分布式热电联产中热电比的确定

Rational determination to heat and power ratio for distributed CHP Plant

分布式供能是国际上近几年发展起来的一种新的能源供应概念和方式。在分布式热电联产系统中,余热锅炉补燃是调节热电负荷的有效手段,选择合适的补燃率有助于提高余热锅炉和分布式热电联产系统的效率。本文基于上海理工大学分布式热电联产实验台的数据,通过与购买市电+单独燃油锅炉供热进行比较,给出了一种确定最佳热电比的方法。

The distributed energy system is a kind of new energy supply concept and mode which is widely used recently. In distributed energy system, the supplementary firing for HRSG is an available means to regulate the heat and power load. To improve the efficieney of HRSG and the energy island system,it is necessary to select appropriate supplementary firing rate. In this paper, a method to optimize the heat and power ratio is given by comparing the CHP and purchasing the electricity and the oil - firing boiler.
