Background

China is a large-resource country and a weak-resource country, the coal consumption is continuously increased along with the further development of the urbanization process, and the resource problem needs to be solved urgently. The biomass energy resources in China, such as straws, peanut shells, rice husks, wood chips and the like, are very rich, and the energy problem can be relieved to a certain extent. However, the existing biomass boiler has the problems that fuel is not sufficiently combusted, a large amount of combustible gas components are discharged into the atmosphere to cause serious energy waste and the like, and harmful gas can be released to cause overhigh emission concentration of flue gas and cause environmental pollution.

Disclosure of Invention

The invention aims to provide a biomass clean heating boiler, which can be a combustor capable of lengthening flame stroke and prolonging the combustion time of volatile components and fixed carbon, thereby fully utilizing biomass energy.

In order to achieve the purpose, the invention provides the following technical scheme:

a biomass clean heating boiler comprises a feeding bin, a furnace body, a chimney, a smoke outlet, an air distribution box, an ash falling bin, a front combustion chamber and a rear combustion chamber, wherein the feeding bin and the chimney are respectively arranged on a furnace body platform; a plurality of hot water pipes are arranged in the front combustion chamber connected with the feeding bin, a plurality of hot water pipes are arranged in the rear combustion chamber, and an ash falling bin is arranged below the rear combustion chamber; and a heat storage surface is arranged in the front combustion chamber and used for forcibly prolonging the combustion time of volatile matters and fixed carbon.

Furthermore, the front and the rear combustion chambers are divided into two parts by a metal partition plate, and the metal partition plate is communicated with the furnace body.

Furthermore, the output hot air of the air distribution box respectively enters the front combustion chamber and the rear combustion chamber through the air inlet and the secondary oxygen adding pipe.

Further, the ash falling bin is provided with an ash cleaning door.

Furthermore, the chimney is internally and transversely surrounded by a water inlet and outlet pipe, so that the waste heat of the boiler can be absorbed conveniently.

The invention has the beneficial effects that:

according to the biomass environment-friendly boiler, the heat storage surface is arranged in the fuel chamber, so that the heat exchange area is increased, the heat transfer is enhanced, the burning time of volatile fixed carbon is prolonged, the boiler efficiency is improved, the incomplete fuel burning condition is improved, the flame stroke is long, the fuel burning is full, black smoke is reduced, and the atmospheric pollution is reduced.
