This determines the level of decomposition of the wastes. High air flow means total combustion while low inflow of air means partial combustion. Total combustion means low quantity of gases.
The operation of the incinerator will also determine the quantity of gaseous products produced and their composition. The type of handling the materials are given dictates the quantity and composition of gases produced. Operation determines the temperature of combustion and the level of mixing as well as the amount of air allowed in (Oppelt 1987). Operation also determines the residence time that the combustion process takes and the type and amount of fuel to be used in the combustion Fuel also contributes to gaseous products. All these factors have a bearing on the quantity and composition of the gaseous products coming out of the incinerator
The properties of the waste materials also determine the quantity and composition of the gases produced. Different types of waste materials produce different gaseous compositions in different quantities. Waste materials have different physical and chemical properties which result in production of different quantities and compositions of gases (Oppelt 1987).The quantity of residues is determined by the quantity of the waste products that are fed into the incinerator. The residence time of the wastes in the incinerator, the temperature, quantity of oxygen and level of mixing determine the level of combustion hence the amount of residue produced. When there is absolute combustion then little residue is produced (Oppelt 1987).
