Gas procedure of passivation in coal fired boiler gradually replace coal-fired boilers become the new main market: Due to the characteristics of the resource structure of our country, the proportion of coal resource structure had relatively large, coal-fired boiler was once standing in the market significantly. But with the recent changes in the structure of resources, as well as countries in recent years greatly improved Huanjingwuran situation, gas boilers With environmental protection, pollution-free natural advantage is gradually replacing coal-fired boilers, has become the new main market. Ding boiler is also actively respond to national call, to the gas boiler to transform, optimize, following the Central senior professionals tripod boilers for everyone to resolve the next several advantages and economic benefits of gas-fired boiler.
Since the combustion of natural gas itself is adequate, and clean burning, non-polluting emissions is a more environmentally friendly energy sources. After coal combustion emissions from sulfur, more ash, environmental pollution more serious, which is incomparable with gas boiler. Gas boiler can bring greater environmental benefits to the enterprise.
There are many coal fired procedure of passivation in coal fired boiler manufacturer in China. ZG Boiler in China, has more than 70 years experience in boiler manufacturing and designs. And our products includes gas fired boiler, oil fired boiler, lph boiler, chain grate boiler, biomass fired boiler stoker, cfb boiler, etc.
Fast procedure of passivation in coal fired boiler in gas boiler industry has been at the leading level for low nitrogen environmental aspects of deep research. Dingzhou Yili Dairy determined after reaching cooperation with our company, launched a work plan for the boiler low-nitrogen transformation. Yili Dairy Dingzhou three original boiler 15t / h gas steam boiler, NOx emissions have reached 150mg / Nm3, belonging to the boiler equipment far exceeded. After the party fast professional and technical engineers, boiler and boiler model parameters to fully understand the components, rapidly developed a specific rehabilitation programs, start from the combustion system to achieve NOx emissions of 30mg / Nm3 to meet the most stringent environmental standards of the atmosphere.
IS PASSIVATION REQUIRED FOR NEW BOILERS. Magnetite that is formed as part of the passivation process protects the tube surfaces from further atmospheric corrosion (provided there is no contact with oxygenated water during storage of the heat exchanger) and corrosion after the heat exchanger is placed into service.Get a Quote
