Biomass particle hot-water boiler with double combustion chambers

Abstract

The invention discloses a biomass particle hot-water boiler with double combustion chambers, belonging to the technical field of heat-source equipment. The biomass particle hot-water boiler with the double combustion chambers comprises a furnace body, a fire grate, a combustion chamber and an ash falling chamber, wherein the furnace grate is arranged at the lower end of the inner part of the furnace body; the combustion chamber and the ash falling chamber are separated by the furnace grate; the combustion chamber above the furnace grate is divided by a middle fireproof plate into the left combustion chamber and the right combustion chamber; and each combustion chamber is provided with a feed port, and is additionally provided with a preheating water pipe and a filter device. With the adoption of the biomass particle hot-water boiler with the double combustion chambers, the problems of inadequate combustion, low surplus heat utilization rate of smoke, environment pollution by discharged smoke and the like in the existing combustion chambers are solved through the above manner; and the biomass particle hot-water boiler with the double combustion chambers has the advantages of sufficient combustion of fuel in a hearth, improved surplus heat utilization rate, and reduced environment pollution.

Description

technical field [0001] The invention relates to the technical field of heat source equipment, in particular to a biomass particle hot water boiler with double combustion chambers. Background technique [0002] Existing biomass pellet boilers generally include: furnace body, furnace, feeding device, fire grate, which is divided into upper and lower combustion chambers and ash chambers by the fire grate, and all use one combustion chamber, and biomass particles enter the combustion chamber from above the furnace. Combustion after chamber. The disadvantage of using this traditional single combustion chamber combustion method is that the thermal efficiency is low, and the biomass particles cannot be fully burned, which makes the energy utilization insufficient; and the biomass particles are transported to the combustion chamber from top to bottom, resulting in biomass Insufficient combustion of particles produces a large amount of dense smoke, causing serious environmental ...

AI Technical Summary

Problems solved by technology

[0003] The main technical problem to be solved by the present invention is to provide a biomass particle hot water boiler with double combustion chambers, which can solve the problems of insufficient combustion in the existing combustion chambers, low utilization efficiency of flue gas waste heat, and environmental pollution caused by exhausted flue gas.
