Then the biomass particles enter the material receiving and storing mechanism in sequence, after the biomass particles enter one of the storing plates 11, the driving mechanism is started to drive the rotating ring block 13 to rotate, then new biomass particle raw materials are put into the storing plates 11 for placing the raw materials, the circulation is carried out repeatedly until the raw materials on the storing plates 11 are all fully stored, at the moment, the raw materials in the combustion chamber 3 are combusted to generate a large amount of heat, a small part of the heat is dissipated in the combustion chamber 3, the raw materials on the storing plates 11 are dried, after the drying, the lifting mechanism is directly started to enable the feeding ring 12 to move upwards, the feeding ring 12 supports against the storing plates 11, the storing plates 11 are turned inwards, the raw materials on the storing plates 11 enter the filtering combustion net 5 and then are combusted, at the moment, new wet raw materials are sent to the storing plates 11 to be dried, at the moment, the raw materials are dried, can not produce dense smoke, be fixed with a pipeline by supreme grow gradually down on the filtration burning net 5 in the combustion chamber 3, the living beings granule is when getting into filtration burning net 5, and the raw materials can pile up at the middle part, prevents flame diffusion, will be located marginal living beings granule and burn.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
