Abstract

The utility model relates to a high efficient, quick heated and smokeless vaporization coal-saving furnace, which pertains to the boiler. A furnace base 1 is movably connected with a furnace grate 2, an outer water jacket 3 is fixedly connected with the furnace base 1; the lower end of a vaporization grate 4 is connected with the outer water jacket 3, and the upper end of the vaporization grate is connected with an inner water jacket 16; the upper part of the inner water jacket is connected with the outer water jacket via an inner and outer water jacket communicating pipe 5; the lower part of a coal storage storehouse is a first combustion chamber 8; the space between the outer water jacket and the inner water jacket is provided with a second combustion 9; the top end of the middle of the second combustion chamber has an outlet flue 15. The utility model has the advantages that, the structure is novel, the second combustion chamber is high, a secondary ventilation door can supplement oxygen; the utility model replaces draft fan, air blower, etc., which has good coal combustion and high heat efficiency; as the soot is burned off in the second combustion chamber, and the exhausted air is smokeless and dustless, the pollution of the atmosphere is reduced, thus conforming to the demands of environmental protection.

Description

The highly efficient quick heating coal-saving stove of smokelessly vaporizing

Technical field the utility model belongs to boiler.

The existing vertical circular boiler of background technology bottom is fire grate entirely, and the outside is a water layer, and the centre is a flue.Pyrotechnics passes through around flue, and heating surface area is little, and the speed that pyrotechnics passes through is fast, and rate of heat exchange is low, and water heats up slow, black smoke is big, and is serious to atmosphere pollution, also will use hair-dryer, air blast and air-introduced machine, also will use deduster, cause coal consumption big, make power consumption big, noise is big.

Summary of the invention the utility model provides a kind of highly efficient quick heating coal-saving stove of smokelessly vaporizing, and is big to solve energy consumption, the big and big problem of flue dust of noise.The technical scheme that the utility model is taked is: flexibly connect fire grate 2 on the stove seat 1, outer water jacket 3 is fixedlyed connected with stove seat 1, vaporization grate 4 lower ends connect outer water jacket 3, the upper end connects inner water sleeve 16, this inner water sleeve top was connected with outer water jacket with inside and outside water jacket communicating pipe 5, there are two outlet pipes 12 outside, outer water jacket top, 13 1 blow-off pipes 14 of two return pipes are arranged at outer water jacket bottom, dog-house 6 is positioned at upper of furnace body, communicate with coal store 7, the coal store bottom is first combustion chamber 8, it between outer water jacket and the inner water sleeve second combustion chamber 9,3 secondary oxygen supply doors 17 are arranged on this second combustion chamber, there is outlet flue 15 on this top, middle part, second combustion chamber, in bottom, first combustion chamber one skimming door 10 is arranged, and three ash doors 11 are arranged around the stove seat.During use, inside and outside water jacket is full of water, adds coal from dog-house, and air also enters from dog-house, and coal burns for the first time in bottom, first combustion chamber, and flue dust enters second combustion chamber by the vaporization grate, burns away, and waste gas is discharged from exhaust opening.

Advantage of the present utility model is: novel structure, the second combustion chamber height, the all right supplemental oxygen of twice aeration door, substituted air-introduced machine, air blast etc., coal combustion is good, thermal efficiency height, flue dust is burnt in second combustion chamber, smokeless and dust free in the gas of discharging reduces the pollution to atmosphere, compliance with environmental protection requirements.
