Comprehensive reconstruction of chain grate boiler for energy saving and consumption reduction

In consideration of the very frequent load fluctuations of chain grate boilers with a steam capacity of 10 t/h and lower a dynamic mathematical model was set up by using a modular modeling method for the steam-water system and combustion system of a 10 t/h chain grate boiler.

Imperfections that appear in stratified combustion of chain grate boilers have successfully been dealt with, to raise the boilers output and efficiency and also to alleviate contamination caused by smoke and dust.
