Abstract

The invention discloses a boiler provided with a dual-register pulverized coal burner on the top, belonging to the technical field of boilers, and aiming at providing a U-shaped flame boiler which is provided with the dual-register pulverized coal burner on the top and is high in combustion efficiency. According to the technical scheme, the boiler provided with the dual-register pulverized coal burner on the top comprises a boiler body and an ash falling pit, wherein the ash falling pit is formed in the bottom of the boiler body, a membrane type water-cooling wall is arranged on the inner wall of the boiler body, a first partitioning wall is arranged on the top in the boiler body and is used for partitioning the boiler body into a combustion chamber and a waste gas chamber, the lower parts of the combustion chamber and the waste gas chamber are communicated with each other to form a first pair of flue channels, the dual-register pulverized coal burner is arranged at the top of the combustion chamber, a second partitioning wall is arranged at the bottom of the waste gas chamber and is used for partitioning the waste gas chamber into a left chamber and a right chamber, the upper parts of the left chamber and the right chamber are communicated with each other, and a flue discharging channel is arranged at the bottom of the side wall of the right chamber. The boiler is high in heat utilization rate and less in waste gas emission.

Description

technical field [0001] The invention belongs to the technical field of boilers, and in particular relates to a U-shaped boiler with double air-regulating pulverized coal burners placed on top. Background technique [0002] The boiler industry is a large coal-consuming household in my country, and energy conservation and emission reduction in the boiler industry have a decisive impact on the realization of the national energy consumption reduction target. The development trend of boiler technology is the increase of capacity and the improvement of parameters, among which the development of combustion technology is an important aspect. The pulverized coal burner is a key component of the boiler combustion equipment. Its main function is to deliver fuel and air to the furnace to achieve reasonable mixing and combustion. With the increasing pressure of environmental pollution, the control of burner emissions has become an important indicator of burner performance. [0003] The...
