Porous type far infrared burner and far infrared guard, baffle plate will have certain thermal shock resistance and higher radiation intensity, and enough flue gas circulation areas also will be arranged.Set up air-introduced machine at exhaust opening in case of necessity.
Collection smoke box and some times smoke pipes will have certain cross-sectional area, in time discharge to guarantee waste gas.
One end of super heat-conductive pipe absorbs heat in collection cigarette clean room, and the other end dispels the heat in boiler water.The shell inwall is arranged some to the magnetic antiscale device, reduces scale hazard.Boiler surfaces has the temperature layer, reduces radiation loss.
During work, coal gets into vaporizer from coal bunker and produces coal gas and coke, and get into the combustion chamber and burn jointly, smokeless combustion, the slag after the burning is discharged from the slag notch of boiler back.A little combustible and flying dust get into collection cigarette clean room with high-temperature flue gas to carry out three burnings of secondary again and purifies; Far infrared device helps catalysis; The waste gas that is produced gets into the collection smoke box by returning smoke pipe, discharges from exhaust opening, need not chimney; Just can accomplish the toxic emission after the fuel combustion, reach save material, purpose such as environmental protection and energy saving.
Advantage of the present invention: multiple new and high technology organically combines, and flue dust, the inner digestion of combustible are purified, and realizes the utilization of coal clean and effective, and it is colourless dustless to discharge fume, non-secondary pollution, and environment protecting is good; Heating surface area is big, reduces each item heat loss, and the thermal efficiency can reach 75%-85%, improves 20%-30%, energy savings than conventional boiler 55%; Need not chimney, the minimizing expense is practiced thrift multiple resource; Need not the used great lot of water resources of wet dedusting, using water wisely; Lower than oil-burning gas-fired boiler and anthracite-fired boiler cost, manageability is increased income and economized on spending, and the automatic and mechanical operation is carried out production strictly in line with rules and regulations.
