Background technology
The theory of combustion of solid combustible thing is divided into three phases：First is the stage before catching fire, including combustion is dried, separates out and wave
Hair point and formation solid-state charcoal, solid combustible thing are heated in stove, dry, evaporate moisture, and as temperature increases, wherein organic matter is opened
Begin thermal decomposition, the side chain to get off be mainly broken from macromolecular and volatile matter that functional group is formed, its main component be CO,
CO2, H2, H2O, CH4 and various hydrocarbon compounds, the resultant product of thermal decomposition is solid-state charcoal, in the process solid combustible thing
Absorb heat；Second is the burning of volatile matter and charcoal, the initial burning when temperature reaches burning-point, then flammable volatile matter and solid
State carbon starts to burn, and the volatile matter of solid combustible thing is higher, and burning velocity is faster；3rd is remaining solid carbon combustion in clinker
Cinder.
The corresponding above-mentioned theory of combustion, the burning of solid combustible thing are divided into three layers, including burning ash layers positioned at bottom, position
Oxidizing fire layer above burning ash layers, the drying reducing zone above oxidizing fire layer, reducing zone top are volatilizations
Point and charcoal burning caused by flame.
All it is from the burning ash layers supply air of the bottom of fire grate, i.e. fuel, so sky in existing furnace grate technology
Gas preferentially supplies imperfect combustion ashes and burnt away, and discharges remaining heat energy；Oxidizing fire layer is provided to be burnt,
