In the accompanying drawing, 1 for body of heater, 2 for burner hearth, 3 for Heat Room, 4 for air inlet duct, 5 for air blast A, 6 for interior cycle flue, 7 be that flue, 8 for blower B, 16 for outer circulation flue, 17 for auxiliary flue, 18 is deduster for advancing oxygen channel B, 14 for oxygen feeder, 15 for advancing oxygen passage A, 13 for hot-air mouth, 12 for external hot air road, 11 for interior hot-flow flue, 10 for outlet flue, 9.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in Figure 1, the utility model is the special-purpose heat supply stove of a kind of coal-burning, mainly form by body of heater 1, be divided into two parts that do not communicate in the body of heater 1, top is Heat Room 3, the bottom is the interior cycle flue 6 that is provided with spiral fashion so in burning type burner hearth 2. Heat Rooms 3, the outlet flue 8 of interior cycle flue 6 stretches out body of heater 1 upper end. and as shown in Figure 2, the periphery of described burner hearth 2 and Heat Room 3 is enclosed with the vertical external hot air road 10 of annular vertical air inlet duct 4, annular, the vertical vertical interior hot-flow flue 9 of crossing flue 7, annular of annular from outside to inside successively; As shown in Figure 1, described air inlet duct 4 lower ends are air inlet, and the upper end is communicated with Heat Room 3, and air inlet duct 4 is provided with air blast A5, is used to increase intake; The upper end in hot-flow flue 9 and external hot air road 10 is communicated with Heat Room 3 respectively in described, external hot-air mouth 11 after the lower end communicates, and hot-air mouth 11 outside heat air deliveries are used for outside heating; Described flue 7 lower ends of crossing communicate with burner hearth 2, and the outside that the upper end is communicated with interior cycle flue 6. burner hearths 2 also is provided with an oxygen feeder 14 with exterior, and oxygen feeder 14 is provided with blower B 15; Oxygen feeder 14 is communicated with burner hearth 2 tops by advancing oxygen passage A12, is used to provide burning oxygen.
For reducing the exhaust temperature of flue gas, also be provided with an outer circulation flue 16 that spirals outside the body of heater 1, this outer circulation flue 16 communicates with the outlet flue 8 of body of heater 1 upper end.For increasing the EAT of Heat Room 3, improve the thermal efficiency of boiler, the air inlet of described air inlet duct 4 is positioned at this outer circulation flue 16 places, by the temperature of outer circulation flue 16 preheating air intakes.
For avoiding fire extinguishing in burner hearth 2 burnings, and the maintenance burning of burner hearth 2 when guaranteeing banking fire, described oxygen feeder 14 also be provided with one communicate with burner hearth 2 bottoms advance oxygen channel B 13, advance oxygen passage A12 and advance oxygen channel B 13 to be provided with into oxygen valve, be used to regulate oxygen feeding amount.Advance oxygen passage A12 and be used for the heating burning of burner hearth 2, advance oxygen as secondary; Maintenance burning when advancing oxygen channel B 13 and being used for burner hearth 2 banking fires.For increasing the discharging intensity of flue gas, burner hearth 2 tops also are communicated with an auxiliary flue 17 simultaneously, and this auxiliary flue 17 passes Heat Room 3, external outer circulation flue 16; Body of heater 1 outer auxiliary flue 17 is provided with a deduster 18.
When heating is used, open into oxygen passage A12, blower B 15 oxygen supply in burner hearth 2, oxygen is provided and delivered downwards, forms reverse burning, and flue gas is descending, advance oxygen mixed combustion with secondary, outwards discharge through interior cycle flue 6, outer circulation flue 16 by crossing flue 7, heat exchange and cooling in the discharging reduce the black smoke discharging again.Since be reverse burning, sufficient combustion, energy-conservation, and can use bituminous coal.Open air blast A5 simultaneously, enter Heat Room 3 through air inlet by air inlet duct 4, carry out heat exchange, produce hot-air with interior cycle flue 6 through the air of outer circulation flue 16 preheatings; Hot-air respectively by interior hot-flow flue 9 and external hot air road 10 and and the flue 7 of crossing between the two carry out heat exchange once more, the hot-air of formation is discharged by hot-air mouth 11, outwards heating.Because air inlet duct 4 is arranged on the periphery in external hot air road 10, external hot air road 10 can be to the air secondary preheating in the air inlet duct 4, thereby improves the thermal efficiency.During the banking fire burning, close into oxygen passage A12, open into oxygen channel B 13, keep a small amount of oxygen feeding amount, burner hearth 2 banking fires burning, the flue gas of generation is discharged into outer circulation flue 16 by auxiliary flue 17.
