Biomass briquette gasified combustion normal pressure hot-water boiler

Abstract

The invention discloses a biomass briquette gasified combustion normal pressure hot-water boiler, and belongs to the technical field of biomass briquette boilers. The problems existing in an existing biomass briquette boiler are solved. The biomass briquette gasified combustion normal pressure hot-water boiler comprises a burner, a gas combustion chamber and a flue. The burner comprises a gasification combustion chamber. The bottom of the gasification combustion chamber is provided with a fire grate and primary air openings. A gas nozzle is arranged at the side, far away from a feeding inlet, of a gas collecting area, and a secondary air opening is formed in the gas nozzle. The gas combustion chamber is arranged in front of the gas nozzle. A reciprocating grate is adopted in the fire grate. A separating wall perpendicular to the fire grate direction is arranged inside the gasification combustion chamber, and air holes are formed in the upper side of the separating wall. Rotational flow blades are arranged in the secondary air opening. Threaded smoke tubes are arranged inside the flue, and a normal pressure water tank is arranged outside the threaded smoke tubes. Heat exchange water pipes are arranged inside the normal pressure water tank and located above the threaded smoke tubes. The biomass briquette gasified combustion normal pressure hot-water boiler is used for biomass briquette gasified combustion heat supply.

Description

technical field [0001] The invention belongs to the technical field of biomass briquette fuel boilers, and in particular relates to a biomass briquette fuel gasification combustion atmospheric pressure hot water boiler. Background technique [0002] Biomass briquettes such as straw particles have many advantages such as high calorific value, environmental protection, and regeneration. The existing biomass briquette fuel burners are prone to slagging in the gasification chamber, and need to be shut down frequently for manual slagging, which cannot Continuous operation; Insufficient combustion; Direct-flow flame is generated, the diameter of the flame is small, the length is large, and it is directly sprayed onto the back wall to cause serious slagging of the back wall, resulting in a short maintenance cycle, and the molten slag on the back wall needs to be cleaned regularly, which is labor intensive and Problems such as low heat utilization rate need to be solved.
