一种循环流化床锅炉协同处置多源固废的系统装置及系统方法
By adopting a staged co-firing system in a circulating fluidized bed boiler, high-moisture sludge enters the furnace from the top material inlet for drying and incineration, while low-moisture sludge is mixed with the bed material. This solves the problem of blockage in the conveying system caused by high-moisture sludge and improves the safety and handling capacity of the co-firing system.

AI Technical Summary
When processing sludge with high water content, circulating fluidized bed boilers face difficulties in fuel ignition, which can easily lead to blockage of fuel transport pipelines and limit co-firing capacity.
A graded co-firing system with different material inlets is adopted. High moisture content sludge enters the furnace from the top material inlet for drying and incineration, while low moisture content sludge is mixed with bed material and then enters the furnace. The furnace is used for high-temperature drying to reduce sludge viscosity and prevent blockage of the conveying system.
It improves the safety of the co-firing system and the diversity of fuel sources, effectively disposes of multi-source solid waste, prevents blockage of the conveying system, and enhances the co-firing capacity of the circulating fluidized bed.
