Abstract

The invention discloses an energy saver of a coal-fired boiler. The technical scheme of the invention is as follows: a hot water tank is arranged outside the coal-fired boiler, the upper part of a combustion chamber is sealed at the lower part of the hot water tank, a fume pipe is arranged inside the hot water tank, the two ends of the fume pipe are communicated with the combustion chamber and an outlet of a smoke discharging pipe of the coal-fired boiler respectively, an air inlet and an air outlet of a heat transmission pipe coiled inside the hot water tank are communicated with the combustion chamber and the air inlet of a draught fan respectively, the air outlet of the draught fan is communicated with the combustion chamber, a burner of the combustion chamber is opposite to a flamethrower outside the hot water tank, and the lower part of the combustion chamber serves as a dirt retention chamber. A scale discharging pipe is arranged at the bottom of the hot water tank, and a valve is arranged on the scale discharging pipe. The energy saver is applied to the coal-fired boiler.

Description

A kind of energy-saving appliance of coal-burning boiler
Technical field:
The present invention relates to a kind of boiler, particularly a kind of coal-fired energy-saving boiler.
Background technology:
Still contain not fully combustion product gases in the flue gas that existing coal-burning boiler is discharged, cause energy waste and contaminated environment.
Summary of the invention:
The object of the invention provides the energy-saving appliance of the burning boiler of a kind of energy savings and friendly environment.Technical scheme of the present invention is; It is characterized in that: coal-burning boiler is provided with boiler outward; The top seal of combustion chamber is in the bottom of said boiler, and fume pipe places said boiler, and the two ends of this fume pipe are communicated with the outlet of said combustion chamber and boiler exhaust gas pipe respectively; The air inlet and the gas outlet that are coiled in the heat-transfer pipe in the above-mentioned boiler are communicated with the air inlet of combustion chamber and air-introduced machine respectively; The gas outlet of said air-introduced machine is communicated with said combustion chamber, and the flame projector outside the bocca of said combustion chamber and the boiler is relative, and the bottom of said combustion chamber is the laying dust chamber.The bottom of said boiler is provided with draining dirt pipe, and this draining dirt pipe is provided with valve.The present invention and prior art relatively have energy-conservation and remarkable advantage friendly environment.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Elaborate in conjunction with following examples; Boiler 1 is set outside burning boiler; Upper and lower in this boiler one side is respectively equipped with outlet pipe and water inlet pipe, and the bottom of boiler is provided with draining dirt pipe, is equipped with valve on above-mentioned inlet tube and outlet tube and the draining dirt pipe.The top seal of combustion chamber 4 is in the bottom of boiler; The upper end of fume pipe 3 is communicated with the outlet of the smoke exhaust pipe of coal-burning boiler; Its lower end is communicated with the interior combustion chamber of boiler, and flame projector 5 is relative with the bocca 6 of above-mentioned combustion chamber, and the inlet, outlet of air-introduced machine 7 is communicated with the gas outlet and the combustion chamber of the heat-transfer pipe that is coiled in boiler 2 respectively; The bottom of above-mentioned combustion chamber is a dust storehouse, is provided with dedusting door to be opened/closed in the bottom of this dust storehouse.
Principle of the present invention is that the flue gas in the coal-burning boiler smoke exhaust pipe is delivered in the combustion chamber by air-introduced machine; Flame projector sprays into flame to the combustion chamber, and the high-temperature gas that the carbon monoxide that burns incompletely in the gas fume of combustion chamber and particulate coal dust firing are produced is given the water in the boiler through heat-transfer pipe with thermal energy conduction, sends in the boiler again; Thereby energy savings; In combustion process, high-temperature fuel gas temperature in heat-transfer pipe back that descends forms negative pressure, thus air can be constantly from bocca to the combustion chamber supplemental oxygen.Cigarette amount in the discharged flue gas reduces, friendly environment more, and after water heated up in this water tank simultaneously, the magnesium calcium ion in the water was tentatively separated the draining dirt pipe discharge from water tank from water, thereby had alleviated the fouling burden of boiler.

Claims (2)
