Combustion method and apparatus.

摘要

An apparatus for incinerating waste material comprising means (32) for feeding waste material in batches to a main combustion region (29), burners (26, 28) for burning said batches thereby to form gaseous combustion products, a secondary combustion region (30) for burning combustibles in said combustion products, means (40) for supplying oxygen to said secondary combustion region to support combustion and means (56) for controlling the supply of oxygen. The quantity of oxygen supplied being altered as a function of monitored concentration of a least one component of the combustion product or the flue gas thereby to compensate for the variation in calorific value of different batches of waste. <IMAGE>
