In order to study the design of the fire water supply system of large scale fossil fuel power plants,this paper analyzes the design of the fire water supply zoning system of a 1 350 MW coal-fired unit and two 1 000 MW coal-fired units under the current specifications from the perspective of practical engineering,and obtains the optimal scheme suitable for practical engineering.If there is the most unfavorable pressure point requirement of local high pressure and low flow in large scale fossil fuel power plants,the series partition water supply and local pressure boosting mode shall be adopted;If the most unfavorable pressure point requirements of high pressure and large flow exist in large scale fossil fuel power plants,the water supply mode of parallel network and partition shall be adopted.
