The gasification layer from rubbish is connect, gasification furnace is extracted out by each layer of rubbish.Also a small amount of gasification furnace sets built-in air flue, but due to
It is influenced that flue gas can be caused to burn in gasification furnace by in-furnace temperature, affects gasification result, while built-in air flue also affects
The working conditions such as spice of the rubbish in gasification furnace.Shortcoming and defect：(1) flow of flue gas speed is slow.Due to by gasification layer upper layer
The influence of rubbish stacking pressure causes flue gas discharge to be obstructed, and circulation is unsmooth, and draw speed is slow.(2) gasification efficiency is low.Due to flue gas stream
Logical unsmooth, flowing velocity is slow, and leading to the combustible gas for gasifying, some has just been burned off in gasification furnace, causes simultaneously
The in-furnace temperature that gasifies is excessively high, and adverse effect is caused to gasification result.(3) fume treatment effect is influenced, by flow of flue gas speed
Slowly, the low influence of gasification efficiency, the flammable tolerance that flue gas enters combustion chamber is inadequate, causes chamber temperature too low, has in flue gas
Evil ingredient cannot be destroyed, and influence the effect of fume treatment.
