低真空循环热电机组与热水锅炉联合供热改造

Reconstruction of Combined Heating of Low Vacuum Circulating Thermal Power Units and Hot Water Boiler

某热电厂采取部分热电机组低真空循环水直接供热方式,存在剩余部分发电机组排汽余热利用不充分及不利于热网运行调节的问题。为满足增长的供热需求,在对剩余部分发电机组进行低真空改造的基础上,联合热水锅炉,实现热电机组与热水锅炉联合供热方式(采用高温供水、间接连接方式)。

A thermal power plant uses low vacu um circulating water from part of the thermal power u nits for direct heating, and there are problems inclu ding inadequate utilization of exhaust waste heat from the remaining part the thermal power units and unfavor able adjustment of the heatsupply network operation. On the basis of the low vacuum reconstruction of the remaining part of the thermal power units, the com bined heating mode of the thermal power units and hot water boiler is achieved by high temperature supply wa ter and indirect connection to meet the growing demand of heatsupply.
