The pipeline is provided with a preheating device for heating the air supply. The utility model uses the residual heat of the boiler and the drainage to heat the air supply, which not only improves the combustion efficiency, but also reduces energy waste.
Description
Technical field
The utility model relates to a kind of boiler, is specifically related to a kind of New-type boiler that has the preheating device of blowing.
Background technology
For guaranteeing steam quality, the above boiler of 10t/h generally is equipped with continuous blow off equipment, and the flash steam that in continuous blow off equipment, produces gets into the feedwater of oxygen-eliminating device heating boiler, and gets into trench from a large amount of high-temperature water that continuous blow off equipment is discharged, and causes the waste of the energy.Simultaneously, traditional boiler is provided with pressure fan, utilizing pressure fan air-supply in the body of heater to realize the abundant burning of fuel, improves efficiency of combustion, but pressure fan sends into is cold air, and with respect to hot-air, cold air reduces efficiency of combustion greatly.
The utility model content
The utility model technical problem to be solved provides a kind of New-type boiler that has the preheating device of blowing, its can with pressure fan send in the body of heater air heat in advance, improve efficiency of combustion, thereby eliminate defective in the above-mentioned background technology.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The New-type boiler that has the preheating device of blowing; Comprise the air supply duct that body of heater, the continuous blow off equipment that links to each other with body of heater, air outlet are installed on the pressure fan on the said body of heater and are communicated with said pressure fan, said air supply duct is provided with the preheating device that is used to heat air-supply.
As the design of routine, said preheating device can adopt firing equipments such as miniature boiler, and preheating device is installed on the upstream position of said pressure fan, with the air-supply heating that gets in the body of heater, has improved the efficiency of combustion of body of heater fuel.
As a kind of improvement, said preheating device is a gas-liquid heat-exchange, and said gas-liquid heat-exchange comprises housing and the heat exchanger tube that is arranged at enclosure interior.
As the design of routine, can feed hot water in the said heat exchanger tube, through heat exchange to temperature lower air-supply carry out preheating.
As a kind of further improvement, said heat exchanger tube is communicated with the outlet pipe of said continuous blow off equipment, and based on this structure, said heat exchanger tube can utilize the heating of will blowing of the waste heat of boiler platoon water, has not only improved efficiency of combustion, and has reduced energy waste.
The utility model has following beneficial effect owing to adopted above structure:
In the utility model, on the air supply duct of pressure fan, install and be used to heat the preheating device of air-supply, the air-supply that will get in the body of heater is heated, go into after the stove air is heated, can improve the efficiency of combustion of body of heater fuel.
In the utility model, preheating device adopts gas-liquid heat-exchange, and the heat exchanger tube of gas-liquid heat-exchange is communicated with the outlet pipe of continuous blowdown system of boiler device, can utilize the waste heat of boiler platoon water to give the air-supply heating, has reduced energy waste.
Description of drawings
Accompanying drawing is the utility model structural representation;
Among the figure: 1. body of heater, 2. continuous blow off equipment, 3. pressure fan, 4. gas-liquid heat-exchange, 5. air supply duct, 6. housing, 7. heat exchanger tube, 8. outlet pipe.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in accompanying drawing; The New-type boiler that has the preheating device of blowing; Comprise body of heater 1, be installed on the continuous blow off equipment 2 on the body of heater 1, the air supply duct 5 that the air-supply mouth of pipe is installed on the pressure fan 3 on the body of heater and is communicated with said pressure fan 3; It is characterized in that: also be provided with the preheating device that is used to heat air-supply, this preheating device adopts gas-liquid heat-exchange 4, and said gas-liquid heat-exchange 4 is installed on the said air supply duct 5; Said gas-liquid heat-exchange 4 comprises housing 6 and is arranged at housing 6 inside be used to the to circulate heat exchanger tube 7 of high-temp liquid that said heat exchanger tube 7 is communicated with the outlet pipe 8 of said continuous blow off equipment 2.
The principle of the utility model is following:
The flash steam that boiler produces in continuous blow off equipment 2 gets into the feedwater of oxygen-eliminating device heating boiler; And a large amount of high-temperature water of discharging from continuous blow off equipment 2; High-temperature water gets in the heat exchanger tube 7 of gas-liquid heat-exchange 4; Pressure fan 3 is sent into the air heat in the body of heater 1, and the air after the heating gets into body of heater 1 and participates in burning.The mode that this waste heat that utilizes boiler platoon water heats air-supply has not only improved efficiency of combustion, and has reduced energy waste.
The utility model is not limited to the above-mentioned specific embodiment, and all are based on the technical conceive of the utility model, and the structural improvement of having done all falls among the protection domain of the utility model.
