锅炉排烟余热高能级深度利用研究

Research on the Depth of Exhaust Heat and Smoke Removing of Boiler

本文对1000MW级超超临界机组加装低温烟气换热器方案做了简单的介绍,通过除尘器入口及引风机出口设置低温烟气换热器的方式,采用凝结水换热,降低吸收塔入口烟气温度,同时减少了低加回热抽汽量,实现高效节能、节水。

This paper does a simple introduction for 1000MW Ultra Supercritical Unit with low temperature flue gas heat exchanger scheme. To set the way of low-temperature flue gas through the precipitator entrance and the draft fan outlet heat exchanger, transfer heat by condensation, reduce the absorption tower entrance flue gas temperature, while reduce the low regenerative steam quantity can achieve high efficiency energy saving and water saving.
