Abstract
The utility model provides a coal fired boiler which comprises a boiler body, an air inlet and a chimney. The chimney is arranged at the top end of the boiler body; a slag receiving device is arranged at the bottom end inside the boiler body; the slag receiving device is of a double-layer drawer structure; a filter screen is arranged at the bottom of the upper part of the slag receiving device; a fire grate is arranged above the slag receiving device; the fire grate is of a wave shape; vent holes are respectively distributed at the wave crest and wave trough positions of the fire grate; the air inlet is formed on the side wall of the boiler body between the slag receiving device and the fire grate; a desulfuration and dust removal device are arranged at an outlet of the chimney; and the top of the desulfuration and dust removal device is provided with an exhaust port. The coal fired boiler has the beneficial effects that the slag receiving device is of a double-layer drawer structure and the filter screen is arranged inside the slag receiving device, so that separation of slags and ash can be implemented and the slags and the ash are respectively processed; and the waveform fire grate enables fuel coal and the air to be more sufficiently in contact and enables burning to be carried out more completely.
Description
Technical field
The utility model belongs to field of boilers, especially relates to a kind of coal-burning boiler.
Background technology
Coal-burning boiler is to using fire coal as the boiler of fuel, and it still uses in a large number in vast rural area.The slag of existing coal-burning boiler and ashes mix the bottom that is deposited on boiler conventionally, deal with very inconvenient, and; fire grate is flat mostly, more when the Coal-fired capacity adding, and piles up when tight; cause sluggish in air circulationly, make fired coal combustion insufficient, cause energy waste.
Utility model content
The purpose of this utility model is to provide a kind of coal-burning boiler simple in structure, easy to use.
The technical solution of the utility model is: a kind of coal-burning boiler, comprise body of heater, air inlet and chimney, the top of described body of heater is provided with chimney, the bottom of described body of heater inside is provided with slag receiving system, described slag receiving system is double-drawer formula, bottom, upper strata is provided with filter screen, the top of described slag receiving system is provided with fire grate, described fire grate undulate, crest and wave trough position place are placed with respectively air vent, on sidewall of the furnace body between described slag receiving system and fire grate, be provided with air inlet, the exit of described chimney is provided with desulfation dust-extraction device, the top of described desulfation dust-extraction device is provided with exhaust outlet.
Further, on the upper and lower outer wall of described slag receiving system, be respectively arranged with a handle.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, slag receiving system is double-drawer formula, inside is provided with filter screen, can realize the separated of slag and ashes, respectively it is processed, corrugated fire grate makes fire coal contact more fully with air, burns more complete.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1-2, a kind of coal-burning boiler of the utility model, comprise body of heater 1, air inlet 2 and chimney 3, the top of described body of heater 1 is provided with chimney 3, the bottom of described body of heater 1 inside is provided with slag receiving system 4, described slag receiving system 4 is double-drawer formula, bottom, upper strata is provided with filter screen 5, the top of described slag receiving system 4 is provided with fire grate 6, described fire grate 6 undulates, crest and wave trough position place are placed with respectively air vent 7, on body of heater 1 sidewall between described slag receiving system 4 and fire grate 6, be provided with air inlet 2, the exit of described chimney 3 is provided with desulfation dust-extraction device 8, the top of described desulfation dust-extraction device 8 is provided with exhaust outlet 9, on the upper and lower outer wall of described slag receiving system 4, be respectively arranged with a handle 10, the upper and lower can be pulled out respectively.
The course of work of this example: after the fired coal combustion in body of heater on fire grate, the slag producing and ashes enter slag receiving system 4 by the air vent 7 of fire grate 6, slag drops on the filter screen 5 on upper strata, ashes see through filter screen 5 and enter lower floor, realize the effective separated of slag and ashes, pull out respectively the upper and lower, can process slag and ashes, convenient, the flue gas producing after fired coal combustion enters desulfation dust-extraction device 9 from chimney 3 is discharged, after desulfurization and dedusting is processed, from exhaust outlet 10, discharge, reduced the pollution to environment.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
