Estimating the term…
In a method of incinerating waste material in a parallel flow process wherein hot exhaust gases are conducted above a combustion chamber grate in the same direction as the material is moved on the grate, different temperatures zones are maintained to which air is admitted from the bottom through the grate such that a temperature of less than 900.degree. C. is maintained in a first zone which is a drying zone, a temperature of about 1000.degree. C. is maintained in a second zone which is an evaporization and vaporizing zone, a temperature of about 900.degree. C. is maintained to in a third zone, which is the final combustion zone and a temperature less than 900.degree. C. is maintained in a fourth zone which is a sintering zone. Additional air is supplied to the combustion zones 1 through the side walls of the combustion chamber. A dividing wall is disposed above the grate over which the hot combustion gases are conducted to a discharge opening so that heat is transferred to the dividing wall for radiation back onto the waste material on the grate.
A method of incinerating waste material in a waste incinerator having a combustion chamber with different zones disposed between opposite side walls of the chamber, and a grate on which waste the material is moved through said combustion chamber and through which primary air is supplied from below grate to the waste material for combustion of the waste material in said zones to form hot combustion gases which are conducted both above the waste material on the grate in parallel flow with the movement of the waste material on said grate and below installation components disposed above the grate and which gases are then conducted above the installation components to a discharge opening in counter-current flow to the flow of said combustion gases above the grate, said method comprising the steps of:
An incineration apparatus including a combustion chamber having a grate on which waste material is moved through the combustion chamber, installation components disposed above said grate, side walls disposed at opposite sides of said grate and tightly receiving therebetween said installation components, said installation components forming an intermediate wall extending over the length of said grate and dividing said combustion chamber into a primary area between said grate and said intermediate wall and a secondary area between said intermediate wall and the top of said combustion chamber and forming at the end of said intermediate wall a flow reversal area for reversing the flow of the combustion gas flowing in said primary area in the same direction as the waste material on said grate and in said secondary area in the opposite direction, said side walls including cooling air passages and having, at least in some areas, between said primary area and said cooling air passages, a permeability for air such that air supplied to said cooling air passages can pass through said side walls into the respective primary combustion chamber areas.
