摘要

针对燃煤供热机组热电解耦困难、调峰能力受限等问题

建立了供热机组稳态模型

通过配置熔盐储热系统辅助供热

研究了蓄热供汽比例

对系统调峰能力与热力学性能的影响

并基于TOPSIS方法进行综合评价

确定了最佳供热模式。结果表明:

对系统调峰能力和能效具有正向促进作用;熔盐供汽承担全部供热负荷时为最佳模式

此时储热过程机组出力从248.15 MW降至176.34 MW

实现深度调峰容量为15.66 MW

释热过程出力升至345.40 MW

实现顶峰超发容量为25.40 MW

双向拓宽了运行区间;该模式兼具高效与低碳特性

储热和释热模式下热效率分别达48.89%和60.94%

效率分别为35.13%和37.86%

全过程供电煤耗率为290.15 g/(kWh)

碳排放量为677.14 g/(kWh)。

Abstract

To address issues such as difficult heat-power decoupling and limited peak-shaving capacity in coal-fired cogeneration units

a steady-state model of the cogeneration unit was developed

and a molten salt heat storage system was integrated to assist in heat supply. The impact of the heat storage steam supply ratio

on peak-shaving capability and thermodynamic performance was studied. A comprehensive evaluation was conducted based on the TOPSIS method

and the optimal heating mode was determined. Results show that the

has a positive promoting effect on the system's peak shaving capacity and energy efficiency. The optimal mode is when molten salt steam supply undertakes the entire heating load. Under this condition

the unit power output decreases from 248.15 MW to 176.34 MW during the heat storage

process

achieving a deep peak shaving capacity of 15.66 MW. During the heat discharge process

the output power increases to 345.40 MW

realizing a peak over-generation capacity of 25.40 MW

which bidirectionally expands the power regulation range. This mode features both high efficiency and low carbon properties. Under the heat storage and heat discharge modes

the energy efficiency reaches 48.89% and 60.94% respectively

the exergy efficiency is 35.13% and 37.86% respectively

the round-trip coal consumption rate for power supply is 290.15 g/(kWh)

and the carbon emission amount is 677.14 g/(kWh).
