摘　　要：为分析低低温电除尘技术对某1 000 MW超超临界机组热经济性的影响,基于电厂热力系统热经济性状态方程及小扰动理论,建立了烟气余热利用的热经济性评价方法。计算及试验结果表明,机组实施低低温电除尘技术改造后,供电标煤耗降低可达2.3 g/k Wh。In order to study the thermal economy of ＂low - low temperature ESP＂ in a 1 000 MW ultra - supercritical unit, a new method of calculation of flue gas waste heat recovery was put forward, which was established based on the state equation and the theory of Small Disturbance about thermal economy of thermal system. The results showed that by using the low - low temperature ESP, the consumption of standard coal was reduced by up to 2.3 g/（ kW. h）.
