Abstract
The utility model relates to an anti-combustion heat pipe hot water boiler, which is a vertical heat pipe hot water boiler with the coal as the fuel. The utility model comprises an inner combustion chamber (1) and an outer combustion chamber (2); wherein, the coal combusted inside the inner combustion chamber (1) goes through the carbon layer with red fire, and then enters the outer combustion chamber (2) and is divided into a left part and a right part, and goes through a heat resistance metal screen (14), which leads to the complete combustion of the fuel; a two-layer heat pipe, i.e., a heat pipe (9) and a heat pipe (10), heat-conduction structure is arranged so that the heat generated by the combustion of the fuel can completely pass to the water inside a boiler water chamber (8). After taking the measures of the two combustion chambers and the two layers of the heat pipes, the heat efficiency of the boiler can be increased up to 80 percent, and the discharging of the fuel gas is improved. When the round coal with a sulfur-fixing agent is used as the fuel, the smoke discharging standard can meet the requirement of the Grade I environmental protection area.
Description
Technical field the utility model relates to the anti-heat pipe hot water boiler that burns of a kind of double grate.
Technical background
Existing vertical heat pipe hot water boiler, fuel is generally selected bituminous coal for use, and the dust concentration of its discharging, blackness of exhaustion and sulfur dioxide concentration do not reach the environmental requirement of country to a class environmental protection area, and the thermal efficiency also remains further to be improved.
Summary of the invention
The purpose of this utility model provides that a kind of double grate is anti-to burn vertical heat pipe hot water boiler, and when using the ball coal that is added with sulphur-fixing agent during as fuel, fume emission can reach the environmental requirement in a national class environmental protection area, and the thermal efficiency is brought up to more than 80%.
The utility model is achieved in that by the water pipe that tilts slightly with horizontal plane and surrounds inner combustion chamber, is the external combustion chamber in the inner combustion chamber outside; At many heat pipes of the vertical welding of external combustion chamber upper wall; At many heat pipes of the vertical welding of following smoke-box upper wall; The external combustion chamber is connected by lower smoke tube with following smoke-box; Following smoke-box is connected with the upper smoke tube even spaced apart of last smoke-box by the same circumference of a plurality of one-tenth, and the cylindrical shape grid that a plurality of upper smoke tubes constitute are trapped among the radiating end of all heat pipes that are welded on down the smoke-box upper wall middle; On last smoke-box, be mounted with impact tube.Fuel is dropped in the inner combustion chamber, and burned flame enters the external combustion chamber through water pipe furnace grate downwards to be separated to both sides, rises on the net through the heating resisting metal that hangs.In inner combustion chamber, a part of heat of stove fire imports in the water through water wall; Indoor in external combustion, a part of heat of stove fire imports in the interior water of hydroecium through the heat pipe of external combustion locular wall and external combustion chamber's upper wall; On the indoor top of external combustion, stove fire has been lowered the temperature and has been become flue gas and assemble to the center, upwards enter in the lower smoke tube, in lower smoke tube, a part of heat of flue gas imports in the interior water of hydroecium through the lower smoke tube wall, flue gas rises from lower smoke tube and enters play smoke-box, and a part of heat of flue gas is imported in the water in the hydroecium by heat pipe that is welded on down the smoke-box upper wall and following smoke-box wall; Top in following smoke-box, flue gas radially outward circle disperses, and rises to enter in same circumference a plurality of upper smoke tubes evenly spaced apart, and in upper smoke tube, a part of heat of flue gas is in the upper smoke tube wall imports water in the hydroecium into; Flue gas in the upper smoke tube rises and enters smoke-box, and in last smoke-box, a part of heat of flue gas is imported in the water in the hydroecium by last smoke-box wall; Top in last smoke-box, flue gas is assembled to the center, upwards enters impact tube and discharges.
By above burning and heat transfer measure, the blackness of fume emission, dustiness and sulfur dioxide concentration all improve.The thermal efficiency can be brought up to more than 80%.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Description of drawings
Accompanying drawing is the profile of a kind of specification in the utility model inverse burning hot pipe hot-water boiler series.
The specific embodiment
The described inverse burning hot pipe hot-water boiler of accompanying drawing, be constructed as follows: 1 by water pipe (11) surround in burning-out (1), 1 outer burning-out (2), 1 lower smoke tube (3), 1 following smoke-box (4), 16 become evenly upper smoke tube (5) spaced apart of same circumference, go up smoke-box (6) for 1,1 impact tube (7), 1 hydroecium (8) that holds to be heated water, (2) upper wall vertical welding is connected to 40 heat pipes (9) in the external combustion chamber, vertically weld 33 heat pipes (10) at following smoke-box (4) upper wall, in the middle of the same circumference formed cylindrical shape grid of 16 upper smoke tubes (5) evenly spaced apart are trapped among the radiating end of all heat pipes (10), the two side of inner combustion chamber (1) and upper wall water pipe (11) are welded by steel plate (12), there is refractory cement layer (13) inner combustion chamber (4) all sidewalls the inside, and inner combustion chamber (1) lower end, two side hangs stainless steel cloth (14), fire grate (15) is arranged below the external combustion chamber.
In inner combustion chamber (1), a part of heat of stove fire is in water pipe (11) wall is passed to water in the hydroecium (8).Stove fire in inner combustion chamber (1) is passed down through water pipe (11) fire grate gap, enter external combustion chamber (2), separate through stainless steel cloth (14) to rising to both sides, arrive top, external combustion chamber (2), gathering enters in the lower smoke tube (3) to the center, in external combustion chamber (2), a part of heat of stove fire is in superheater tube (9) and external combustion chamber (2) wall import water in the hydroecium (8) into.A part of heat of the flue gas in lower smoke tube (3) imports in the interior water of hydroecium (8) through lower smoke tube (3) wall.Flue gas in lower smoke tube (3) rises and enters smoke-box (4) down, and a part of heat of flue gas is in superheater tube (10) and following smoke-box (4) wall are passed to water in the hydroecium (8) in smoke-box (4) down.On the top of following smoke-box (4), flue gas radially outward circle disperses, and enters in same circumference 16 upper smoke tubes (5) evenly spaced apart, and in upper smoke tube (5), the heat of some flue gas imports in the interior water of hydroecium (8) through upper smoke tube (5) wall again.Flue gas rises from upper smoke tube (5) and enters smoke-box (6), and a part of heat of the flue gas in last smoke-box (6) passes through last smoke-box (6) wall and imports in the water in the hydroecium (8).Top in last smoke-box (6), flue gas are assembled rising to the center and are entered impact tube (7) discharge.Like this, stove fire in inner combustion chamber (1) is downwards by red fire carbon layer and fully burning of stainless steel cloth (14), again through repeatedly tortuous by way of and the heat transfer of two heat pipe layers, heat exchange and depositing dust effect have been carried out fully, make the thermal efficiency of the utility model inverse burning hot pipe hot-water boiler reach more than 80%, when using ball coal with sulphur-fixing agent as fuel, blackness of exhaustion, dust concentration and sulfur dioxide emissioning concentration all can reach the emission request of country to a class environmental protection area.
