Technical field
The utility model is related to partial structurtes in a kind of boiler, more particularly to a kind of new coal powder boiler furnace knot
Structure.
Background technology
Boiler is a kind of energy conversion, and the energy to boiler input has chemical energy in fuel, electric energy, and boiler exports
There is steam, high-temperature water or the organic heat carrier of certain heat energy.The original meaning of pot refers to the water container of heating on fire, and stove refers to burn
The place of fuel, boiler includes pot and stove two large divisions.In boiler, the hot water producing or steam can be directly industrial production and people
Heat energy needed for people's livelihood offer alive, also can be converted to mechanical energy by Steam Power Equipment, or be turned mechanical energy by generator
It is changed to electric energy.The boiler providing hot water is referred to as hot-water boiler, is mainly used in living, and also has a small amount of application in industrial production.Produce
The boiler of steam is referred to as steam boiler, is often simply called boiler, is used for thermal power station, ship, locomotive and industrial and mining enterprises.
The burner hearth of boiler, that is, the combustion chamber of boiler it is adaptable to burning space.Burner hearth is to be surrounded by furnace wall to supply fuel
The solid space of burning.The effect of burner hearth is to ensure that fuel burns as much as possible, and it is right so that flue gas temperature of hearth outlet is cooled to
The temperature that stream heating surface trouble free service allows.For this reason, burner hearth should have enough spaces, and arrange enough heating surfaces.Additionally, should
There are rational shape and size, in order to coordinate with burner, organize Furnace Aerodynamic Field, make that flame is not adherent, do not rush wall,
Degree of filling is high, and wall thermic load is uniform.
The cross section of combustion chamber is generally square or rectangle.Fuel forms flame and high temperature cigarette in burning Indoor Combustion
Gas, so the furnace wall of combustion chamber surrounding is made up of exotic material and insulation material.Water-cooled is often laid on the inner surface of furnace wall
Wall pipe, it had both protected furnace wall will not burn out, and absorbed a large amount of radiant heat of flame and high-temperature flue gas again.The structure of combustion chamber, shape
Shape, volume and height will ensure full combustion of fuel, and so that the flue-gas temperature of combustor exit is reduced to slag and starts to condense
Temperature below.
At present, the feeding manner of pulverized-coal fired boiler has a lot, but not enough to the utilization rate of coal dust, in the burning of boiler internal
Efficiency is not highly desirable it is impossible to meet the market demand.
Utility model content
The purpose of this utility model is to provide for one kind and has convenient operation, high degree of automation, coal dust utilization ratio
High and burn fully, smoke dust produces less, a kind of new coal powder boiler combustion cell structure the advantages of convenient use.
In order to realize the purpose of this utility model, the utility model is realized by following technological means: a kind of new
Coal powder boiler combustion cell structure, including boiler furnace；It is characterized in that: described boiler furnace front is provided with charging aperture,
Boiler furnace bottom is provided with fire grate, and described boiler furnace top is provided with fume emission mouth；Connect outside described charging aperture into
Wind passage, is provided with feeding-passage above described air intake passage；Described boiler combustion chamber interior is provided with oxygenating passage.
The inside outer end of described air intake passage is provided with feeding fan, is provided with sieve positioned at feeding-passage bottom in air intake passage
Net.
Described charging aperture is in arc lower near the side of combustion chamber.
The inside outer end of described oxygenating passage is provided with oxygenating blower fan.
Described feeding-passage is in skewed to charging aperture.
Utility model works principle:
In the utility model, coal dust enters in air-supply passage by feeding-passage, and the charging blower fan in air-supply passage will
Coal dust is blown in charging aperture, and charging aperture is in downward arc due to end, makes coal dust when entering combustion chamber, is under tiltedly
Side enters combustion chamber, then in burning Indoor Combustion；And the oxygenating blower fan of combustion chamber can carry in boiler internal combustion chamber
For sufficient oxygen, so that combustion chamber coal dust is fully burnt, improve coal utilization；Flue gas after burning passes through flue gas
Floss hole is discharged；And the dust of combustion chamber can be by precipitating under fire grate phase.
The beneficial effects of the utility model:
The utility model has convenient operation, high degree of automation, and coal dust utilization ratio is high and burns fully, smoke dust
Produce less, the advantages of convenient use.
