新标准颁布后的燃煤电厂消防给水设计

Design of Fire Protection Water Supply for Coal-fired Power Plants After the New Code Published

目前燃煤电厂消防给水设计标准遵循GB 50229-2006《火力发电厂与变电站设计防火规范》和GB 50974-2014《消防给水及消火栓系统技术规范》,其中若干条文规定存在较大差异。对规范中消防用水量和压力设计、消防给水设备选择、消防水泵接合器设置、室内消火栓布置等条文进行分析研究,并结合工作经验,对目前正在设计的某内陆电厂消防给水设计进行复核修正,可供设计人员参考。

At present, design code of fire protection water supply for coal-fired power plants should follow Code for Design of Fire Protection for Fossil Fuel Power Plants and Substations（GB 50229-2006） and Technical Code for Fire Protection Water Supply and Hydrant Systems（GB 50974-2014）, between which there are significant differences in some articles. The paper analyzes and investigates articles such as design of water consumption and pressure, selection of fire protection water supply equipment, setting of fire pump adapter and arrangement of indoor fire hydrants. The paper also reviews and corrects the design of fire protection water supply for one inland power plant, which can be used by designers as reference.
