Biomass particle boiler with compact arrangement, small capacity and large output

Abstract

The invention relates to a biomass particle boiler with compact arrangement, small capacity and large output. The biomass particle boiler comprises an intelligent control system, a combustion chamber, a combustor, a smoke outlet, a primary fan, a secondary fan, an induced air fan, a deaerator, a heat exchange chamber, a bag type dust remover, a steam and water separator, a steam separating cylinder and a boiler water purifier, wherein the heat exchange chamber adopts a convection pipe bundle to exchange heat; the heat exchange chamber is separated into four areas from top to bottom, and spraying and blowing devices are arranged at the four areas. The biomass particle boiler has the advantages that by adopting the multi-surface surrounding type deaerator, under the condition of guaranteeing the combustion temperature in the boiler, the heat insulation thickness is reduced, and supplied water can be preheated; the combustion chamber is separated from the heat exchange chamber; the combustion chamber is arranged in a folding way, and a secondary air increasing type is adopted, so the complete combustion is guaranteed; the heat exchange chamber is separated into the multiple areas, so the heat exchange is complete on the basis of guaranteeing a clean pipeline, and the temperature of tail exhaust smoke is low; by adopting the bag type dust removal, the smoke flowing to the atmosphere is very clean; by adopting the compact type arrangement, the size of the whole boiler is minimum.

Description

technical field [0001] The invention relates to biomass energy equipment, in particular to a compact, small-capacity, and high-output biomass particle boiler. technical background [0002] At present, the situation of air pollution prevention and control is severe, and a large number of coal-fired boilers need to be replaced by clean energy for heating. Moreover, the biomass pellet boilers currently on the market have two problems: one is that the heat transfer per unit volume is poor, and the exhaust gas temperature Second, the existing biomass pellet boilers are incompletely combusted and will produce a large amount of dense smoke, which will have a certain impact on the environment; this invention mainly studies a biomass pellet boiler with high heat transfer performance and complete combustion. Contents of the invention [0003] The purpose of the present invention is to provide a compact, small-capacity and high-output biomass pellet boiler with high heat exchange per...
