Implement the embodiment of the utility model provides a, following beneficial effect has: the utility model discloses a coal -fired boiler leads to in the grate has the cooling water, effectively reduces stove exhaust gas temperature degree, the life of extension grate, and the waste of the energy is avoided in letting in the boiler to the cooling water that is heated simultaneously.
Description
Technical field
This utility model relates to a kind of field of boilers, particularly relates to a kind of coal-burning boiler.
Background technology
Coal-burning boiler is the boiler using fire coal as fuel, is widely used in productive life. Fire coal is deposited on fire grate and burns, and owing in combustion process, temperature is higher, fire grate is chronically in hot environment, it is easy to temperature distortion, reduces the life-span of fire grate.
Utility model content
This utility model embodiment technical problem to be solved is in that, is chronically in the middle of hot environment for present coal boiler grate, affects the situation in guideboard service life, it is proposed that a kind of coal-burning boiler.
In order to solve above-mentioned technical problem, this utility model embodiment provides a kind of coal-burning boiler, and this coal-burning boiler includes: body of heater, and body of heater is hollow structure; Boiler, boiler is arranged at above body of heater; Fire grate, fire grate is arranged in body of heater, and for hollow structure, UNICOM's outer wall to body of heater is distinguished at two ends; Water pump, water pump is connected with one end of fire grate by water inlet pipe, it is possible to supply water in fire grate; Outlet pipe, outlet pipe one end connects the other end of fire grate, with being discharged by the water in fire grate.
Wherein, the other end UNICOM of outlet pipe is to boiler.
Wherein, body of heater upper end is further provided with a chimney.
Wherein, bottom of furnace body is further provided with collection apparatus for ash.
Implementing this utility model embodiment, have the advantages that coal-burning boiler of the present utility model is connected with cooling water in fire grate, effectively reduce fire grate temperature, extend the service life of fire grate, heated cooling water passes in boiler simultaneously, it is to avoid the waste of the energy.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the coal-burning boiler that this utility model provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to the structural representation that Fig. 1, Fig. 1 are the coal-burning boilers that this utility model provides. Coal-burning boiler includes: body of heater 1, boiler 2, fire grate 3 and water pump 4.
Body of heater 1 includes chimney 11 and collection apparatus for ash 12. Body of heater 1 is a hollow structure, and body of heater 1 top is provided with a chimney 11, is provided with a collection apparatus for ash 12 bottom body of heater 1.
Boiler 2 is arranged at the top of body of heater 1.
Fire grate 3 is arranged in body of heater 1, and fire grate 3 is hollow structure, and two ends are UNICOM's water inlet pipe 31 and outlet pipe 32 respectively, and outlet pipe 32 other end UNICOM is to boiler 2.
Water pump 4 connects the other end of water inlet pipe 31, it is possible to supply water wherein.
In production process, coal is placed on fire grate 3 and burns, and water pump 4 supplies water in water inlet pipe 31, and cooling water passes sequentially through water inlet pipe 31, fire grate 3, outlet pipe 32, enters finally in the middle of boiler 2. Cooling water can effectively reduce the temperature of fire grate 3, increases the service life, and heated cooling water enters in the middle of boiler 2 simultaneously, supplement boiler 2 loss of water, does not make this portion of energy slattern.
Implementing this utility model embodiment, have the advantages that coal-burning boiler of the present utility model is connected with cooling water in fire grate, effectively reduce fire grate temperature, extend the service life of fire grate, heated cooling water passes in boiler simultaneously, it is to avoid the waste of the energy.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
