Abstract
The utility model relates to a time-sharing and layering coal feeding combustion boiler body of a coal-fired boiler, comprising a boiler body and a coal hopper, wherein the coal hopper is arranged at one side of the boiler body and comprises an upper coal hopper and a lower coal hopper; an upper conveyer belt and a lower conveyer belt are respectively arranged at the positions of coal outlets of the upper coal hopper and the lower coal hopper; and the coal outlet end of the upper conveyer belt is arranged right above a lower-temperature combustion zone of the lower conveyer belt. The time-sharing and layering coal feeding combustion boiler body breaks through the tradition of the single-coal-layer conveyer belt of the boiler body, realizes time-sharing and layering coal feeding combustion through the arrangement of the upper coal hopper, the lower coal hopper, the upper conveyer belt and the lower conveyer belt, effectively increases the utilization rate and combustion efficiency of coal and reduces the production cost. Moreover, the time-sharing and layering coal feeding combustion boiler body has reasonable and simple structure and long service life, is convenient to use and easy to maintain and is suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of power economized boiler body of heater, and especially a kind of coal-burning boiler is time-sharing layered to advance the coal combustion body of heater.
Background technology
Traditional coal-burning boiler has only a conveyer belt.Because the coal combustion mode mainly is from top to bottom to catch fire by the hyperthermia radiation to the surface, coal seam in the boiler, adopts traditional single conveyer belt, enter the interior coal seam of stove if too thin, though convenient burning, combustion heat value is low excessively to be difficult to satisfy the demands; Enter the interior coal seam of stove if too thick, combustion air is difficult to blow through, and coal is difficult to catch fire at low-temperature space, and the part coal is not having the combustion phases through it just directly to enter the high-temperature region, make this a part of coal fail completing combustion and just be taken as cinder and discharge out of the furnace, reduce the utilization rate of coal.Therefore be badly in need of occurring having the time-sharing layered coal-burning boiler body of heater that advances coal combustion and improve the utilization rate and the efficiency of combustion of coal.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides that a kind of coal-burning boiler is time-sharing layered to advance the coal combustion body of heater, satisfies the production demand.
The utility model solves the technical scheme that its technical problem adopts: this coal-burning boiler is time-sharing layered to advance the coal combustion body of heater, comprise body of heater, coal bunker, described coal bunker is located at body of heater one side, coal bunker comprises coal bunker, following coal bunker, describedly go up coal bunker, the coal outlet place of coal bunker is provided with upper conveyor belt, conveyer belt down respectively down, the coal exit of upper conveyor belt be located at down low-temperature burning district on the conveyer belt directly over.Like this, by being set, upper and lower coal bunker can realize that timesharing advances coal combustion; Carry out layering and deliver coal by upper and lower conveyer belt is set, make that the coal on the upper and lower conveyer belt can both be fully burned.Coal seam on the upper conveyor belt is last coal seam, coal seam on the following conveyer belt is following coal seam, following coal seam is thinner, and last coal seam is thicker, during use, following coal seam is after the low-temperature burning district on the following conveyer belt catches fire, restart upper conveyor belt and will go up orderly shop, coal seam on the following coal seam of fired state, surface, last coal seam is from top to bottom caught fire by hyperthermia radiation, is subjected to the following coal seam auxiliary combustion of fired state simultaneously again, make coal be able to abundant burning, effectively raise coal utilization rate and efficiency of combustion.
Further, last coal bunker is located at down the front upper place of coal bunker.Also make things convenient for plant maintenance when making things convenient for coal like this.Be provided with the coal breakage skew wall between upper conveyor belt and the following conveyer belt, this coal breakage skew wall coal-feeding end connects the coal exit of upper conveyor belt, the coal exit of this coal breakage skew wall be located at down conveyer belt directly over.Guarantee orderly will being layered on down on the coal seam of last coal seam energy like this, avoided conveyer belt directly to enter in the stove simultaneously and burnt out, improved the service life of body of heater greatly.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, simple, break the tradition of the single coal seam of boiler furnace conveyer belt, realize the time-sharing layered coal combustion that advances by being provided with of upper and lower coal bunker and upper and lower conveyer belt, effectively improve coal utilization rate and efficiency of combustion, reduce production costs.The utility model long service life, easy to use, safeguard simple and easyly, be fit to apply.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: body of heater 1, coal bunker 2, last coal bunker 2-1, following coal bunker 2-2, upper conveyor belt 3, following conveyer belt 4, coal breakage skew wall 5.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: this coal-burning boiler in the present embodiment is time-sharing layered to advance the coal combustion body of heater, comprise body of heater 1, coal bunker 2, described coal bunker 2 is located at body of heater 1 one sides, coal bunker 2 comprises coal bunker 2-1, following coal bunker 2-2, last coal bunker 2-1 is located at down the front upper place of coal bunker 2-2, describedly go up coal bunker 2-1, the coal outlet place of coal bunker 2-2 is provided with upper conveyor belt 3, conveyer belt 4 down respectively down, the coal exit of upper conveyor belt 3 be located at down low-temperature burning district 6 on the conveyer belt 4 directly over.Be provided with coal breakage skew wall 5 between upper conveyor belt 3 and the following conveyer belt 4, this coal breakage skew wall 5 coal-feeding ends connect the coal exit of upper conveyor belt 3, the coal exit of this coal breakage skew wall 5 be located at down conveyer belt 4 directly over.
By being set, upper and lower coal bunker can realize that timesharing advances coal combustion; Carry out layering and deliver coal by upper and lower conveyer belt is set, make that the coal on the upper and lower conveyer belt can both be fully burned, improve burning of coal efficient and utilization rate.Coal on the upper conveyor belt is last coal seam, coal on the following conveyer belt is following coal seam, during use, control is the coal input quantity of coal bunker down, make down squeeze, even following coal seam enters in the body of heater combustion air and blows through easily at low-temperature burning district coal and be easy to catch fire, last coal seam is thicker, to go up the coal seam by upper conveyor belt, coal breakage skew wall evenly is layered on the following coal seam of fired state, surface, last coal seam is from top to bottom caught fire by hyperthermia radiation, be subjected to simultaneously the following coal seam auxiliary combustion of fired state again, make coal be able to abundant burning, effectively raise coal utilization rate and efficiency of combustion.
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.
