Description

The biomass massive Fuel Furnace

Technical field:

The utility model relates to a kind of combustion furnace, especially a kind of biomass massive Fuel Furnace.

Background technology:

The biomass block technology is through pulverizing, being compressed into hard-packed moulding stick (piece) or granular fuel after the drying with agricultural waste material such as loose all kinds of straws, rice husk, peanut shell and saw foam.At present, domestic existing how tame postgraduate's material former, and have spiral, fluid pressure type and granule-forming machine to go on the market, technology also is mature on the whole.But the biomass moulding piece is used for charing more at present.

Present biomass fuel boiler mainly is to be the fluidized-bed combustion boiler of raw material with the straw after pulverizing, the granular fuel stove that Shanxi is ten thousand, and main is the fireplace and the life use stove of fuel with the shaped granule.Becoming the piece piece with living beings is that the boiler of fuel all is blank at present in China and even the world.What have transforms with coal-fired pot, but finds in the process of operation, forming blocks in combustion process, combustion instability and exist slagging scorification and the floating dust phenomenon; Floating dust can purify by deduster, but slagging scorification will seriously influence exerting oneself of boiler.

The utility model content:

The purpose of this utility model provides a kind of slagging scorification of stove in combustion process and biomass massive Fuel Furnace of floating dust problem of solving.

The technical solution of the utility model is:, a kind of biomass massive Fuel Furnace, comprise water storage device and burner, water storage device is made of the outer courage of annular and the annular inner bag of two mutual sheathing, link by water pipe between them, a capping is arranged at the top of courage outside annular, one exhaust opening is arranged in capping, outside annular, there are this flue of a flue and exhaust opening to link between courage and the annular inner bag, the burner hearth that burner is formed by the internal chamber wall of annular inner bag, fire grate that seamless steel pipe is made and ash hole constitute, fire grate and annular inner bag link and are divided into burner hearth up and down that two combustion chambers have a charging aperture on a side of combustion chamber, have a breast hole on the side below the fire grate, the lateral surface upper and lower side of courage respectively has a delivery port and water inlet outside annular.

Have annular secondary air mouth in the burner hearth below fire grate, fire grate is arranged above ash hole.

Outer courage of described annular and annular inner bag are cylindrical.

Below breast hole on the combustion chamber, have one and see burner.

The spacing of fire grate is greater than the spacing of fire grate.

Fire grate is to the lopsidedness of charging aperture.

UNICOM's water pipe between outer courage of annular and the annular inner bag is the state that is staggered up and down.

Water pipe tilts from inside to outside.

This body of heater adopts the anti-combustion system that burns of two courages to burn, can effectively solve the floating dust problem in its combustion process, in order further to reduce the floating dust amount, flue between two courages is widened, its flue gas flow rate is reduced, flue is designed to the S type, when making flue gas up, form S road warp, increase the resistance of flow of flue gas, simultaneously the thermal efficiency is further improved thereby further reduce the floating dust amount.

This stove adopts the second-time burning mode to burn, and makes the forming blocks continuous burning that partly gasifies, thus make biomass briquette in burner hearth fully burning improved the thermal efficiency of stove.

In order to solve the slagging scorification problem, on the side below the fire grate, have a breast hole, can clear up the slagging scorification on the fire grate by this mouthful.The use of this stove will promote straw shaped applying.The real problem that solves peasant's combustion (of oil) insitu straw is alleviated simultaneously and is solved some areas energy starved problem.
