteristics of heat exchangers for dryer exhaust are presented. A hot air and water vapor mixture was used to simulate dryer exhaust. Convection–condensation heat transfer and water recovery characteristics were first obtained under various water vapor mass fractions, flow velocities, and humid air inlet temperatures through experiments, which revealed that the convection–condensation heat transfer coefficient increased with the increase in water vapor mass fraction and humid air velocity, and decreased with the increase in inlet temperature. The condensed water rate increased with the increase in water vapor mass fraction and humid air velocity, while inlet temperature had almost no effect on it. The condensing ratio decreased with the increase in water vapor mass fraction and humid air velocity, while improving the inlet temperature slightly reduced it. Then, a theoretical calculation model was developed to predict the heat and water recovery characteristics of heat exchangers under a wide working condition. In this model, the pipe and suction effects caused by condensation on the tube wall were considered. The properties of humid air were changed according to the temperature and vapor content instead of regarding them as constant values. The calculation results were compared with the present experimental data and those of previous studies. The good prediction accuracy and the universality of the present model were verified. This study is of great significance to the design of heat exchangers.

Marangoni condensation attracts much attention in recent years. This study focused on the effect of tube diameters on Marangoni condensation heat transfer in the case of ethanol–water mixture vapors. Several tube outer diameters, including 0.793 mm, 1.032 mm, 1.221 mm, 10.0 mm, and 20.0 mm, were chosen to indicate the phenomenon, as well as the vertical plate. The ranges of the tube diameters were from macroscale to microscale. The experimental results showed that for pure steam the heat transfer coefficients monotonically increased with the decrease in diameters. For the ethanol–water mixture vapors, the reduction effect of liquid thickness and the accumulation effect of condensate liquid jointly influenced the heat transfer. In the case of macrosurfaces, the promotion effect caused by diameter decrease played a dominant role, and the heat transfer coefficients increased with decreasing the diameters. In the case of microsurfaces, the negative effect of condensate liquid accumulation became active and was the dominant role. The heat transfer coefficients did not always increase with decreasing the diameters, and a critical diameter corresponding to the largest heat transfer coefficients existed.

Lignite is becoming a competitive fuel for power generation with high security of supply and a low price. But a power plant firing lignite directly always has some weaknesses, including low thermal efficiency and high construction investment. Predrying lignite before feeding it to the boiler is a potential method to tackle these weaknesses, and low-pressure steam extracted from steam turbines is considered a competitive heat source for the drying process. In a lignite-fired power system integrated with a steam dryer, the steam extraction is led to the dryer via a connection pipe and depressurization valve. To obtain a stable drying temperature at a variable load of power, steam extraction is often used by the dryer after depressurization, which indeed causes exergy loss. To reduce the exergy loss, the steam extraction was proposed to be supplied to the dryer via a compressor or ejector. Thermodynamic models were developed to calculate the net efficiency of a power system with different energy supply systems. The energy saving boundary—that is, the net efficiency of power system could be increased in some ranges of drying temperature by some energy supply system of dryer—was obtained. Furthermore, the exergy efficiencies were calculated.

The paper presents an experimental investigation of Marangoni condensation heat transfer of ethanol–water vapor mixtures on vertical micro-tubes with an outer diameter of 0.793 mm, 1.032 mm, and 1.221 mm. Experiments were performed over a wide range of ethanol mass fractions in vapor mixtures for different vapor velocities and pressures. Condensation heat transfer coefficients behaved nonlinear characteristics, increased, and then decreased with increasing vapor-to-surface temperature difference. Under the same experimental conditions, the condensation heat transfer coefficient at a 2 % ethanol mass fraction in vapor was the highest. At low ethanol mass fractions, the condensation heat transfer coefficient of the ethanol–water vapor mixture was 2 to 3 times greater than that for pure steam. The effect of vapor pressure and velocity on condensation heat transfer suggested a positive tendency on each micro-tube for all vapor mixtures with different ethanol mass fraction. Results showed that condensation heat transfer coefficients on micro-tubes with a diameter of 1.032 mm were higher than those on the other two micro-tubes, suggesting that there existed a critical diameter which gave the largest condensation heat transfer coefficient.

When the ejector was applied in the natural gas exploitation and sea water desalination industries, the ejector always operated on the two phase operation, because of the primary fluid or the induced fluid usually companying some water inside. The water inside the primary and induced gas will affect the ejector performance. In the present study, the experimental and CFD methods were used to investigate the two phase flow inside the ejector, when the water was injected into the induced flow. The results show that: when the water was injected into the induced flow, the experimental results decreased, as well as numerical results. The numerical results agreed with the experimental data, with the maximum deviations less than 20% for critical mode and less than 40% for sub-critical mode
