Installation of fuel gas-fired boiler safety valve safety valve is one of the important requirements of the protection device fuel gas-fired boiler, boiler user is necessary for proper installation of the safety valve. Following small talk to the fuel gas boiler safety valve installation points: (1) greater than the rated 0.5t h fuel gas boiler / evaporator, at least two safety valves installed; equal to or less than the rated evaporation 0.5t / h fuel gas-fired boiler, at least install a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed. (2) safety valve should be mounted vertically at the highest position boiler drum, collection tank. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. (3) have lever-type safety valve means for preventing movement of the self-weight and deviant restriction lever guides the spring loaded 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 boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. (5) safety valve boiler tubes, which 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, short tube passage area not less than 1.25 times the area of all the exhaust valve. (6) 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. Safety valve exhaust pipe at the bottom should be fitted to the safe location of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.
The technology also has the potential to redirect some regional energy economies from liquid fuels to locally sourced energy such as diesel oil, heavy oil, light oil, which has been accumulating in the Pakistan. As to oil refining, our packaged boiler can supply 10 ton steam per hour as designed.
PM2.5 is frequently mentioned in recent years, and its main premise was that the formation of NOx, according to the latest research results show in Beijing, PM2.5 and NOx emissions due to the formation of more than 50% of the total proportion of PM2.5. Because of a large area of coal to gas projects in recent years, the country's use of gas-fired boiler more than 50 million units in the Beijing area, gas boiler emissions will soon exceed the vehicle, as the primary sources of NOx in Beijing, so Beijing EPA first proposed the strict NOx emission standards: Beijing new boiler to perform emission limit of 30 mg / standard cubic meter for boilers with high-pollution fuel combustion zone ban, the implementation of emission limit 80 mg / standard cubic meter . The standard is much higher than the European emission standards for boilers, to the world's most demanding emissions standards in Southern California to move closer to the boiler.
Second, premix condensing boiler, that is, many professionals say the real condensation. This boiler design depth total condensation on the use of the early art, can achieve high thermal efficiency of 108%; With frequency premix combustion technology, energy than conventional gas boiler 40% of nitrogen oxide emissions below 30 mg / cubic, energy saving effect is very obvious. These advanced technologies make the first premix condensing boiler is higher than a lot of false condensing boiler, it takes about one year to recover the cost of investment and more.
Open all the water taps fully to drain down the system after removing any bath, basin and sink plugs. Close the taps when the water flow ceases. Add the recommended quantity of commercial lime scale remover to the cold water storage tank. (If you have a combi boiler without a tank you may have to remove the heat exchanger and descale it directly.)Get A Quote
