Description

The gasification coal furnace

Technical field: the utility model belongs to burning and uses apparatus field, relates to a kind of gasification coal furnace.

Background technology: in the prior art, coal furnace, particularly civilian band heating water jacket's coal furnace, its jacket structure for water has two kinds of forms substantially: a kind of is individual layer water jacket shape, and a kind of is tubular heat exchanger shape, and the former heat energy utilization rate is low, easy dust stratification of the latter and easy to clean not, and complex manufacturing technology cost height; In addition, the burning of coal mode substantially all is that common upper strata is direct-fired, and promptly superposed burning zone directly burns with the air that is entered by its underpart, the up discharge of flue gas, its weak point is that the combustion space is little, incomplete combustion, efficient are low, and the coal number of times is frequent, Workflow's dust.

Summary of the invention:

The technical problem that solves: adopt double-layer water jacket and the ad hoc coal bin vaporizer structure of holding concurrently; change burning of coal mode and heating water jacket's structure; overcome the deficiencies in the prior art; improve burning of coal efficient and heat energy utilization rate; and easy to use, easy making, cost are low, are beneficial to environmental protection simultaneously.

Technical scheme:

The gasification coal furnace, have stone or metal plate for standing a stove on as a precaution against fire 1, shaft 2, base 3, liner 22, heat-insulation layer 23 and the corresponding attached parts that help, it is characterized in that: shaft 2 has double-layer water jacket, structure is as follows: have annular smoke-box 9 between inner water sleeve 6 and the outer water jacket 7, the inwall of inner water sleeve 6 is formed furnace chamber 8, two water jackets are by being interconnected connection dish 11 and communicating pipe 12, and are connected to water inlet 13 and delivery port 14; Be interconnected by the intercommunicating pore on the inner water sleeve 6 10 between furnace chamber 8 and the annular smoke-box 9; Annular smoke-box 9 has the outer hole 15 that connects of outside smoke evacuation.

Beneficial effect: double-layer water jacket, thermal efficiency height, dust stratification easy to clean; The coal bin vaporizer structure of holding concurrently can improve the burning of coal rate, reduces the coal number of times, help environmental protection; Easy to use, the parts replaceability is strong; Easily make, cost is low; Be particularly useful for vast rural area, promptly be applicable to heating, bathe and wash, can be used to heat up water again cook.

Accompanying drawing 4, C-C cutaway view;

The plan structure schematic diagram of the pallet 16 of the band fire grate 17 of accompanying drawing 5, base 3;

The specific embodiment: further explanation in detail in conjunction with the accompanying drawings.

The outer hole 15 that connects of annular smoke-box 9 is positioned on the connection dish 11, and complements one another with the mouth 5 that is positioned on the stone or metal plate for standing a stove on as a precaution against fire 1.

Connect hole 15 outward and have deflector 24 in a side of annular smoke-box 9.

It is supporting with furnace chamber 8 to have fire door 4 on the stone or metal plate for standing a stove on as a precaution against fire 1.

Base 3 is made up of two parts: pallet 16, fire grate 17 is housed on it, this fire grate 17 has the fixedly fixedly comb dish 34 of comb wing 35 of band, and the activity comb dish 36 of supporting band comb wing is arranged, simultaneously by rotating shaft 37 and body of heater outward action bars 38 be connected; For large-scale gasification coal furnace, then adopt the movable comb dish 36 of many covers, and by respective link mechanism hinge together; Have ash removing opening 20 with annular smoke-box 9 corresponding positions on the pallet 16, and supporting closure plate 21 is being arranged; Bearing 18 links together with pallet 16 closure, having accent fire and the ashpit 19 of holding concurrently of banking up a fire on it.

Stone or metal plate for standing a stove on as a precaution against fire 1, shaft 2, base 3 dismoutabilities connect as one.

Also have the coal bin vaporizer 25 of holding concurrently, supporting with fire door 4 and furnace chamber 8 on the stone or metal plate for standing a stove on as a precaution against fire 1, have cylindrical shell 26, blue dish 27, flame-observing hole 28, lid 29, handle 30; Also can be with water leg 31, filler 32 is arranged on it, simultaneously, have supporting pore 33 on the wall of cylindrical shell 26.

When installing and using, as required smokestack and exhaust opening 5 are linked together.

When being used for heating, to coal bin 25, the coals 39 of vaporizer of holding concurrently, can be for burning about ten hours; When band water leg 31, need regularly in it, to add water.

Principle and operating instruction:

Burning zone 40 gas fume after burning fully enter annular smoke-box 9 by intercommunicating pore 10 after the burning in furnace chamber 8, because the effect of deflector 24, flue gas is being complied with direction heat exchange from bottom to top after connect hole 15 outward by exhaust opening 5 discharges, and the water in the inside and outside water jacket is fully heated; Outside body of heater, stir action bars 38 by rotating shaft 37 drive activity comb dishes 36 and comb wing thereof and fixedly wing 35 relative motions of combing surely of the resistance on the comb dish 34 in good time, so ashes fall in the bearing 18, this moment, burning zone 40 descended, and hold concurrently coals 39 in the cylindrical shell 26 of vaporizer 25 of coal bin move down automatically under the gravity effect and give to replenish; Regularly can remove dust stratification in the annular smoke-box 9 by ash removing opening 20.

Coal bin hold concurrently coal 39 in vaporizer 25 cylindrical shells 26 under the effect of furnace chamber 8 combustion high temperature by destructive distillation, the gas that distillates enters furnace chamber 8 burnings, and the coal 39 after the destructive distillation constantly carries out replenishing automatically to burning zone 40, so can greatly improve burning of coal efficient; When band water leg 31, water in it can be produced steam by the heating of the high-temperature gas in the cylindrical shell 26, and enter in the cylindrical shell 26 by pore 33, and then produce water-gas in furnace chamber 8 internal combustion by scorching hot burning zone 40, not only burning of coal efficient can be further improved, and the heat supply can be increased.

After the taking-up coal bin is held concurrently vaporizer 25, can manipulate as common coal furnace, and can heat up water by fire door 4 and cook.
