Abstract
The utility model discloses a waste heat steam boiler for reciprocating grate residue incineration, which comprises a reciprocating grate and three radiation chambers, i.e. a first radiation chamber, a second radiation chamber and a third radiation chamber. The first radiation chamber is arranged above the reciprocating grate, and the second radiation chamber and the third radiation chamber are sequantially connected beside the first radiation chamber. The two sides of the boiler above the reciprocating grate are respectively provided with a combustor. When the utility model is used, the flammable gases generated in residue combustion can be fully burned, the dust generated during the combustion can be settled, and the fuels which have low calorific values and can not be easily ignited and burned can be fully burned. With the combustors arranged on the two sides of the boiler, the detention period of the fume in the first radiation chamber is prolonged, so the toxic and harmful gases generated during the combustion can be effectively controlled. Moreover, since a group of evaporation tube screens are arranged in the radiation chambers, the distribution of the absorbed heat on each part of the boiler is uniform.
