Abstract
The utility model discloses an economizer for a coal burning boiler. The technical scheme is as follows: a hot water tank is arranged outside the coal burning boiler; the upper part of a combustion chamber is sealed in the lower part of the hot water tank; a fume pipe is arranged in the hot water tank; both ends of the fume pipe are respectively communicated with the combustion chamber and an outlet of the boiler fume discharge pipe; an air inlet and an air outlet of a heat transfer pipe coiled in the hot water tank are respectively communicated with the combustion chamber and an air inlet of a draught fan; an air outlet of the draught fan is communicated with the combustion chamber; a flame nozzle of the combustion chamber is opposite a flame thrower outside the hot water tank; and the lower part of the combustion chamber is provided with a dust accumulation chamber. The bottom of the hot water tank is provided with a scale discharge pipe, and the scale discharge pipe is provided with a valve. The utility model is used for a coal burning boiler.
Description
Technical field:
The utility model 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 utility model purpose provides the energy-saving appliance of the burning boiler of a kind of energy savings and friendly environment.The technical scheme of the utility model 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 utility model and prior art relatively have energy-conservation and remarkable advantage friendly environment.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
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.
The principle of the utility model 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)
