Background technology

At present, known civil boiler is of a great variety, and is various.Check in the boiler of only declaring patent through patent retrieval and just reach thousands of.For a long time, the boiler manufacturing industry is often installed device for abatement of smoke and dust, economizer, wet type device for abatement of smoke and dust etc. for environmental protection, energy-conservation on boiler.Though reduced dust pollution like this, and consumed great amount of water resources, and with secondary pollution; The boiler that has adopted secondary or three times air-supply, increase heating surface area and just burn, anti-modification measures such as burning, but how not ideal enough general effect is, especially the vertical boiler that has a large capacity and a wide range, smoke contamination and the phenomenon that wastes energy are more serious, although people carry out multiple transformation to existing boiler, environmental pollution height, the problem that the thermal efficiency is low and the second investment is bigger also still exist.

Summary of the invention:

1. the technical problem that will solve

The purpose of this utility model provides a kind of kiln formula revolution gasification fired boiler, coal-fired in kiln formula revolution combustion chamber after pre-burning, decomposition, half gasification, entering gasification combustion chamber through blast tube burns away, make it sufficient combustion two, under the effect of tertiary air, reach no flue dust discharging, free from environmental pollution, energy savings, thermal efficiency height.

2. technical scheme

The purpose of this utility model is to realize with following technical scheme: turn round gasification fired boiler by fire grate, burner hearth, gasification combustion chamber, spray wind is chewed, ajutage is formed kiln formula, being provided with a top in a side of boiler has coal filling hole, bottom that the kiln formula revolution combustion chamber of burner hearth, main fire grate and secondary fire grate is arranged, between burner hearth and gasification combustion chamber, be provided with secondary air channel, blast tube and coal gas overflow explosion stack, be provided with several spray wind and chew on the wallboard around the gasification combustion chamber, fire grate is turnable.

Have the secondary air channel that several angle of declinations are 7-15 ° air nozzle, be installed in the top of blast tube, air nozzle is blown to oblique below by warm air curtain, when being the imflammable gas oxygen supply, suspended particulate substance in the imflammable gas is suppressed, it is fully burnt.

Several spray wind around the gasification combustion chamber on the wallboard are chewed and are all pressed eccentric shaft direction setting in opposite directions, and its eccentric angle is 5-20 °, and each sprays the half garden shape air main that wind chews respectively by the both ends open in inferior airduct and the annular matching air box and is connected.Help tertiary air stream like this, unburned combustible is further burnt in the indoor generation rotation of gasification, and combustion.

Respectively be provided with the main fire grate and the secondary fire grate of several butt taper disintegrating slag columns, be installed on the fire-grating frame by bearing, be connected by gear between the major and minor fire grate, be provided with the leverage that gear is rotated in the end of main fire grate, when main fire grate rotates, secondary fire grate under the drive of gear also along with rotation, reach remove slag, the purpose of disintegrating slag.

3. beneficial effect

The beneficial effects of the utility model are to realize that in stove collection burning, smoke elimination, dedusting are one, make full combustion of fuel, reduce the pollution of flue dust to environment, and safety anti-explosive, thermal efficiency height, energy savings.
