afbc boiler bed material density

Gas afbc boiler bed material density 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.

The main method to extend the life of the condensing afbc boiler bed material density - Regular maintenance: condensing boiler flue gas heat recovery through the use of technology to achieve high thermal efficiency and operational efficiency of traditional boilers can not be achieved, in recent years has been widely loved and accepted by the user and the market. After the user bought condensing boilers not only pay attention to the safety of the boiler running smoothly, but also to carry out regular maintenance, so that the boiler has a more long life. So, when people use condensing boiler maintenance matters which should pay attention to it?

The recent introduction of some cities air pollutant emission standards, it is this hot climax. Beijing, Shaanxi, Henan and other provinces and cities as the representative of the region, the development of new afbc boiler bed material density unprecedented stringent requirements - nitrogen oxide emissions to below 30 mg / m (included), and coal-fired boiler for different capacities apply different remediation measures, or eliminated, or modified. The ordinary gas boiler can not meet the current requirements of nitrogen oxide emissions in the future, China will gradually for more cities to the popularity of nitrogen oxide emissions below 30 mg / m (included) policy requirements, this low nitrogen boiler derivative.

After use throughout the winter, the Central Conservatory of Music give us feedback, six V6-99 fully meet the heating needs of the school. And afbc boiler bed material density fuel and water requirements are not high, urban water and low-pressure natural gas combustion can operate. The most important point is that nitrogen oxide emissions are very low and very happy to recommend it to others to do the brother of boiler units. --customer feedback
