Abstract
The utility model relates to a coal-burning boiler, in particular to a drawer type three grids circulation multi-layer coal burning environment protection energy-saving boiler. The boiler body is designed into three burning zones. The utility model comprises a pot body, a boiler body, a smoke chamber, a fire tube, a heat exchanger. The utility model is characterized in that the boiler body is divided into three burning zones which are respectively a primary burning zone, a secondary burning zone and the release zone of residual heat from the top to the bottom; each burning zone is connected with a cooling fire grate together, which is a drawer type additional coal bed which can be pumped and be changed place upward and downward; the pot body is arranged on the upper part of the primary burning zone. The drawer type three grids circulation multi-layer coal burning environment protection energy-saving boiler adopts the burning method, and the effect of environmental protection obtains the emission standard prescribed by the state without acoustic noises. At the aspect of energy conservation, the burning method is adopted, so the burning rate of coal can obtain more than 98 percent, and the method is superior to the traditional burning method.
Description
Technical field
The utility model relates to coal-burning boiler, and referring in particular to Proper Design is the drawer type three lattice circulation multi-layered type coal combustion energy-saving environmental protection boilers of three combustion zones.
Background technology
At present the boiler of combustion coal all is combustion zone of a burner hearth, normally adds coal combustion in burner hearth, and during coal moulded coal be careless bulk storage in burner hearth, not only moulded coal takes up space greatly, the efficient of burning is not high yet, dust is bigger when slagging tap.Simultaneously, the power of boiler is difficult to improve.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of novel structure, reasonable is provided, and qualified discharge does not have noise, efficiency of combustion height, high-power drawer type three lattice circulation multi-layered type coal combustion energy-saving environmental protection boilers.
The technical scheme that realizes the utility model purpose is such: the utility model is made up of pot body, body of heater, smoke-box, fire tube, heat exchanger, its characteristics are that body of heater is divided into three combustion zones, be respectively primary zone, secondary zone, waste heat release district from top to bottom, and each combustion zone adds the coal seam with the cooling fire grate for the drawer type that can twitch and can replace up and down, and the pot body is located at top, primary zone.
The utility model is divided into three combustion zones with the burner hearth of boiler, coal in the burner hearth is fully burnt, and waste heat can make full use of, improved the thermal efficiency greatly, because coal is moulded coal to be divided into multilayer be added in the combustion zone, not only saved the combustion space, also for abundant burning and improve the thermal efficiency, the power that improves molded coal boiler provides guarantee.The utility model adopts this combustion method, and its environment protecting all reaches national specified discharge standard, and does not have noise.Aspect energy-conservation, adopt this combustion method, its burning of coal rate can reach more than 98%, is better than traditional combustion method.
Description of drawings
Accompanying drawing is the utility model structural representation
The specific embodiment
By accompanying drawing as can be known, the utility model is made up of pot body (17), body of heater (8), smoke-box (5,18), fire tube (4), heat exchanger (3), its characteristics are that body of heater (8) is divided into three combustion zones, be respectively primary zone (15), combustion district, shop (13), waste heat release district (11) from top to bottom, and each combustion zone adds the coal seam with the cooling fire grate for the drawer type that can twitch and can replace up and down, and pot body (17) is located at top, primary zone.

Operation principle of the present utility model:
1, the interior waste heat of body of heater (8) moulded coal that discharges district (11) has been after after-flame and waste heat have discharged, with firing machine with this lattice extraction.
2, will extract on these lattice the moulded coal of after-flame out and remove, again last 2 to 7 layers (quantity of every stratotype coal is determined by the size of burner hearth and the size of moulded coal) unburned moulded coal of sign indicating number as required.
3, will assist these lattice of right district (13) with firing machine and move to waste heat release district (11), these lattice of primary zone (15) will be moved to auxilliary right district (13).
4, with firing machine these lattice of new coal are put into the position of primary zone (15).
5, the coal that according to said method circulates.
6, the high-temperature flue gas of moulded coal burning generation enters first smoke chamber (5) along fire tube (4), enters second smoke chamber (18) through fire tube (4) again, is discharged by chimney (19) then.
7, high-temperature flue gas and radiations heat energy heat up the liquid in the body of heater to the bottom of a pan and fire tube heating, by heat exchanger (3) heat are taken away again.
