Abstract

The utility model relates to an upward and reverse combusting apparatus for coal or coal associated with gas. A furnace chamber is divided into more than two combustion chambers form the furnace bottom by an isolated layer. Each combustion chamber is provided with a fire grate, an ash pit, a clean-out door and a primary air inlet. The heat capacity of the utility model can be designed according to the requirement, and each combustion chamber can alternate to change the coal. The coal does not need to be ignited when the coal is changed, and the ignition is rapid. The fire behavior among the combustion chambers can mutually replenish in combusting, and the flame can keep continuous vigorous in the combustion process. The fire behavior of each combustion chamber can be respectively controlled by regulating the air input of the primary air inlet of each combustion chamber. The fire is pressed when the air is stopped, and the fire is ignited when the air is fed. The fire pressing time can reach four to five days.

Description

Upper-burning is anti-to be burnt and the anti-coal-fired combustion equipment that burns semi-coal gas of upper-burning

The utility model relates to anti-burning of a kind of upper-burning and the anti-coal-fired combustion equipment that burns semi-coal gas of upper-burning.

The existing upper-burning that uses is anti-to be burnt and the anti-coal-fired combustion equipment (as anti-stove, the simple and easy gas burner of upper-burning of burning of pumping board top coal) that burns semi-coal gas of upper-burning, burning of coal is top-down carrying out from the top of coal, the volatile matter that coal combustion is separated out is all by red-hot oxide layer, it is to finish under static relatively state that burning does not have tangible zone of reduction, whole process.Therefore the chemical combustion and the mechanical ratio of combustion of coal are more complete, smoke-colour-less, the cleaner that use must be unspecial.But the thermal capacity of this kind equipment can not design too big, when the area of burner hearth and fire grate design is big, easily causing the part, coal seam to grill thoroughly ahead of time leaks out, the normal combustion in other coal seams around having a strong impact on, in combustion process, there is obvious periodic, uses the easy coking of low-melting coal in addition and can't remove.So can only manufacture and design the combustion apparatus of low capacity at present.

The purpose of this utility model provide a kind of can manufacture and design as required big thermal capacity, and can effectively overcome the periodicity that exists in the burning, keep the good combustion that original equipment has and anti-the burning and the anti-coal-fired combustion equipment that burns semi-coal gas of upper-burning of upper-burning of environmental protection characteristic simultaneously again.

The purpose of this utility model realizes in the following way: available more than one interlayer is separated to form plural at least combustion chamber with burner hearth from furnace bottom in burner hearth, the height of interlayer accounts for 1/2～2/3 of furnace height, be equipped with fire grate separately in each combustion chamber, ashcan, ashpit and an air inlet, the number of combustion chambers that is separated to form with interlayer in burner hearth is by the thermic load decision of this combustion apparatus, the area of combustion chamber generally designs below one square metre, with changing the coal cycle between the height control combustion chamber of burner hearth internal portioning layer, can control the intensity of a fire of this combustion chamber by the intake that is adjusted in a set air inlet of each combustion chamber.

Because the utility model can be provided with plural at least combustion chamber in same burner hearth, therefore its thermal capacity can design as required, and each combustion chamber can both be changed coal in turn, coal when a combustion chamber is in the burning most productive period, its combustion chamber adjacent is just in time changed coal, utilize the heat radiation of adjacent combustion chamber coal to ignite mutually when changing coal, so change coal and must not ignite again, and it is on fire fast, the intensity of a fire between each combustion chamber can be replenished when burning mutually, thereby guarantee that burned flame keeps continuing vigorous and anti-normally carrying out of burning in whole combustion process, make fired coal combustion complete.Because of the burner hearth of this combustion apparatus can be separated to form a plurality of combustion chambers, so can control the intensity of a fire of each combustion chamber respectively by regulating the intake of an air intake of combustion chamber separately, and accomplish that blowing-out is that banking fire, air-supply are just on fire, and the time of banking fire can reach four～five days.This combustion apparatus is simple in structure, be convenient to control and operation, and stoker's labour intensity is not high, and smoke medicining dust-removing effect is good, and the various coals of incendivity can be used for design and replace and transform existing most coal-fired combustion equipment.

Below in conjunction with drawings and Examples the utility model is further described:
