Abstract
The utility model relates to a reverse burning heat pipe boiler with double grates, which belongs to the technical field of vertical boilers for domestic use. The utility model is composed of a boiler body (20), a boiler liner (17), a main smoke pipe (2), a heat pipe (19), a water cooling interval (15), a water pipe grate (13) and a grate (8), wherein, a preheating chamber is formed between the water cooling interval and the water pipe grate; the lower part of the boiler liner is provided with a combustion chamber, and the upper part is provided with a heat exchange chamber; fire pipes (6) are arranged around the boiler liner. The utility model has the advantages of little exhaust pollution and higher thermal efficiency, and is widely suitable for units of enterprises and institutions, hotels, factories, etc.
Description
The utility model relates to a kind of civilian vertical boiler, exactly is double grate counter-burning type heat pipe boiler.
The minitype vertical type fire tube boiler is widely-used in China town and country, and this boiler thermal output is on the low side, and exhaust smoke exceeds standard, and is one of urban atmospheric pollution principal element, and the power economized boiler of useful adopting heat pipes for heat transfer to improve the thermal efficiency, reduced fuel consumption in recent years.But exhaust pollution fails to improve; Insufficient because of burning, flue dust sticks to heat pipe outer wall, forms the barrier layer, and heat transfer efficiency is descended, and is difficult to produce a desired effect.
The purpose of this utility model is the deficiency at prior art, proposes a kind ofly can reduce exhaust pollution, can keep the double grate counter-burning type heat pipe boiler that serves many purposes of higher thermal efficient again.
The purpose of this utility model is achieved in that
A kind of double grate counter-burning type heat pipe boiler, by body of heater (20), flue (17), main smoke pipe (2), heat pipe (19), water-cooled is (15) at interval, and water pipe furnace grate (13) and fire grate (8) are formed, and it is characterized in that constituting precombustion chamber " B " between inherent water-cooled interval of described flue (17) (15) and the water pipe furnace grate (13); Constitute combustion chamber " C " between water pipe furnace grate (13) and the fire grate (8); The vault of flue (17) and water-cooled constitute Heat Room " A " between (15) at interval, the center top of Heat Room and flue collector (2) lead to, the interior annular of Heat Room " A " is provided with 6-12 root heat pipe (19), the top of heat pipe is stretched in body of heater (20) chamber, around flue (17), be provided with the fire tube (6) of annular spread, lead to the suitable for reading and combustion chamber " A " of fire tube (6), " C " leads to for its end opening and combustion chamber, the red-hot air-flow of burning can " C " enter Heat Room " A " through fire tube (6) from the combustion chamber, discharges from main smoke pipe (2) again.
The utility model has the advantages that: adopt double grate counter-burning type combustion method, fuel obtains sufficient second-time burning, reduced soot emissions, the Heat Room of heat-pipe elements and the fire tube of circular row layout are housed form rational combustion gas heat transfer process, enlarged boiler heating surface, made boiler that the higher thermal efficiency be arranged, so can reach purpose energy-conservation and the minimizing urban air pollution, this boiler can be supplied steam and hot water, is widely used in units such as office, school, factory, hotel.
Accompanying drawing 1: the utility model structural representation,
The A-A cutaway view of accompanying drawing 2: Fig. 1.
The 1-gland steam exhauster, 2-flue collector, 3-butterfly valve, 4-safety valve, the 5-hot-water line, the 6-fire tube, the 7-water-cooled is through hole at interval, the 8-fire grate, the 9-water inlet pipe, 10-sewage draining exit, 11-shoot door, 12-lower furnace door, the 13-water pipe furnace grate, 14-upper furnace door, 15-water-cooled interval, 16-inspection socket, the 17-flue, 18-water level meter, 19-heat pipe, 20-body of heater, the 21-steam gauge, " A "-Heat Room, " B "-precombustion chamber, " C "-combustion chamber.
Embodiment:
Between body of heater (20) and the flue (17) is the water storage furnace chamber, water-cooled (15) is at interval arranged in the flue (17), water-cooled grate (13), fire grate (8), the vault of flue (17) and water-cooled are formed Heat Room " A " between (15) at interval, 10 heat pipes of annular arrangement (19) bottom is in Heat Room " A ", and top is in body of heater (20) chamber.Between water-cooled interval (15) and the water-cooled grate (13) is preheating chamber " B ", constitutes combustion chamber " C " between water pipe furnace grate (13) and the main fire grate (8); 7 fire tubes (6) circular row is around flue (17), and the end opening of fire tube (6) leads to combustion chamber " C ", the Heat Room " A " that leads to suitable for reading.Flue collector (2) is led at flue (17) top.Water-cooled (15) periphery at interval has four water-cooleds through hole (7) at interval, so that water flows, known technology is provided with upper and lower fire door (14), (12), shoot door (11), blast pipe (1), hot-water line (5), water inlet pipe (9), sewage draining exit (10), safety valve (4), steam gauge (21), butterfly valve (3), inspection socket (16) and water level meter (18) routinely.
Inject soft water from water inlet pipe (9) during use, make in body of heater (20) chamber, water-cooled is (15) and the interior water-filling of water pipe furnace grate (13) at interval, sets mark R to water level meter (18); With fire-lighter and fuel respectively from upper furnace door (14), lower furnace door (12) adds on water-cooled grate (13) and the fire grate (18), close lower furnace door (12) after lighting, suction force because of flue collector (2) thermal current, form negative pressure in the combustion chamber " C ", at this moment flame rises to Heat Room " A " through annular fire tube (6), the heating end of heating heat pipe (19), go into flue collector (2), enter atmosphere through chimney.Because of the negative pressure of combustion chamber " C " makes flame and incendivity flue gas after precombustion chamber " B " burning, the gap through water pipe furnace grate (13), further burnt in the reverse high-temperature region that enters combustion chamber " C ", and auxiliary air is replenished by shoot door (11).Normal operation is only from upper furnace door (14) coal, and the carbon granule after the pre-burning drains in the space of water-cooled grate (13) on the fire grate (8) and burns away.
