Description

The energy-conserving and environment-protective water-tube boiler of complete reverse burning

Technical field

The utility model belongs to the improvement of the civil boiler that uses solid fuel, particularly the energy-conserving and environment-protective water-tube boiler of complete reverse burning.

Background technology

Traditional water-tube boiler, its combustion chamber is positioned at the below of water pipe, adds solid fuel on fire grate, and pyrotechnics is to up after the fuel combustion, and the water in the water pipe of top, heating flame chamber is for heating and domestic water.Its weak point is that solid fuel ignition is abundant inadequately; particularly be positioned at the fuel bed that do not begin of burnt fuel layer upper strata heap; it produces at underfired fuel and produces a large amount of coal gas under the heating of scorching hot flame; the a large amount of coal gas and the combustible granules of clamping also have little time abundant burning; just the pyrotechnics that is risen is taken away, along with flue gas drains in the atmosphere through chimney.The fuel that consumes is many, and the thermal efficiency is low.

Summary of the invention

The purpose of this utility model is to provide a kind of energy-conserving and environment-protective water-tube boiler of complete reverse burning, changed the burning heating arrangement of traditional solid fuel water-tube boiler, the solid fuel in the combustion chamber is fully burnt, smoke medicining dust-removing effect is good, save solid fuel, thermal efficiency height.

The utility model is achieved in that a kind of energy-conserving and environment-protective water-tube boiler of complete reverse burning, comprise the body of heater that constitutes by the water jacket furnace wall, the combustion chamber and the heating pipe that have fire grate are being set in body of heater, uniform below fire grate the heating pipe is being set, heating pipe's two ends are communicated with the water jacket furnace wall respectively, the body of heater inner chamber that will have the heating pipe by uniform upright dividing plate is divided into, turn back the down flue of serial, wherein first order dividing plate links to each other with the combustion chamber rear wall, exhaust opening is left in its underpart, the exhaust opening of afterbody dividing plate is communicated with chimney, on the body of heater chimney air-introduced machine is installed.

When the utility model is worked, start air-introduced machine earlier, light the solid fuel on the fire grate, owing to the below generation negative pressure of fire grate in the body of heater, the flame of the solid fuel ignition of being lighted on the fire grate is to the operation of the below of fire grate, and is mobile along the flue of the upper and lower serial of turning back.Burnt fuel is burnt from bottom to top on the fire grate, a large amount of coal gas that the fuel on its upper strata produces and burnable granule are essential by the scorching hot burning zone of lower-layer fuel, fully burn, the scorching hot pyrotechnics of full combustion of fuel is along the flue operation of the upper and lower serial of turning back, fully the water among the heating pipe in the upper and lower flue of turning back of heating supplies heating and domestic water.The utility model has changed the burning heating arrangement of traditional solid fuel water-tube boiler, realizes complete reverse burning, and the solid fuel in the combustion chamber is fully burnt, and smoke medicining dust-removing effect is good, saves solid fuel, thermal efficiency height.

The utility model is described in further detail below in conjunction with accompanying drawing.
