A biomass energy particle gasification combustion boiler

Abstract

The invention relates to the field of biomass energy combustion equipment, and discloses a biomass energy particle gasification combustion boiler. The biomass energy particle gasification combustion boiler comprises a boiler body; a slag discharge chamber is formed in the bottom of an inner cavity of the boiler body; a feeding box is arranged at the bottom of the side surface of the boiler body; acharging bin positioned at the external of the boiler body is arranged at the top of the feeding box; and one end of the feeding box extends into the boiler body. In the biomass energy particle gasification combustion boiler, through design of a guide box at the bottom of the combustion boiler, a first ventilation pipe, an exhaust pipe, a second ventilation pipe and an exhaust ring, biomass fuelparticles are fed on a fuel loading plate in the combustion boiler from the top of the guide box; in the period of stopping charging, the exhaust pipe is used for continuously exhausting, so that thefuel combustion is facilitated; and meanwhile, air currents scattered outwards are formed at the top of the guide box, so that the combustion phenomenon cannot be generated at the top and in the guidebox to effectively guarantee the maximal utilization of biomass combustion particles.

Description

technical field [0001] The invention relates to the field of biomass energy combustion equipment, in particular to a biomass energy particle gasification combustion boiler. Background technique [0002] Biomass mainly refers to agricultural and forestry production, crop straw, wood and other wood cellulose, agricultural product processing industry leftovers, agricultural and forestry waste. As a large agricultural country, my country has a large amount of crop straw, wood and other wood and other cellulose. Biomass energy is abundant, so biomass energy is processed to achieve effective utilization. Among them, crop straw, etc. are crushed into particles and burned in a biomass combustion boiler, so that the heat energy generated can be effectively used. [0003] However, it takes a certain amount of time for the existing biomass particles to burn to the end. The existing combustion boilers mostly use the auger structure to automatically feed, which makes the biomass particles...

Problems solved by technology

[0003] However, it takes a certain amount of time for the existing biomass particles to burn to the end. The existing combustion boilers mostly use the auger structure to automatically feed, which makes the biomass particles at the feeding channel in the combustion chamber also burn during the stop of feeding. Combustion, thus wasting resources, and the existing feeding method is added from one side, so that the biomass pellet fuel is concentrated on one side, which affects the combustion effect in the combustion chamber, thereby reducing the utilization rate of biomass pellets
