摘要

为探究掺烧生物质对锅炉最低稳燃负荷的影响

以某电厂1 000 MW超超临界旋流对冲锅炉为研究对象

模拟了不同负荷下纯煤工况以及添加掺烧比为10%的棉秆后锅炉内的燃烧状况

分析对比了不同负荷下炉膛内的温度分布和烟气氧气浓度分布

探讨了掺烧生物质后锅炉最低稳燃负荷的演变。结果表明:与纯煤工况相比

掺烧棉秆后燃烧器中心截面温度高于1 400 K的区域增大

着火距离缩短0.24%~3.45%

炉膛出口氧气浓度上升0.22%~0.24%

燃烧稳定性增强;该锅炉燃用设计煤种的最低稳燃负荷为40%

掺烧棉秆后锅炉最低稳燃负荷可降至30%

因此掺烧生物质可以有效地促进旋流对冲锅炉内的稳燃性能

降低锅炉的最低稳燃负荷

增强锅炉的深度调峰能力。

Abstract

To investigate the effect of biomass co-firing on the lowest steady combustion load of the boiler

a 1 000 MW ultra-supercritical swirl-opposed boiler was taken as the research object. The combustion conditions of pure coal and the addition of cotton stalk(CS) with a co-firing ratio of 10% were simulated under different loads in the boiler. The temperature distribution and oxygen concentration distribution in the furnace under different loads were analyzed

and the evolution of the minimum stable combustion load of the boiler after co-firing biomass was explored. Results show that compared with pure coal conditions

the area with the temperature above 1 400 K of the central section of the burner increases after co-firing cotton stalks

the ignition distance is shortened by 0.24%-3.45%

the oxygen concentration at the furnace outlet increases by 0.22%-0.24%

and the combustion stability is greatly enhanced. The lowest steady combustion load of the designed coal is 40%

and the lowest steady combustion load of the boiler mixed with CS can be reduced to 30%. Therefore

biomass-mixed combustion can effectively enhance the steady combustion performance and decrease the lowest steady combustion load of the swirl-opposed boiler

and thus the peaking capability of the boiler can be promoted.
