DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present disclosure is further described below in combination with the accompanying drawings.

[0025] As shown in FIG. 1 to FIG. 4, the boiler for co-firing municipal solid waste and short timber for cultivating fungus in the present embodiment includes a boiler chamber 18 and a fire grate 1. The boiler chamber 18 includes a furnace 2, a reburning chamber 3 and a third flue 4. A front arch 7 and a rear arch 8 are arranged on a lower portion of the furnace 2 and located above the fire grate 1. Multiple layers of secondary air 9 are distributed at the lower portion of a front wall of the furnace 2, the front arch 7 and the rear arch 8. An short timber for cultivating fungus feeding device 13 is arranged on a lower portion of the front wall of the furnace 2, and includes a star-shaped feeding machine 14 and a hopper 16. A skin expansion joint 15 is arranged between the star-shaped feeding machine 14 and the hopper 16, and an air pipe 17 is arranged on the hopper 16. The reburning chamber 3, the third flue 4, a horizontal flue 5 and a tail flue 6 are sequentially arranged behind the furnace 2. The boiler internal desulfurization nozzles 10 and the Polymer Non-Catalytic Reduction (PNCR) denitration nozzles 11 are arranged in a height direction of the furnace 2. A baking soda dry deacidification nozzle 12 is arranged at a top of the tail flue 6.
