Cyclone boiler

Abstract

The technology discloses a cyclone boiler which comprises a furnace wall, a blast blower and a grain feeding auger, wherein the grain feeding auger is connected to the part above the middle part of the furnace wall; a furnace door and an ash outlet are arranged at the lower end of the furnace wall; a smoke discharge tube is connected with the top of the furnace wall; a fire grate is near the bottom part; a furnace wall air flue is arranged along the furnace wall; more than two blast pipes the tops of which are sealed and communicated with the furnace wall air flue are attached to the furnace wall above the furnace wall air flue; the blast pipes are vertically arranged; a ventilating hole is formed at the same side of axes of the blast pipes towards the direction of the furnace wall from the interior of the boiler, so eddy is formed inside a hearth by the air blown from the ventilating hole; the fire grate is arranged below the furnace wall air flue, and an air outlet is arranged at the inner side of the furnace wall air flue. The technology has the beneficial effects that the structure is simple; the operation is convenient; oxygen supply can be further reinforced; the ignition of particles inside the auger can be avoided at high temperature after feeding is stopped; thermal radiation of the hearth can be reduced to the maximal extent; oxygen of the hearth can be supplied for the second time; and the fuel burns more fully, and the thermal efficiency of the boiler is high.

Description

technical field

[0001] The technology relates to a cyclone boiler. Background technique

[0002] The combustion of biomass pellets and briquetting boilers in traditional fixed grates uses induced draft fans to draw air, and there is also a way to increase the blower to blow air under the grate. This kind of combustion grate requires a certain gap to meet the needs of biomass molding fuel. Oxygen supplementation during the combustion process, the fuel must not coke or completely cover the fixed grate, otherwise black smoke will appear, and if it is not handled in time for a long time, the furnace will go out. After a long time of normal use, a thick layer of tar will form on the furnace wall, which will affect the heat absorption of the boiler and greatly reduce the thermal efficiency of the boiler. Chinese technical patent (patent number: 01264814.0) discloses a vertical smokeless combustion boiler, including the boiler body, base, ventilation equipment, grate, combustion c...
