严寒地区火电厂输煤建筑供暖系统运行效果分析

Operation effect of heating system for coal handling structures in thermal power plant in severe cold zone

分析了严寒地区火电厂输煤建筑供暖热媒特点,指出高温热水比蒸汽具有更多优点而应用得越来越广泛;针对几个电厂输煤建筑出现供暖系统效果不理想的现状,从设计、设备采购、施工、运行管理等各方面提出需注意的问题,如加强围护结构保温、回水管上设静态平衡阀、根据规范施工等。

Analyses the characteristics of the heating medium.Points out that high temperature water is widely used because of more advantages than steam.In view of the dissatisfied heating effect in coal handling structures of several plants,puts forward some suggestions such as enhancing the heat insulation of building envelope,setting static balance valves on return water pipes and constructing according to correlative guides,to which due attention should be paid in design,procurement,construction and operation management,etc.
