Coal and biomass fired boilers are usually chain grate stoker type or circulating fluidized bed / CFB type. Both of the two kinds of boilers have their own advantages, but sometimes people will choose the stoker type boiler to meet their requirement. Surely the stoker boilers have advantages over the CFB ones under some conditions.
What is a stoker boiler
Stoker boiler, also called chain grate boiler, the coal is burnt on a chain grate which continuously travel forwards slowly combustion takes place during the journey of coal from first end to last end of the furnace. At the end of the combustion heavier ash content falls into ash pit by gravitational force as the grate chain moves like conveyor belt. The lighter ash particles and combustion gases fly away with primary air.
When to Choose a Stoker Boiler:
Low capital costs are paramount
Low operations & maintenance cost are targeted
When a customer expects to burn fuels with either of the following conditions:
Low ash fusion temperatures in the fuel
High alkali content in the fuel
