摘要

为突破循环流化床(CFB)机组因锅炉燃料侧存在大量惰性床料而导致负荷响应慢等技术难题

选取以煤矸石为燃料主要成分的CFB机组为研究对象

建立并验证了机组热力系统动态仿真模型

获得了机组爬坡过程中输出功率、主蒸汽温度、主蒸汽压力、床温、锅炉蒸发量及循环效率等关键热力参数性能。为提升机组爬坡性能

提出了在CFB机组炉膛上部动态混烧煤粉以削弱煤矸石燃烧惯性影响的优化方案。结果表明:在3%/min爬坡速率下

优化方案使输出功率、主蒸汽压力、主蒸汽温度、再热蒸汽温度和床温的最大偏差分别降低到1.31%、0.81%、2.3 K、3.5 K和27.8 K

均被控制在DL/T 657—2015《火力发电厂模拟量控制系统验收测试规程》标准中相应偏差的规定范围内;采用优化方案后

CFB机组的最大允许爬坡速率从2%/min提升至3%/min

且机组热经济性略有提升。

Abstract

To address the technical difficulties of slow load response in circulating fluidized bed (CFB) power units due to the presence of large amounts of inert bed material on the fuel side of the boiler

a CFB power unit primarily fueled by coal gangue was focused on. A dynamic simulation model of the power unit's thermal system was established and validated

obtaining performance of key thermodynamic parameters such as output power

main steam temperature

main steam pressure

bed temperature

boiler evaporation rate and cycle efficiency during the load ramp-up process. To improve the power unit's load ramp-up capability

an optimization scheme involving dynamic co-firing of pulverized coal in th

e upper part of the CFB furnace was proposed to mitigate the inertial effects of coal gangue combustion. Results show that at the load ramp-up rate of 3%/min

the optimization scheme reduces the maximum deviations of output power

main steam pressure

main steam temperature

reheat steam temperature and bed temperature to 1.31%

0.81%

2.3 K

3.5 K and 27.8 K respectively

all within the specified range of the DL/T 657—2015

Code for Acceptance Test of Modulating Control System in Fossil Fuel Power Plant

standard. With the optimization scheme

the maximum allowable load ramp-up rate of the CFB power unit increases from 2%/min to 3%/min

while slightly improving the power unit's thermal economy.
