摘要

结合兖矿国宏化工公司2台160t/h循环流化床锅炉(CFB)掺烧弛放气、煤泥、洗中煤、矸石、气化炉灰渣等混合燃料的运行经验

分析掺烧混合燃料时炉膛负压、料层厚度、主蒸汽温度、排烟温度等参数的运行特点

以及包括锅炉除渣系统、受热面磨损、给煤系统、除灰输灰系统的运行维护措施。经验可为CFB锅炉掺烧混合燃料

实现废物综合利用提供一定借鉴。

Abstract

Combined with experiences in operation of two 160 t/h CFB boiler in Yankuang Guohong Chemical Company for mixedly burning blended fuels

such as relaxedly deflated gas

coal slime

washed middling coal

gangue

ash and slag from gasified furnace etc.

the features of adjustment in operation for the negative pressure in furnace

the thickness of material layer in CFB boiler

the temperature of main steam

the temperature of discharged flue gas etc.

as well as some measures in operation and maintenance

including slag removal system of the boiler

abrasion of the heating surface

the coal haddling system

and the ash removal and conveying system etc.

have been analysed

providing certain reference for mixedly burning blended fuel

and realizing comprehensive utilization of wastes.
