严寒地区电站锅炉房的通风与供暖防冻设计
Ventilating, heating freeze-proofing design for boiler rooms of power plant in severe cold zone
摘要：
严寒地区一般在电站锅炉周围采用复合型保温压型钢板进行封闭，形成封闭围护结构，称为紧身封闭锅炉房；认为紧身封闭锅炉房冬季运行底层温度偏低、管道冻裂的主要原因是热压作用下的大量冷风入侵，指出在设计过程中要综合考虑锅炉房的夏季全面通风与底层冬季供暖防冻，锅炉房运转层平台的钢格栅、开口、楼梯间等造成运转层上下部空气流通部位的尺寸需要合理控制，并简要描述了冬季循环通风系统的设计与应用。
Abstract：
The boiler in power plant in severe cold zone generally is enclosed with composite insulating profiled steel sheet, and such an enclosed structure is called a tight-enclosure boiler room. Considers that the main causes for lower indoor temperature and water pipe frost-crack in ground floor in the boiler room in winter are infiltration of cold wind by stack effect pressure. Suggests that it should be considered in design to ventilate in summer and heat for freeze-proofing in ground floor in winter. The sizes of steel grid, opening, stair on operating floor should be properly controlled to reduce infiltration in winter. Presents the design and application of circulating ventilation system in winter.
