Low temperature heat and water recovery from supercritical

Abstract. One way to improve the efficiency of a coal-fired power plant is to recover the low temperature waste heat from the flue gas and use it to preheat combustion air or boiler feedwater. A low temperature economizer or flue gas cooler can be used for this purpose to :Andrew Reimers:Efficient energy use · Flue gas[PDF]INDUSTRIAL WASTE HEAT USED IN TYPICAL THERMAL be a technology that can use the low temperature waste heat (<100 °F) to treat water. By their nature, they operate at low temperature and usually low pressure. 2. BOILER AND STEAM CYCLE In fossil-fueled power plants, steam generator refers to a furnace that burns the

Research Paper WASTE HEAT RECOVERY USING STIRLING

Table 3 lists some heat sources in the low temperature range. In this range it is usually not practical to extract work from the source, though steam production may not be completely excluded if there is a need for low-pressure steam. Low temperature waste heat may be useful in a supplementary way for preheating purposes.
