Abstract
The invention discloses an anti-coking boiler. The anti-coking boiler is characterized by comprising a boiler body and a feed fan; the feed fan is fixedly communicated with the boiler body through a flange; a hearth is formed in the middle part of the boiler body; a slag collecting chamber is formed rightly below the hearth; a slag outlet and at least two sets of front boiler holes are formed in the frontal surface of the slag collecting chamber; a boiler door is formed in the slag outlet; at least two sets of back boiler holes are formed in the back surface of the slag collecting chamber; and each set of front boiler holes and each set of back boiler holes are correspondingly provided with hole shielding devices. According to the anti-coking boiler, biomass fuel powder is fed into the hearth of the boiler through the feed fan for suspension burning; in the hearth of the boiler, air is taken into the feed fan, and at the same time, oxygen can be supplied to the boiler through the boiler holes to prevent the generation of coking phenomenon caused by long-time stop in a high-temperature area; and meanwhile, an air blower can occasionally adjust the temperature of the hearth, so that long-time operation is not needed.
Description
Technical field
The invention belongs to biomass combustion boiler technical field, specifically, relate to a kind of anti-coking boiler.
Background technology
The mode of existing living beings feeding is mainly deposited in biomass fuel around boiler, use process in by the skilled worker operated with manually fuel being sent in boiler.And the burner hearth of boiler is substantially all be in closed state, in order to ensure that in burner hearth, oxygen supply is sufficient, majority needs to add air blast to boiler, need frequently by air blast, oxygen supply is carried out to boiler furnace, but the temperature of burner hearth can be reduced again while oxygen supply, regulated temperature and the oxygen-supplying amount of burner hearth by an air blast simultaneously, increase the difficulty that burner hearth bore temperature controls, affect the quality of biomass combustion; And the lime-ash that biomass combustion produces rests on fire grate or from the space discharge fire grate, workman collects stacking them within a certain period of time in boiler, due to the distinctive reason of biomass fuel.Burning is produced afterwards lime-ash in containing a large amount of sodium dioxide, titanium dioxide potassium, magnesium dioxide, their fusion temperature is between 550 DEG C-1100 DEG C, if the lime-ash extended stationary periods produced after biomass fuel combustion is in such temperature environment, coking phenomenon will be produced; And air blast continuous service, fragile, considerably increase production cost.
Summary of the invention
For solving above technical problem, the object of the present invention is to provide a kind of anti-coking boiler of the present invention, effectively can control the oxygen supply in burner hearth and temperature, the lime-ash that cleaning produces fast reduces production cost.
The present invention seeks to realize like this: a kind of anti-coking boiler, its key is: comprise body of heater and feeding fan, described feeding fan is fixedly communicated with described body of heater by flange, it is burner hearth in the middle part of this body of heater, be provided with slag trapping chamber immediately below this burner hearth, the front of this slag trapping chamber has firehole before slag notch and at least 2 groups, and described slag notch place is provided with fire door, the back side of described slag trapping chamber is provided with at least 2 group back of the body fireholes, often organizes described front firehole and carry on the back the equal correspondence of firehole to be provided with gear aperture apparatus.
Often organize described front firehole and carry on the back firehole and include at least 3 eyelets, described eyelet is transversely arranged.
Above-mentioned gear aperture apparatus comprises horizontal slide and slide rail, and two tracks of described slide rail lay respectively at the upper side and lower side of the front firehole of described often group or back of the body firehole, and described horizontal slide is slidably arranged in described slide rail.
The stiff end of above-mentioned fire door and the edge of described slag notch hinged, be provided with door handle near the lateral surface of this fire door free end.
Lateral surface near described fire door free end is provided with support column, and one end and the described fire door of this support column are hinged, and the other end of this support column supports ground.
Above-mentioned body of heater is connected with air blast.
Beneficial effect:
A kind of anti-coking boiler of the present invention, living beings fuel powder Droplets is sent in boiler furnace by feeding fan and carries out suspension combustion, in boiler furnace, air can be brought in feeding fan, firehole also can be boiler oxygen supply simultaneously, fuel is burnt at the temperature of 750 DEG C-850 DEG C, is conducive to the moisture content volatilization of fuel inside, makes it conflagration; And fixed carbon and lime-ash introduce the heat exchange zone at boiler rear portion, and the temperature of this part is below 600 DEG C, the sodium dioxide of the lime-ash just prevented, the generation such as titanium dioxide potassium and magnesium dioxide, also prevent the generation of the coking phenomenon resting on high-temperature region for a long time simultaneously, simultaneously air blast can also regulating stove bore temperature frequently, without the need to operating time long.
