Abstract

The coal-fired furnace of the utility model comprises a preheat chamber of coal storage, blades, an air channel, an air pipe, a speed control device, a blower fan and a coal-charging bucket. The blades of run coal are provided and the air channel and the air pipe are additionally provided to blow upward with brute force, so a high-temperature region is formed by burning on the upper part of the preheat chamber of coal storage, which can avoid high temperature to burn out the coal-fired furnace. When the raw coal is raised in a coal storage chamber, crude gas and other harmful substances produced after the raw coal encounters the burning layer on the upper part to be preheated are burnt off by burning flames in the burning chamber, such as sulfide is burnt off by high temperature flames and is solidified. Thus, all the discharges can obtain the standard of state environmental protection, and combustion is sufficient, which can economize a large quantity of coal; the carbon monoxide is approximate zero; the high temperature can be created rapidly; adopting the design of no fire grate, the utility model is easy to operate and use; the coal-fired furnace can be used for boilers, kilns, chemical industries, brewing wine, etc. The fired coal can obtain the standard of the state environmental protection; in addition, banking fire can obtain more than 30 hours; operation is also convenient.

Description

Coal furnace

Affiliated technical field:

The utility model belongs to coal combustion equipment, particularly be a kind of no fire grate coal furnace.

Background technology:

Make the energy with coal, civilianly heat up water, cook, bathing, heating and industrial coal be that China is like this always since ancient times, urgent along with environmental requirement, it is also more and more tighter to improve combustion apparatus, retrieves existing relevant patent and existing stove and accessory, though the performance performance is good, but in practicality, do not reach the index in the file, and exist the preheating chamber passage to make coal-fired high-temperature region more, burn obviously in the preheating chamber bottom, change part, maintenance frequently, bring inconvenience.

Summary of the invention:

The purpose of this utility model provides a kind of sufficient combustion, makes fire coal reach national environmental standard, and can raise the furnace high-temperature district, and the no fire grate that stove was obviously improved with the life-span seals the environmental protection coal furnace of coal storage preheating chamber.

The purpose of this utility model be achieved in that specify as follows:

Coal furnace is made up of coal storage preheating chamber, blower fan, the bucket of coalingging, its design feature is: the coal storage preheating chamber is closed, establish loose coal fan page or leaf in the coal storage preheating chamber, be positioned at and connect as one with loose coal flabellum after the speed control device axle of side passes coal storage preheating chamber bottom under the coal storage preheating chamber; Between the coal storage preheating chamber upper wall outside and blower fan actinal surface plate, establish annular passage, on place, air channel coal storage preheating chamber upper wall, all establish at least 3 airducts and point in the coal storage preheating chamber internal upper part chamber.

Advantage of the present utility model is clearly: this coal furnace blows because of establishing on the loose coal fan page or leaf brute force, with set up air channel and airduct, so be that burning forms the high-temperature region on coal storage preheating chamber top, again because of adding the coal supply of bottom, air channel, when soft coal rises in coal storeroom, the flame that runs into the harmful substances such as crude gas that produce after the burning zone preheating of top and be burned Indoor Combustion is burnt, and is burnt by thermal-flame and solidifies as sulfide; So discharging all can obtain national environmental standard, contain 30% heat because of coal smoke simultaneously, fully the heat that produces after the burning can be saved coal in a large number; Because of being mandatory burning, can improve the coal burning rate, carbon monoxide emission is approximately zero; And can produce high temperature fast, raising is exerted oneself; This coal furnace adopts no fire grate, and no dreg removing system design can avoid cinder, stone etc. to stop up fire grate, and is easy for operation; The coal storage preheating chamber adopts closed design, can avoid high temperature to burn out this coal furnace; Coal furnace can be used for boiler, kiln, chemical industry, wine brewing, etc. the burned mechanism in burning top, bottom.Make fire coal reach national environmental standard, and save coal and improve coal consumption rate, raising is exerted oneself; In addition, banking up a fire to reach more than 30 hour, and operation is also convenient.

Description of drawings:

Fig. 1 is the utility model cross-sectional view

Fig. 2 is the utility model schematic top plan view

Among the figure, the 1st, coal storage preheating chamber, the 2nd, fan page or leaf, the 3rd, air channel, the 4th, airduct, the 5th, speed control device, the 6th, blower fan, the 7th, the bucket of coalingging, the 8th, coal outlet, the 9th, furnace shell.

Be positioned at and connect as one with loose coal flabellum 2 after coal storage preheating chamber 1 beneath 5 square of speed control devices pass coal storage preheating chamber bottom; Establish annular swash plate and former coal storage preheating chamber 1 corresponding top wallboard in blower fan 6 exits and form the air channel 3 of a circle ring sector sealing, and in the top wall of former coal storage preheating chamber 1 correspondence, establish at least 3 equably, general 3-9 airduct 4 that points to the ring heart, the wind that blower fan 6 is blown out is introduced into air channel 3 and is directly blowing the coal center through airduct 4, guarantees that oxygenation is combustion-supporting.

The specific embodiment:

Operating feature: earlier coal is adopted conventional multiple mode, as spiral, jacking type, oscillatory type etc., make the coal that looses enter closed coal storage preheating chamber 1 in the stove through coaling bucket 7 and coal outlet 8, in coal storage preheating chamber 1 bottom the fan page or leaf 2 that loose coal is used is installed, drive fan page or leaf 2 with speed control devices such as frequency modulation type motor or reductor 5, make fan page or leaf 2 by slowly gradually rotating soon, make the coal in the coal storage preheating chamber 1 rise to the combustion chamber, after lighting, start blower fan 6,3 evenly send wind into the combustion chamber through the air channel, force coal burning, form the top burning of fire in coal storage preheating chamber 1, coal is constantly from bottom to top supplied with as required, heats the lime-ash behind the burned fire coal, discharge through slag notch, can bank up a fire after closing blower fan 6, banking up a fire can reach more than 30 hours, the fire of can annual use need not living again; Body of heater 9 is support bodies of whole stove.

The utility model is exactly to be the vertical boiler of 0.15-1T/h with evaporimeter, removes fire grate with the lower part, and pot body directly seat is combined into a kind of New-type boiler on this combustion furnace.

The utility model technical staff of the same trade all can implement.
