The specific embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Among Fig. 1 ~ Fig. 4, comprise that operating platform 1 behind the stove, inclined ladder 2, chimney 3, flue gas butterfly valve 4, air heat exchanger 5, furnace side dial material platform 6, stokehold hot-air duct 7, body of heater 8, stokehold heating gas pipeline 9, water seal dust arrester 10, stokehold water collector 11, mixed gas producer 12, blower fan 13, burner 14 etc.
As shown in Figure 1, the present invention is a kind of energy-saving inclined-bottom heating furnace, comprises body of heater 8, and the rear portion of body of heater 8 is furnished with chimney 3, blower fan 13 and mixed gas producer 12; The front portion of body of heater 8 is furnished with gas burner; The both sides of body of heater 8 are furnished with the furnace side and dial material platform 6, and the afterbody of body of heater 8 is equipped with operating platform 1 behind the stove, and operating platform 1 links to each other with ground through inclined ladder 2 behind the stove.The front portion of body of heater 8 also is furnished with stokehold water collector 11.
Mixed gas producer 12 is that gasifying agent is gasificated into coal gas with solid fuel (coal or coke) with air and steam, for heating furnace provides gaseous fuel.Mixed gas producer 12 gasification principles are reasonable, equipment simple, small investment, and fuel cost is low.The heating gas that mixed gas producer 12 produces communicates with stokehold heating gas pipeline 9 through escape pipe and water seal dust arrester 10 backs, and water seal dust arrester 10 can be removed the dust impurity in the coal gas, and the coal gas fuel of cleaning is provided.Mixed gas producer 12 and water seal dust arrester 10 all have two covers, communicate with stokehold heating gas pipeline 9 after the escape pipe parallel connection of two cover mixed gas producers 12.
Like Fig. 1, shown in Figure 2; The afterbody of body of heater 8 has the high-temperature flue gas outlet; The high-temperature flue gas outlet communicates with chimney 3 through pipeline; Pipeline between high-temperature flue gas outlet and the chimney 3 is provided with air heat exchanger 5, and the pipeline between air heat exchanger 5 and the chimney 3 is provided with flue gas butterfly valve 4, the flow of flue gas butterfly valve 4 scalable flue gases.Like Fig. 1, shown in Figure 4, blower fan 13 provides air for body of heater 8, and the wind pipe of blower fan 13 links to each other with stokehold hot-air duct 7 through air heat exchanger 5 backs.Air heat exchanger 5 comes preheating to lead to the air of burner the heat recovery of high-temperature flue gas, but energy savings.
As shown in Figure 3, gas burner comprises the many groups burner 14 perpendicular to body of heater 8 center lines layout that is arranged on the body of heater 8 anterior tops, and every group of burner 14 comprises two burners 14 that are symmetrical in body of heater 8 center lines layout.Each burner 14 links to each other with stokehold hot-air duct 7 that is arranged in body of heater 8 tops and stokehold heating gas pipeline 9.Burner 14 arranges that like this temperature in the body of heater 8 is even, and the thermal efficiency is high.
