6 Ton Gas Fired Boiler Suppliers

Are gas-fired steam 6 ton fired boiler supplierss environmentally friendly? Gas-fired steam boiler, which can be regarded as a gas-fired boiler, can also be regarded as a steam boiler. This boiler, from a professional point of view, is an environmentally friendly boiler, compared to oil and coal-fired boilers, because it uses gas. Moreover, the thermal efficiency of this kind of boiler is very high, can reach more than 90%.

March 26, 2018, fast Boiler Marketing Summit successfully held in Anyang, excellent strategic partner dealers across the country gathered in beautiful surroundings Huan Gulf Hotel venue center, witnessed ups and downs square almost 20 years, complicity future development plans.

1, the safety valve should be mounted vertically in a high position in the pot business, set box.

2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve.

3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly.

4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm.

5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of ​​the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of ​​the passage should not step short tube to 1.25 times the area of ​​all the exhaust valve.

6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust.

7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.

8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve.

How to put ordinary gas 6 ton fired boiler suppliers boiler emissions become low nitrogen boiler is an important cause of air pollution in order to reduce pollution of the boiler, in the country minus the cancellation of coal coal have done a lot of work, which significantly reduces the solid boiler soot emissions and sulfur dioxide emissions of polluting gases. But only coal-fired boilers will be replaced by gas-fired boilers, boiler did not reduce emissions of nitrogen oxides, so the boiler with a new task becomes low nitrogen boiler boiler also became current. In the end what is low nitrogen boiler? In many areas, there is no mandatory use of low nitrogen boiler regulations, and in Beijing, mandatory use of low nitrogen requirements of the boiler has been formally introduced in April 1 this year, the existing boiler will perform the following 80mg standard, the new boiler will perform the following criteria 30mg, 80mg and standard criteria will gradually be replaced by 30mg of the boiler, and therefore in Beijing, boiler NOx emissions less than 30mg in order to become a low-nitrogen boiler. In Henan, the new gas-fired boiler will also perform the following criteria 30mg of nitrogen oxides, we can safely predict that the future low nitrogen boiler will be large-scale promotion. At this stage, a lot of nitrogen oxide emissions from gas-fired boiler in 150mg or less, which is far unable to meet the standard low-nitrogen boiler. Ordinary means into a low nitrogen gas boiler with a boiler or low nitrogen transformation replace the original boiler is condensed into nitrogen oxides emissions below 30mg (formula) boiler. Nitrogen mainly low boiler transformation replace Burner, mainly in the following ways: 1, flue gas recirculation transformation (Ultra Low NOx) is the use of combustion air head, the part of the combustion fumes sucked back into burner, and combustion air mixture. Since the flue gas recirculation, the combustion fumes a large heat capacity, the combustion temperature is lowered, the NOx reduction. Another recirculation burner itself is directly recycled into the part of the fumes inside the burner and to the combustion process, the burner has such a suppression effect of nitric oxide and the double energy. 2, the premix burner (combustion surface) technology premix gas burner, the gas and air are thoroughly pre-mixed prior to entering the combustion chamber, so that more complete combustion, improve the combustion efficiency and reduce harmful emissions, but also can reduce the space requirements of the combustion chamber, is currently the most advanced of a gas combustion technology. Due to the low NOx combustion boiler renovation and diverse, sophisticated technology, in order to ensure the smooth implementation of the transformation, effectively preventing security risks, prevent accidents, analysis and appraisal by experts, comprehensive security, environmental factors, Beijing and the Beijing Municipal Environmental Quality and Technical Supervision protection Bureau jointly issued a notice :( a) for 7.0mw (evaporation 10t / h) or more in the boiler is not recommended transformation of the way premixed combustion. (B) to the central back-fired boilers, the transformation is not recommended way to replace the burner. (C) For boilers, does not recommend the use of direct transformation of the way the transformation of the burner. Therefore, a low nitrogen transformation process boiler, more often, is a direct replacement for the original gas boiler low nitrogen boiler.
