After the impact the transformation of low nitrogen gas boiler

Environmental protection has intensified, the provinces and cities have introduced various environmental policies. Air pollutant emissions is one of the main issues of governance and environmental protection sectors. For gas-fired boilers for low-nitrogen transformation has also become popular, such as Beijing, Tianjin, Zhengzhou, Xi'an and other places are carrying out renovation work and out of the boiler.

Gas boiler furnaces and cooking formal operation of the boiler furnace 1, and its object is to clear the body of the boiler impurities, grease and rust. The inspection of boiler installed and cold test run, each member confirms perfect safety conditions have hot start operation to start cooking stove. 2, boiling out dosage (see table below) Unit: kg / t rust grease Drug Name Notes thicker thin rust grease sodium hydroxide (NaOH) 2 ~ 33 ~ 4 trisodium phosphate (Na3PO412H2O) 2 ~ 33 ~ 4 when no trisodium phosphate, sodium carbonate can be used (of Na2CO3) in place of an amount of 3 to 6 kg / t water. 3, when dosing, the low water level in the boiler water should, boiler water should be the highest level, the drug was added on the stove interfaces (e.g., valve opening) when the cooking stove. 4, the end of the cook should the boiler furnace pressure was kept at about 75% of the working pressure, time is generally 2 to 3 days. 5, during the cooking stove, boiler water periodically take laboratory analysis, alkalinity boiler water of not less than 45 meq / L, should be added or dosing. 6, oven cooking is completed, the drum and the current tank should be cleaned precipitate, rinsing the boiler and in contact with the agent through a valve, to check whether or clogging sewage. 7, after cooling boiler, furnace water will be fully released. Open manholes, hand holes, repeatedly washed with water until the furnace no rust, grease qualified. (Ix) a test run, the test run should be with a load, for 4 to 24 hours (set maximum, minimum operating pressure). 2, observe the safety valve and various safety accessories, protective devices and other operations are sensitive and reliable. 3, after the commissioning of qualified, supervisory inspection agency should be acceptance.

Ordinary gas boiler obvious advantage is the relatively low price, which is most of the reason customers choose it. Just use the boiler is not mandatory for low nitrogen emissions, you can directly select the ordinary gas boiler, this enterprise is also very friendly.

Still 8 cultural and creative industrial park is located in the Chaoyang District, Beijing, Bali Zhuang Chen Lin, No. 2, construction area of ​​493,300 square meters. Surrounded by quintessence of Court, Red Sandalwood Museum, Shanxi Museum and other famous attractions. Due to its special geographical location, has very stringent requirements for providing heat boiler plants. Carefully selected to finalize cooperation with our company, signed a two He Lide series complete condensation pressure hot water boiler.
