基于汽轮机乏汽余热利用空冷供热机组的灵活性调峰应用研究

Flexible Peak Regulation of Air-cooling Heat Supply Unit Based on Turbine Waste-heat Utilization

随着城市供热改造进度的逐渐深入,以某热电公司为例,该公司接带的供热面积逐年增加,而电量形势不容乐观,面临小电量、大供热的外部环境。针对该难题,该公司从大温差换热出发,优化供热运行方式,研究最小的电量和最大的供热量的配比关系,确定供热机组的最小电负荷,确认机组深度调峰负荷,满足供热机组50%负荷的调峰能力。通过该技术方案的实施,实现了供热机组深度调峰。

With the gradual progress of urban heating reform, the heating area supplied by Shanxi Datang International Yungang Thermal Power Co., Ltd.（hereinafter referred to as ＂the company＂） increased year by year, while the electricity supply situation is not optimistic. In view of this problem, the company optimized the heating mode and studied the ratio between the minimum electricity supply quantity and the maximum heat supply quantity to determine the minimum heating load of the unit to confirm the unit deep peak-regulating load. Through the implementation of the technical program, the deep participating in peak regulating in heating unit has been achieved.
