Abstract
An assorted coal and pulverized coal mixing combustion boiler body comprises a boiler body. A combustion area is arranged inside the boiler body. A pulverized coal input port for connecting a pulverized coal mixing combustion conveyer is arranged on the lateral wall of the boiler body and is communicated with the combustion area. The combustion area, the pulverized coal input port, man holes and coal hoppers are distributed reasonably. When in use, the pulverized coal mixing with air evenly enters the combustion area inside the boiler and is contacted with the assorted coal which is combusted on the combustion area so as to be combusted completely, thereby greatly increasing the temperature inside the boiler, enhancing radiation strength and improving working efficiency of the boiler body. The assorted coal and pulverized coal mixing combustion boiler body is reasonable and simple in structure, easy to maintain, suitable for popularizing and application and lower in production cost and is high efficiency energy-saving equipment.
Description
Technical field
The utility model relates to a kind of coal-burning boiler body of heater, especially a kind of system coal and coal dust mixed firinor fuel burning) boiler body of heater.
Background technology
China is not only world big coal country, also is simultaneously consumption coal big country.Coal is one of important raw material of industry, and along with industrial boom, coal resources are constantly exploited consumption, world's coal reserves descends fast, because coal is fossil energy, on exploitation is used, be very limited, how farthest to utilize coal to become the current important topic that will solve.Coal is the important source material of boiler combustion, coal-burning boiler pattern on the market is various at present, come branch that system coal combustion boiler, pulverized coal firing boiler etc. are arranged by the fire coal classification, coal seam thickness in the present system coal combustion boiler furnace is wayward, and the coal seam is thin excessively, and fuel value is not enough, the coal seam is blocked up, coal not only can not fully burn, and can pyrolysis become a large amount of carbon blacks, directly influences the utilization and the air quality of coal-fired heat in the boiler furnace; The combustion system of pulverized coal firing boiler mainly is by coal dust mixed combustion conveyer (be as the patent No. 201020127507.0 Chinese patent) coal dust to be heated to boiler from the jet spray combustion, though this boiler coal dust firing efficient is higher, but coal dust jet length and injection flow are limited, its scope of application is too small, is unsuitable for the large scale industry boiler and uses.Also do not have on the market at present a kind of can with the system coal, the clean-burning system coal of coal dust reasonable combination and coal dust mixed firinor fuel burning) boiler body of heater.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and providing a kind of can satisfy the industrial development demand with system coal, the clean-burning system coal of coal dust reasonable combination and coal dust mixed firinor fuel burning) boiler body of heater.
The utility model solves the technical scheme that its technical problem adopts: this system coal and coal dust mixed firinor fuel burning) boiler body of heater, comprise body of heater, be provided with the combustion zone in the body of heater, sidewall of the furnace body is provided with the coal dust input port that coal supply powder mixed combustion conveyer connects, and the coal dust input port communicates with the combustion zone.Like this, when burn in the combustion zone of system coal in boiler furnace, coal dust is injected into the combustion zone burning by the coal dust input port, not only can improve the temperature in the boiler furnace, and the system coal that can effectively promote to be layered on the combustion zone fully burns, improve utilization rate coal-fired in the body of heater greatly, reach energy-saving effect.
Further, body of heater one end is provided with coal feeding bucket, so conveniently adds fire coal, and sidewall of the furnace body is provided with manhole, is convenient in time safeguard boiler furnace like this, uses safelyr, and the coal dust input port is located between manhole and the coal feeding bucket on the side wall of furnace.There are two groups the coal dust input port, is located at respectively on the body of heater side walls.Be more conducive to body of heater internal combustion burning of coal utilization like this.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, simple, reasonable Arrangement by combustion zone, coal dust input port, manhole, coal bunker, the coal dust mixing air is evenly entered in the stove internal combustion district, contact with aflame system coal on the combustion zone, it is fully burnt, improve temperature in the stove greatly, enhanced rad intensity has improved the operating efficiency of body of heater.The utility model is an energy-saving equipment efficiently, and is not only easy to maintenance, and production cost is also lower, is fit to apply.

Fig. 3 is the structural representation of the utility model left side apparent time.
Description of reference numerals: body of heater 1, coal dust input port 2, coal feeding bucket 3, manhole 4, combustion zone 5.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: this system coal in the present embodiment and coal dust mixed firinor fuel burning) boiler body of heater, comprise body of heater 1, be provided with combustion zone 5 in the body of heater 1, body of heater 1 one ends are provided with coal feeding bucket 3, body of heater 1 sidewall is provided with manhole 4, and the sidewall of body of heater 1 is provided with the coal dust input port 2 that coal supply powder mixed combustion conveyer is connected between manhole 4 and the coal feeding bucket 3, and coal dust input port 2 communicates with combustion zone 5, there are two groups coal dust input port 2, is located at respectively on body of heater 1 side walls.
During use, combustion zone 5 burnings of system coal in body of heater 1, coal dust is injected into combustion zone 5 burnings by the jet of coal dust mixed combustion conveyer with coal dust from coal dust input port 2, and contact with aflame system coal on the combustion zone 5, it is fully burnt, effectively avoided the generation of carbon black, improve temperature in the stove, enhanced rad intensity has improved efficiency of combustion and heat energy utilization rate in the body of heater 1, reaches effect in energy saving and environmental protection.The utility model cooperation boiler uses the back to compare with the plain cylindrical furnace burning and economizes on coal about 25%～30%.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
