Abstract
The invention discloses a kind of anti-coking boiler, key is：Including furnace body and feeding fan, the feeding fan is connected by flange with furnace body fixation, it is burner hearth in the middle part of the furnace body, the burner hearth is arranged right below slag trapping chamber, the front of the slag trapping chamber is provided with firehole before slag notch and at least 2 groups, fire door is equipped at the slag notch, the back side of the slag trapping chamber is equipped at least 2 groups of back of the body fireholes, and preceding firehole described in every group and back of the body firehole are correspondingly provided with gear aperture apparatus.A kind of anti-coking boiler of the present invention, biomass fuel powder Droplets is sent into boiler furnace by feeding fan and carries out suspension combustion, in boiler furnace, air can be brought in feeding fan into, firehole also can be that boiler supplies oxygen simultaneously, prevent the generation for the coking phenomenon for resting on high-temperature region for a long time, while the adjusting fire box temperature that air blower can also be frequently, without it is long when operate.
Description
Technical field
The invention belongs to biomass combustion boiler technical fields, specifically, are related to a kind of anti-coking boiler.
Background technology
The mode of existing biomass feeding mainly biomass fuel is deposited in around boiler, during use by
The skilled worker of operation is manually sent into fuel in boiler.And the burner hearth of boiler is substantially in closed state, in order to protect
It demonstrate,proves that oxygen supply in burner hearth is sufficient, and majority needs to add air blower to boiler, needs being carried out by air blower to boiler furnace frequently
Oxygen supply, but the temperature of burner hearth can be reduced while oxygen supply again, adjust temperature and the oxygen supply of burner hearth simultaneously by an air blower
Amount increases the difficulty of burner hearth bore temperature control, influences the quality of biomass combustion；And the lime-ash that biomass combustion generates stops
On fire grate or from the gap discharge on fire grate, worker collects them out of boiler stacking within a certain period of time, due to biology
The reason of matter fuel is peculiar.Make to contain a large amount of sodium dioxide, titanium dioxide potassium, magnesium dioxide in the lime-ash generated after burning,
Their fusion temperature is between 550 DEG C -1100 DEG C, if the lime-ash extended stationary periods generated after biomass fuel combustion are in this way
Temperature environment in, coking phenomenon will be generated；And air blower continuous service, it is fragile, considerably increase production cost.
Invention content
For solution more than technical problem, the purpose of the present invention is to provide a kind of anti-coking boilers of the present invention, can effectively control
Oxygen supply and temperature in burner hearth processed, the lime-ash that quick cleaning generates reduce production cost.
What the object of the invention was realized in：A kind of anti-coking boiler, key are：Including furnace body and feeding fan,
The feeding fan is connected by flange with furnace body fixation, is burner hearth in the middle part of the furnace body, which is arranged right below collecting
Grit chamber, the front of the slag trapping chamber are provided with firehole before slag notch and at least 2 groups, fire door, the slag trapping chamber are equipped at the slag notch
The back side be equipped at least 2 groups of back of the body fireholes, preceding firehole described in every group and the back of the body firehole be correspondingly provided with gear aperture apparatus.
Preceding firehole described in every group and back of the body firehole include at least three eyelet, and the eyelet is transversely arranged.
Above-mentioned gear aperture apparatus includes lateral slide and sliding rail, and two tracks of the sliding rail are located at every group of forehearth respectively
Hole or the upper side and lower side for carrying on the back firehole, the transverse direction slide are slidably arranged in the sliding rail.
The fixing end of above-mentioned fire door and the edge of the slag notch are hinged, and the lateral surface close to the fire door free end is equipped with door
Handle.
Lateral surface close to the fire door free end is equipped with support column, and one end of the support column is hinged with the fire door, should
The other end support ground of support column.
Above-mentioned furnace body is connected with air blower.
Advantageous effect：
A kind of anti-coking boiler of the present invention, biomass fuel powder Droplets are sent into boiler furnace by feeding fan and suspended
Burning in boiler furnace, can bring air into feeding fan, while firehole also can be that boiler supplies oxygen, make fuel 750 DEG C-
It burns at a temperature of 850 DEG C, is conducive to the moisture content volatilization inside fuel, is allowed to conflagration；And fixed carbon and lime-ash introduce
The heat exchange zone at boiler rear portion, and the temperature of this part at 600 DEG C hereinafter, the sodium dioxide of the lime-ash just prevented, titanium dioxide potassium
With the generations such as magnesium dioxide, while also prevent resting on the generation of the coking phenomenon of high-temperature region for a long time, while air blower is also
Adjusting fire box temperature that can be frequently, without it is long when operate.
