Description

Two chambers disjunctor coal transforms the coal gas environment friendly energy-saving ordinary pressure water-boiling boiler

Technical field the utility model relates to a kind of large-scale civilian normal-pressure boiler, is the boiler of a kind of two large-scale combustion chamber disjunctors and second gasification specifically.

The at present civilian coal commentaries on classics gas normal-pressure boiler of background technology does not have large-scale, gives about 20,000 square meters and heats, with a boiler, fire grate is big, and burner hearth is dark, inconvenient operation, and big with two boiler floor spaces, many costs of boiler corollary equipment height, operation and stove are pretty troublesome.

The summary of the invention the purpose of this utility model is to provide a kind of pair of chamber disjunctor coal to transform the coal gas environment friendly energy-saving ordinary pressure water-boiling boiler, its sufficient combustion, and thermal efficiency height, energy-conserving and environment-protective, and floor space is little, corollary equipment is few, reduces the large tracts of land heat cost.

Technical scheme of the present invention is as follows:

This boiler is by body of heater, water jacket, the staggered heat exchange dividing plate, the heat-exchange tube that are communicated with water jacket, entery and delivery port, chimney, gas generating chamber, combustion chamber, and space for collecting ashes in a stove constitute; Two bodies of heater arranged side by side are arranged, the centre of two stoves is a water jacket, its top outlet flue also connects chimney together at the body of heater top, two body of heater front portions are opened shoot door from top to bottom respectively, observe door, are filled out ort, clean-out door, body of heater inside a plurality of above-mentioned heat exchange dividing plates that are staggered, bottom of furnace body is the tubulose fire grate of water flowing, fire grate is divided into the steam air jet pipe, this pipe connects the steam generator of dress in the gas generating chamber, and this generator is connected with the water jacket of body of heater through pipe; Be followed successively by combustion chamber, Heat Room above the gas generating chamber, the back of gas generating chamber and combustion chamber connects igniting chamber, and there is fire grate this chamber, fills out ort, shoot door, ventilating opening, cyclone, and gas generating chamber is communicated with the combustion chamber through igniting chamber; Be space for collecting ashes in a stove below the combustion chamber, space for collecting ashes in a stove has breast hole and gravity-flow ventilation mouth.

Above-mentioned heat-exchange tube all is angle with level.

Above-mentioned igniting chamber has fire-resistant combustion-supporting baffle plate.

Above-mentioned steam generator is contained in the rear portion of combustion chamber, is a casing, and puff prot is arranged at its top, the steam air jet pipe of this mouthful under pipe even fire grate, and steam generator has the water inlet that is connected with outer water supply tank, and the scale removal inspection socket is arranged at the bottom.

The invention has the advantages that: 1, this boiler disjunctor, merge two boilers, two boiler attendances characteristics are easily arranged, littler than two boiler floor spaces again, corollary equipment is few, saves cost.2, energy-conservation, the jet gas generating chamber that enters of this stove steam generator, fuel gas such as water-gas are regulated air intake through the igniting chamber ignition through cyclone, burn in the combustion chamber, make the more abundant burning of fuel, and thermal efficiency height is than similar boiler energy-saving 50%.3, environmental protection and energy saving, the heat exchange dividing plate that is staggered is more, makes the flue gas discharge path complications of body of heater inside, slows down mass rate of emission, reduces smog discharge temperature, after testing, smog discharge temperature about 56 degree, smoke dust discharge concentration 28.67mg/Nm ^3,,Other boiler emissions are about 188 degree, and heat is fully absorbed by water jacket, heat exchange dividing plate, heat-exchange tube, and flue gas fully burns simultaneously, and discharging makes dust emissions reduce slowly, and the graininess dust overwhelming majority is stayed in the body of heater, and is environmental.4, the heat-exchange tube of certain gradient is accelerated the water circulation, helps rapid intensification.Steam generator is connected with furnace water jacket, and the water that enters generator is hot water, and it is fast that steam is produced.Steam pipe leads under fire grate, and space for collecting ashes in a stove need not add water.5, because of quick heating, circulation is fast, and this pot is with 20,000 square meter heating areas, only uses circulating pump, without air blast, air-introduced machine, cleaner, reduces the heating cost.6, the rural area can make the peasant warm oneself, light stove convenient, healthy improving the quality of living without single household with this boiler implementation central heating among a small circle.
