Description
Technical field
The utility model relates to and belongs to energy-conserving and environment-protective field, particularly split fired steam boiler, specifically when not affecting boiler load, reducing the consumption of natural gas, reducing the exhaust temperature of flue gas.
Background technology
In society now, energy-conservation " the 5th energy " become after coal, electric power, oil, natural gas.The efficiency of natural gas boiler can reach about 90%, but because the expensive of natural gas (is approximately 1.5 times of light oil, 5 times of coal), so it is still extremely important how to improve natural gas boiler efficiency further, and to reduce heat loss due to exhaust gas in existing boiler design be improve the principal element of boiler efficiency, so the waste heat how in recovered flue gas is the key promoting boiler efficiency further.
At present, the exhaust gas temperature of gas-steam boiler common on market generally reaches 150 DEG C ~ 250 DEG C, and heat loss due to exhaust gas reaches more than 20%, causes the waste of resource to a great extent.In addition, after combustion of natural gas flue gas in contained nitrogen oxide and oxysulfide have pollution to air, although be qualified discharge with the nitrogen oxide of the single boiler of existing standard specification, but along with the continuous increase of boiler quantity, its total amount being discharged into the nitrogen oxide in air is also in increase, produce certain impact by the air of specific region, very possible needs in some region in the future improves standard limit of smog release.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of split combustion type gas steam boiler gas saving system is provided, reduce the exhaust temperature of flue gas, reduce the discharge of nitrogen oxide, make full use of the heat that flue gas discharges, use the technology of heat exchange of heat pipe, utilize the new wind of fume afterheat preheating, reduce the consumption of natural gas, economize on resources to reach, the object of emissions reduction.
The purpose of this utility model is achieved in that a kind of split combustion type gas steam boiler gas saving system, it comprises gas-steam boiler, heat exchange of heat pipe and chimney, the blower fan for introducing the new wind of low temperature is connected with at the flue entrance of heat exchange of heat pipe cold side end, the heat exchange of heat pipe exit position be connected with this flue entrance is connected with split burner, the described gas outlet of split burner is connected with the air inlet of gas-steam boiler, the gas outlet of described gas-steam boiler is connected with energy-saving appliance, the gas outlet of this energy-saving appliance is connected with the hot side flue entrance of heat exchange of heat pipe, the heat exchange of heat pipe be connected with this hot side flue entrance exports and is connected with chimney.
Compared with prior art, the beneficial effects of the utility model are:
The utility model split combustion type gas steam boiler gas saving system, make full use of the heat that steam boiler flue gas discharges, heat the new wind into steam boiler, when not affecting steam boiler load, decrease the consumption of natural gas, reduce the exhaust temperature of flue gas simultaneously, well reach the effect of energy-saving and emission-reduction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
Gas-steam boiler 1, heat exchange of heat pipe 2, chimney 3, blower fan 4, split burner 5, energy-saving appliance 6.
Detailed description of the invention
See Fig. 1, the utility model relates to a kind of split combustion type gas steam boiler gas saving system, comprise gas-steam boiler 1, heat exchange of heat pipe 2 and chimney 3, the blower fan 4 for introducing the new wind of low temperature is connected with at the flue entrance of heat exchange of heat pipe 2 cold side end, heat exchange of heat pipe 2 exit position be connected with this flue entrance is connected with split burner 5, the gas outlet of described split burner 5 is connected with the air inlet of gas-steam boiler 1, the gas outlet of described gas-steam boiler 1 is connected with energy-saving appliance 6, the gas outlet of this energy-saving appliance 6 is connected with the hot side flue entrance of heat exchange of heat pipe 2, the heat exchange of heat pipe 2 be connected with this hot side flue entrance exports and is connected with chimney 3, gas-steam boiler operationally, produce a large amount of flue gases, flue gas is T1=130 DEG C by temperature after energy-saving appliance, flue gas is by being connected to the flue of the hot side of heat exchange of heat pipe, high-temperature flue gas is by after heat exchange of heat pipe, new air temperature T3=-10 DEG C-40 DEG C, the new wind of low temperature is heated to form T4=70 DEG C, then discharged by chimney, the new wind that steam boiler needs, temperature is T3=-10 DEG C ~ 40 DEG C, by the blower fan air inducing effect of Split type combustion device, heat exchange of heat pipe is introduced by the flue being connected to heat exchange of heat pipe cold side end, the new wind of low temperature is heated to form T4=70 DEG C, then enter Split type combustion device unit, with after fuel mix, heating flame is carried out to steam boiler.
