Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further details:
A kind of special clean combustion furnace of moulded coal, as Figure 1-3, it includes body of heater 2 to structure, is provided with combustor 3 in described body of heater 2 With the fire grate 13 being positioned at below combustor 3, bottom the body of heater 2 below fire grate 13, it is provided with cleaning door 4, described body of heater 2 top It is provided with outlet flue 1: the side of described body of heater 2 is provided with the feed bin 5 being connected with combustor 3, between described feed bin 5 and combustor 3 The feed pipe 6 being provided with the special feed auger of moulded coal by inside is connected, and described feed auger is driven by feeding motor, described smoke Being provided with air-introduced machine in the pipeline that mouth 1 connects with combustor 3, described charging motor, air-introduced machine are electrically connected with intelligent control unit respectively Connect.
Body of heater 2 above combustor 3 is from inside to outside provided with inner bag flaggy 15 and outer gallbladder flaggy 16, described inner bag flaggy 15 It is provided with water jacket 17 between the medial wall of lateral wall and outer gallbladder flaggy 16.
The inner chamber of described inner bag flaggy 15 is provided with the burning backhaul that upper end connects, lower end connects with combustor 3 with outlet flue 1 Passage, described burning return pass includes overdoing storehouse 7 and storehouse of overdoing under being positioned on the left of combustor 3 in overdo storehouse 10, upper left of upper right 12, upper right overdo storehouse 10 and under overdo between storehouse 12 and upper left overdo storehouse 7 and under overdo between storehouse 12 respectively by crossing fire tube 11 connections, storehouse 7 is overdoed in upper left and upper right overdoes and is provided with dividing backhaul baffle plate 9 between storehouse 10, overdoes storehouse 7 in described upper left Connect with outlet flue 1.
Described combustor 3 be arranged over endothermic tube 14, described endothermic tube 14 is welded on water jacket 17 and in endothermic tube 14 Water connect with the aqueous phase in water jacket 17.Endothermic tube 14 absorbs the heat of combustor 3 fuel combustion, and water temperature inside rises, water Water temperature in set 17 also and then rises, and the thermal efficiency improves.
The sidewall of combustor 3 is provided with oxygen enhanced gasification passage, and described oxygen enhanced gasification passage supplies with the interior thorax of setting in body of heater 2 Oxygen import 8 is connected, and described interior thorax oxygen supply import 8 is connected with the burner hearth oxygen supply import 19 being arranged on body of heater 2, described interior thorax Oxygen supply import 8 is connected with extraneous aerator by pipeline, and described aerator electrically connects with intelligent control unit.
The PLC control unit finishing writing moulded coal dedicated program is electrically connected with charging motor, aerator, air-introduced machine respectively, it After switch on power, start whole combustion furnace work.Under the control of intelligent control unit, open charging motor, charging motor rotation Turn the special feed auger of the moulded coal in drive feed pipe 6 to rotate, by the moulded coal in feed bin 5 under the control of intelligent control unit, The combustor 3 sent in body of heater 2 by moulded coal by its feeding speed set burns.In Coal Briquettes Combustion, according to type The character of coal self, intelligent control unit controls the air quantity of aerator, and the top of body of heater 2 inner combustion chamber 3 from inside to outside sets There is the medial wall of inner bag flaggy 15, outer gallbladder flaggy 16 and heat-insulation layer 18, the lateral wall of described inner bag flaggy 15 and outer gallbladder flaggy 16 Between be provided with water jacket 17.Such structural thermal insulation is effective, it is ensured that moulded coal fully and completely burns in combustor 3, to release Big heat, is effectively improved the thermal efficiency.
Some flue gases unavoidably can be produced, owing to flue gas and flame are pumped to by the effect of air-introduced machine during Combustion of Mould Coal Outlet flue 1, flue gas and flame are drawn into storehouse 12 of overdoing in combustor 3, then through fire tube 11 enter upper right overdo storehouse 10 or Upper left overdo storehouse 7, flue gas and flame under overdo storehouse 12, cross fire tube 11, upper right and overdo storehouse 10 and overdo and pass in storehouse 7 in upper left, Some soot dust granules increase the chance of its second-time burning when of circulating through wherein, and heating surface area also increases.Set up Burning return pass can improve the thermal efficiency of moulded coal.
The oxygen enhanced gasification passage arranged on the sidewall of combustor 3 is connected with interior thorax oxygen supply import 8 and burner hearth oxygen supply import 19 Logical, described interior thorax oxygen supply import 8 and burner hearth oxygen supply import 19 are all connected with aerator, in the combustion process of moulded coal, by air blast The required oxygen of fuel supply in combustor 3 given by machine by interior thorax oxygen supply import 8 and burner hearth oxygen supply import 19.To reach intelligence control The purpose of fuel combustion temperature processed.
Intelligent control unit, according to body of heater 2 inner mold burning of coal situation, automatically controls the rotating speed of feeding motor, air-introduced machine and The air force of aerator, finally realizes energy-conserving and environment-protective, the purpose of discharged at lower temperature.
