Abstract
The utility model relates to an oxygen-enriched combustion boiler system which comprises an oxygen-enriched box (3) connected between a nitrogen-making machine (1) and a hearth (2) and used for collecting exhaust of the nitrogen-making machine (1); a pressure machine (4) is arranged between the oxygen-enriched box (3) and the hearth (2), so that the exhaust is led into the hearth (2). By the aid of the exhaust of the nitrogen-making machine, oxygen-enriched combustion of a boiler is realized, and oxygen-enriched resources discharged through the nitrogen-making machine is reasonably utilized.
Description
Technical field
The utility model relates to efficient burning technology, is specifically related to a kind of system of boiler oxygen-enriched combusting.
Background technology
Oxygen-enriched combusting refers to use than common air (containing the oxygen 21%) oxygen-enriched air that oxygen concentration is high and burns, and it is an energy-efficient combustion technology, all has application in glass industry, metallurgical industry and Thermal Power Engineering Field.In boiler, adopt oxygen-enriched combusting, can reduce the ignition temperature of fuel and reduce the tail-off time, reduce exhaust gas volumn and flue gas loss, improve boiler efficiency.But employing oxygen-enriched combusting, needs oxygen-enriched generator (comprising that deep cooling, omnibus control system or film separate oxygen) conventionally, consume certain energy, has limited applying of this technology.
Utility model content
The purpose of this utility model is to provide a kind ofly makes rational use of resources and the energy, realizes the system of boiler oxygen-enriched combusting.
The system of the boiler oxygen-enriched combusting that the utility model provides, comprises the oxygen enrichment case 3 being connected between nitrogen producing equipment 1 and burner hearth 2, for collecting the exhaust of nitrogen producing equipment 1; Between oxygen enrichment case 3 and burner hearth 2, pressuring machine 4 is set, makes exhaust pass into burner hearth 2.
As improvement, respiratory siphon 8 is set on oxygen enrichment case 3 oxygen enrichment case 3 is communicated with atmosphere.
As improvement, the utility model also arranges nozzle 6 makes the exhaust of nitrogen producing equipment 1 spray into burner hearth 2 by nozzle 6.
As improvement, between pressuring machine 4 and burner hearth 2, control valve 5 is set, for adjusting gas flow.
In nitrogen production process, using airborne nitrogen as product enrichment, in the exhaust of nitrogen producing equipment (as Nitrogen Station), because nitrogen gas concn greatly reduces, correspondingly oxygen has obtained enrichment (oxygen concentration is in 40% left and right), this part oxygen enrichment resource is not utilized conventionally, is directly discharged in environment and has gone.The utility model combines boiler and nitrogen producing equipment effectively, utilizes the exhaust (oxygen enrichment) of nitrogen producing equipment, realizes the oxygen-enriched combusting of boiler, has rationally utilized the oxygen enrichment resource of nitrogen producing equipment discharge.
The exhaust gas collection of nitrogen producing equipment is arrived oxygen enrichment case by the utility model, then after pressurization, pass into the burner hearth of boiler, improves oxygen concentration in burner hearth, reduces exhaust gas volumn (being mainly to have reduced the nitrogen amount in flue gas), and overheavy firing, has improved boiler efficiency.
Brief description of the drawings
Accompanying drawing 1 is the system schematic of the utility model boiler oxygen-enriched combusting.
Detailed description of the invention
As shown in Figure 1, the system of the boiler oxygen-enriched combusting that the utility model provides, comprise the oxygen enrichment case 3 between delivery pipe and the boiler furnace 2 that is connected in nitrogen producing equipment (as Nitrogen Station) 1, pressuring machine 4 is connected between oxygen enrichment case 3 and boiler furnace 2, and above-mentioned each equipment connects with carrier pipe 7.
The course of work of the present utility model is as follows: the exhaust (oxygen enrichment) of nitrogen producing equipment 1 imports oxygen enrichment case 3 by carrier pipe 7, after being pressurizeed, passes in boiler furnace 2 by pressuring machine 4, realizes the oxygen-enriched combusting of boiler.
The end that connects boiler furnace 2 at carrier pipe 7 arranges nozzle 6, after oxygen enrichment pressurization, sprays in boiler furnace 2 by nozzle 6, can further improve efficiency of combustion.
Can between pressuring machine 4 and boiler furnace 2, control valve 5 be set, to regulate the Rich Oxygen Amount that enters boiler furnace 2.
Respiratory siphon 8 can be set on oxygen enrichment case 3, oxygen enrichment case 3 is communicated with atmosphere.Balance between the capacity of nitrogen producing equipment 1 and boiler oxygen enrichment demand realizes by respiratory siphon 8, in the time that the capacity of nitrogen producing equipment 1 is greater than boiler oxygen enrichment demand, the interior malleation that occurs of oxygen enrichment case 3, rich exhaust enters atmosphere automatically by the respiratory siphon 8 on oxygen enrichment case 3, ensures the safety in production of nitrogen producing equipment 1; In the time that the capacity of nitrogen producing equipment 1 is less than boiler oxygen enrichment demand, the interior negative pressure that occurs of oxygen enrichment case 3, the air in environment fills into oxygen enrichment case 3 automatically by the respiratory siphon 8 on oxygen enrichment case 3, ensures the stable operation of boiler.
Claims (5)
1. a system for boiler oxygen-enriched combusting, is characterized in that this system comprises the oxygen enrichment case (3) being connected between nitrogen producing equipment (1) and burner hearth (2), for collecting the exhaust of nitrogen producing equipment (1); Between oxygen enrichment case (3) and burner hearth (2), pressuring machine (4) is set, makes exhaust pass into burner hearth (2).
