Circulating Fluidized Bed combustion is a comparatively new technology that has given boiler and power plant operators a greater flexibility in burning a wide range of fuels. How is this different from the more widely used Pulverized Coal Combustion?

10th June this year, the provincial government agrees that the ecological environment in Zhejiang Province Office issued the "Notice on the implementation of special emission limits national emission standards of air pollutants" (hereinafter referred to as "notice"), marking the full implementation of Zhejiang Province especially national emission limits of air pollutants.

"Special emission limits" is mainly for land development density is already high, the environment carrying capacity began to weaken, or less atmospheric environmental capacity, ecological environment is fragile, more stringent prone to serious air pollution problems in sensitive areas and set the emission limits. Implementation of the national emission standards for special emission limits, Zhejiang Province in favor of further strict pollution management, reduce pollutant emissions, to further improve air quality, but also help promote the integration of the Yangtze River Delta environmental standards.

In fact, back in 2013, Zhejiang has already begun in some areas particularly the implementation of the national emission standards limit emissions of air pollutants, but was limited to Hangzhou, Ningbo, Huzhou, Jiaxing and Shaoxing, Hangzhou Bay five cities; and this is to expand to the province level. In addition to a wider geographical range, "advertisement" clearer pollutant emissions targets, e.g., volatile organic contaminants not individual indicators, including not only non-methane hydrocarbons, total volatile organic compounds such as benzene, benzene and other pollutants indicators meet the definition of volatile organic compounds should be performed; also more involved in the industry, such as boilers only provides original coal-fired boiler, and "notice" it covers all types of boilers (including oil, gas).

It is reported that, in the national emission standards have been implemented, a total of 25 standards set emission limits of air pollutants in particular; at the same time, the recent ecological Ministry of Environment and the State Administration of market regulation has released three national emission standards of air pollutants, namely, pharmaceuticals, paints, inks and adhesives and volatile organic compounds fugitive emission control standards, and will be from July 1, 2019 implementation. According to "notice" requirement, the province is also involved in the enterprise should implement special emission limits specified in the three standards, the execution time of the emission standards time synchronization. Provincial Department of Atmospheric environment Department official said: "The implementation of the national emission standards for emission limits in particular, help to further strict management of our province pollution, reduce pollutant emissions, to further improve air quality, but also help promote environmental protection in Yangtze River Delta standard integration. "

If you want to make six tons of gas steam boiler manufacturing machine price normal operation, it is important to note several points: 6 tons of gas steam boiler is a lot of kinetic energy equipment production and processing industry can not do without, users choose to fit their own businesses steam boiler plant, but also master the method so that the normal operation of the boiler, so as to ensure that the boiler to achieve long life.

Maintenance of common gas boiler you buy boiler equipment, will pay attention to a lot of problems, the number of thermal efficiency, energy saving and environmental protection whether, if the boiler manufacturers have to install special equipment manufacturing license, etc., are all you need to pay attention to the selection of points. But at the same time, the boiler in the course of regular maintenance is also very important. Regular maintenance of the gas boiler, can effectively extend the life of the boiler, improve work efficiency boilers, low failure rate, is conducive to the normal safe operation of the boiler. After regular maintenance gas-fired boiler, life, energy efficiency and the failure rate of maintenance should be carried out regular maintenance of the boiler better (especially boiler has been running for more than one year) than those without. Conventional boiler maintenance methods are: pressure maintenance, maintenance wet, dry maintenance, maintenance inflated. A pressure maintenance using pressure maintenance shutdown time does not exceed one week. Before the system shutdown process terminates filled with water to make soft drinks, is to maintain the residual pressure 0.05 ~ 0.1MPa, boiler water is maintained at a temperature above 100 deg.] C, can effectively prevent air from entering the boiler. Second, wet wet maintenance shutdown maintenance time does not exceed one month. In the soda boiler water softener system cheerful note lye, leaving no vapor space. This is because a stable oxide film with an aqueous solution of a suitable alkalinity can be formed with the metal surface, thereby preventing corrosion. Third, using the dry method maintenance shutdown maintenance time is longer. This is done; pot of water put the net after shutdown, residual heat boiler using a drying furnace, timely removal of residual scale and pot residue was then placed on the tray containing a desiccant within the drum and grate, Finally, close all valves, manhole and hand hole door. Regular inspection and maintenance, and timely replacement of the desiccant failure. Fourth, inflated maintenance Inflatable maintenance shutdown can be used for long-term maintenance. After the boiler shutdown, do not turn on the water, the water level is maintained at the high water line, to take measures so that the boiler deoxidation, then the pot of water and isolated. After the ammonia gas or helium gas through the pressure after inflation is maintained at 0.2 ~ 0.3MPa, nitrogen combines with oxygen to generate nitrogen oxides, so that the oxygen can not be in contact with the steel plate; ammonia was dissolved in water such that the water is alkaline, can effectively prevent oxygen corrosion phenomenon.
