Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology and solve the high content of sulfur trioxide in the flue gas produced by burning straw in the prior art, when the flue gas passes through the pipe of the burner, sulfur trioxide will form sulfate on the inner wall of the pipe, due to sulfuric acid Salt has a certain corrosiveness and will corrode the inner wall of the pipeline. The present invention proposes a biomass boiler denitrification combustion device

Abstract

The invention belongs to the field of boiler combustion equipment, and particularly relates to a biomass boiler denitration combustion device which comprises a boiler body. A low-nitrogen combustor is fixedly connected to the side wall of the furnace body, a pipeline is communicated between the low-nitrogen combustor and the furnace body, a water tank is arranged on one side of the furnace body, the water tank is fixedly connected with the furnace body through a support, a water inlet is formed in the top end of the water tank, and a heating pipe is communicated in the water tank. A natural gas heater is fixedly installed at the other end of the heating pipe, the bottom end of the water tank communicates with a water inlet pipe, a first valve is installed on the water inlet pipe, the end, away from the water tank, of the water inlet pipe communicates with a pipeline, and a water baffle is slidably connected into the pipeline. Warm water in the water tank enters the pipeline from the water inlet pipe, sulfate on the inner wall of the pipeline can be washed by the warm water, the effect of washing the sulfate on the inner wall of the pipeline is achieved, the situation that the sulfate corrodes the inner wall of the pipeline is avoided, and the service life of the pipeline is prolonged.

Description

technical field [0001] The invention relates to the field of boiler combustion equipment, in particular to a biomass boiler denitrification combustion device. Background technique [0002] Biomass refers to straw and wood chips. The boiler uses a low-nitrogen burner to burn the straw, and then denitrifies the flue gas generated during the combustion. [0003] There are also some technical solutions about boiler combustion equipment in the prior art. For example, a Chinese patent with application number CN201510073991.0 discloses a biomass boiler denitrification combustion device and a double-burner biomass boiler, including a combustion chamber and a device. The burner in the combustion chamber has a feed inlet and an air inlet in the middle of one end of the combustion chamber, and a flame nozzle at the other end of the combustion chamber. In particular, the outer layer of the flame nozzle is provided with a coaxial outer casing of the nozzle. The tube-in-tube tube and the...
