Description
Technical field
The utility model relates to field of boilers, in particular to a kind of horizontal three return-stroke biomass fuel boilers.
Background technique
Boiler is a kind of energy conversion, and the energy inputted to boiler has chemical energy, electric energy, high-temperature flue gas in fuel
The forms such as thermal energy, and pass through boiler and convert, output has steam, high-temperature water or the organic heat carrier of certain thermal energy outward.?
It is that structure is simple mostly that China, which is especially used as coal-fired, burning firewood boiler product, low production cost, boiler tail smoke evacuation
Very high " Washdown type " boiler of temperature.Waste of fuel is very big, and the thermal efficiency is not high.Energy Efficiency Ratio is extremely unreasonable at most of vertical boilers
The common fault of furnace.
Steam boiler can be divided into electric steam boiler, oil-fired steam boiler, combustion and steam pot according to fuel (electricity, oil, gas)
Three kinds of furnace；Vertical steam boiler, horizontal steam boiler can be divided into according to construction.Horizontal steam boiler generally by boiler body,
The composition such as front smoke box, rear smoke box, burner, explosion vent apparatus, explosion proof door is a kind of safety device to protect boiler setting, when
When misoperation, it may cause burner hearth or tail in igniting or operation using coal dust, oil or fuel gas as the room-fired boiler of fuel
Detonation or second-time burning occur for portion's flue, and furnace pressure is caused to increase, and when pressure rise to certain value, anti-explosive door for boiler can be certainly
Row opens pressure release to protect boiler setting.
Explosion proof door used in water heater has explosion membrane type and two kinds of swing type, and explosion membrane type explosion proof door is by rupture disk and clamping
Device composition.Rupture disk is generally made of sheet metals such as asbestos, aluminium and stainless steels.When explosion time occurs in burner hearth or flue,
When the gas shock wave pressure of generation destroys rupture disk, play the role of pressure release, explosion membrane type explosion proof door once after, just
Will not self-resetting, and be switched on clamping device and reappose rupture disk.Rotary opening type anti-explosion door is installed on the furnace of combustion chamber more
On wall.It is divided into tilting and two kinds rectilinear by its installation site, is made of components such as doorframe, door closure and hinges.Work as burner hearth
Or when gas burst occurring in flue, door closure opens pressure release around axis automatically, then and voluntarily closes.The sealed pressure of explosion proof door
The downward pressure generated by door closure tilt angle (being usually no more than 30 °) or the weight acquisition by weight.
Currently, the mode that two kinds of explosion proof doors are the directly pressure release after detonation or second-time burning occurs carry out it is explosion-proof, it is explosion-proof
Door draw off pressure it is larger when will generate biggish sonic impinging to ambient enviroment, damage on-site producing devices, also to production operation
Personnel cause life threat, generate serious production accident.Therefore, design contains the one kind that can buffer detonation shock wave explosion proof door
Fuel boiler has realistic meaning very much for a person skilled in the art.
Utility model content
Based on problem above, the utility model provides a kind of horizontal three return-stroke biomass fuel boiler.The utility model
The shock wave progress generated is increased using level 2 buffering and to boiler furnace pressure by the way of setting vacuum chamber between level 2 buffering
Buffering is effectively reduced the shock wave that explosion proof door pressure release comes out, avoids shock wave from damaging on-site producing devices, to production operation personnel
Life threat is caused, generates serious production accident, while the high-temperature flue gas after burning passes through the round-trip heat exchange of three backhauls, greatly
The exhaust gas temperature of boiler tail and the smoke content of flue gas are reduced greatly, has effects that energy-saving and environmental protection are double, designs reasonable, thermal effect
