基于全厂水平衡试验的燃煤电厂深度优化用水分析

Analysis of water use for deep optimization of coal-fired power plant based on whole plant water balance test

根据《火力发电厂水务管理导则》(DL/T 1337-2014)、《火力发电厂能量平衡导则》(DL/T 606.5-2009)第5部分:水平衡试验,要求,对某燃煤电厂2×145 MW+2×335 MW机组进行全厂水平衡试验,掌握了全厂及各子系统的取水、用水、排水现状,对现有水量数据及用水指标进行分析评价,提出了电厂深度优化用水方案,预期节水效果较为明显。

According to requirements of《Guidelines for water management in fossil fuel power plants》(DL/T 1337-2014)、《Guide for energy balance of thermal power plant Part 5:water balance test》(DL/T 606.5-2009),the water balance test of 2×145 MW+2×335 MW units in a coal-fired power plant is carried out,and the present situation of water intake,water use and drainage in the whole plant and its subsystems is grasped.The existing water quantity data and water use index are analyzed and evaluated.The water use scheme for deep optimization of power plant is put forward,and the expected water saving effect is obvious.
