Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, horizontal backfire coal-burning boiler easy to use.
In order to address the above problem, the utility model by the following technical solutions:
A kind of horizontal backfire coal-burning boiler comprises inside of boiler and overcoat, and inside of boiler comprises gas generating chamber, combustion chamber and secondary furnace, boiler adopts the coal-fired mode of backfire, boiler furnace is horizontal, and upper of furnace body is provided with air pipe, outlet pipe, chimney and shoot door, and the bottom is provided with return pipe; Form water jacket between inside of boiler and the overcoat, the boiler appearance is provided with heat-insulation layer.
Be provided with coal store in the described gas generating chamber, the body of heater sidepiece is provided with coal filling hole and air inlet, and coal filling hole and air inlet all have the air channel, and coal filling hole and air inlet are communicated with coal store respectively; The coal store below is provided with fire grate, and the body of heater of fire grate below is provided with breast hole.
Be provided with water jacket partition in the described combustion chamber, water jacket partition separates the combustion chamber, and the combustion gas path is two S type trends;
Be provided with a plurality of convection tubes in the described secondary furnace.
Compared with prior art, the beneficial effects of the utility model are:
Easy to use, fuel consumption is low, prevents that effectively heat runs off, and reduces the burning total amount, alleviates the pollution of waste gas to environment, makes environmental protection and the energy-conservation purposes that reach two receipts.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
A kind of horizontal backfire coal-burning boiler, comprise inside of boiler 18 and overcoat 19, inside of boiler 18 comprises gas generating chamber 6, combustion chamber 7 and secondary furnace 10, boiler adopts the coal-fired mode of backfire, boiler furnace is horizontal, upper of furnace body is provided with air pipe 15, outlet pipe 16, chimney 11 and shoot door 8, and the bottom is provided with return pipe 13; Form water jacket 17 between inside of boiler 18 and the overcoat 19.Be provided with coal store 4 in the gas generating chamber 6, the body of heater sidepiece is provided with coal filling hole 5 and air inlet 3, and coal filling hole 5 and air inlet 3 all have the air channel, and coal filling hole 5 and air inlet 3 are communicated with coal store 4 respectively; Coal store 4 belows are provided with fire grate 2, and the body of heater of fire grate 2 belows is provided with breast hole 1.
Wind at first enters the top of coal store 4 through the air channel, make to form backfire under the wind direction, and wind is by breast hole 1 time, and some enters in the stove from breast hole 1, forms secondary air, by multiple spot air distribution and backfire, makes fuel reach the purpose of completing combustion; Be provided with several water jacket partitions 9 in the combustion chamber 7, combustion chamber 7 is separated, improved combustion efficiency so greatly, make the combustion gas path be two S type trends; Be provided with a plurality of convection tubes 12 in the secondary furnace 10, make full use of flue gas like this, increase the thermal efficiency, be provided with heat-insulation layer 14, prevent that effectively heat runs off, and promptly reduces fuel consumption and has improved the thermal efficiency again in the boiler appearance.
