In mid-June this year, Hebei Province issued a notice regarding the development of gas-fired boiler nitrogen oxides (referred to as NOx) governance, in order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, will gradually nitrogen oxides exceeded boiler discharged for investigation and control work, high nitrogen oxide emissions from the original (150mg / Nm3 or above) is reduced to 30mg / Nm3. City, Hebei Province is located in the Yili Dairy Co., Ltd. to respond positively to governance EPA gas boiler NOx reduction, and led the way, three of the company's existing 15 steam tons / hour (t / h) gas steam boilers for low-nitrogen emissions transformation.

Most food processing facilities have industrial steam boilers or coal fired single drum hot water boilers for generating steam or hot water for processing, cooking, or sanitation. Coal, fuel oil, and natural gas are the major fossil fuels used by food industry boilers.

Water tube boiler in Malaysia

After statistics, we found that water tube boilers are a very popular type of furnace in Malaysia, especially biomass boilers. The water tube boiler is a boiler in which water, steam or steam-water mixture flows in the pipe while flame or smoke burns and flows outside the pipe. If the fuel is coal or biomass, the water tube boiler type is SZL double drum type or DHL corner tube type, if the fuel is gas or diesel, the SZS double drum is main type.

A: Commercial current commercial gas boiler main use is for supermarkets, hospitals, schools, hotels, residential (mainly the center of the city, convenient gas facilities area), bath, etc., to provide heating or bathing water, hot water. Since the gas in the ash, low sulfur and nitrogen than coal combustion, very small amount of dust in the flue gas, the state emission standards easy to achieve the required gas appliance, it can greatly reduce the pollution of the environment, environmental performance it is good. Boilers and combustion gas on the accessory device does not require gas, slag, dust removal machines, etc. grate, boiler investment saving equipment, is therefore suitable for commercial applications. Two: with factory workers using direct gas boiler piped gas powered, no gas storage, health conditions, can greatly reduce labor intensity and improve working conditions and reduce the operating cost, operating cost savings, space and labor . Since the smoke pollution, convection bank bear little corrosion, heat transfer effect, strong radiation heat, exhaust gas temperature is low, the thermal efficiency is significantly improved, so the main industrial gas boiler for power generation, industrial gas boilers of gas used may be generally natural gas, blast furnace gas, producer gas and so on. Three: Civil domestic gas boilers (boiler) is mainly used for daily household hot water, bath and hot water heating. In reducing equipment maintenance, gas burning boilers coefficient simple equipment, thus requiring less maintenance equipment maintenance, long life heated tube, gas boiler is simple to operate and easy to achieve automatic control.
