Boilers can fully combust with low oxygen content accordingly. Moreover, by using the technology of catalyzed combustion, it is efficient to avoid many emissions such as CO and NOx. CO content in exhausted fumes is below 60ppm and NOx is below 40ppm. The emission of Co is much less which is only 1/10 of the national standard. And emission of NOx reaches level 5 of the European standard which is less than 50 ppm. China Hot Sell Wall Mounted Conventional Central Heating Gas Boiler
Gas and air are mixed fully before combustion so that the overplus air coefficient is between 1.1-1.3. Boilers can fully combust with low oxygen content accordingly. Moreover, by using the technology of catalyzed combustion, it is efficient to avoid many emissions such as CO and NOx. CO content in exhausted fumes is below 60ppm and NOx is below 40ppm. The emission of Co is much less which is only 1/10 of the national standard. And emission of NOx reaches level 5 of the European standard which is less than 50 ppm.
