Industrial Fully Automatic steam boiler 8 ton Brunei

Mining plant become more and more important for many country’s economic development.So how to improve the mining efficiency is a focus question.The mining efficiency have improved significance since biomass CFB boiler applied in mining industry.

Fuel volume adjustment simple mechanical atomization nozzle adjustment range is usually only 10% to 20%. When the boiler load changes little, the oil pressure in front of the boiler can be adjusted by changing the oil pressure before the furnace, and the purpose of increasing the oil pressure can be achieved by increasing the oil pressure. When the boiler load changes greatly, the atomization plate with different aperture can be replaced to increase and decrease the fuel injection. When the boiler load changes greatly, neither of the two adjustment methods can adapt to the requirements, so it is necessary to change the fuel injection quantity by increasing and reducing the number of fuel nozzles. The adjustable range of the atomizing nozzle of the return oil machine is relatively large. When the boiler load changes, the return valve opening can be adjusted accordingly to change the return oil quantity. Return oil The larger the quantity, the smaller the injection quantity; on the other hand, the fuel injection quantity increases. In normal operation, the fuel quantity shall not be increased or reduced sharply, so as not to cause the sharp change of combustion, and cause the pressure element to expand and shrink abruptly and damage.

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. "

Before pickling, the boiler should take the representative scale samples to test and formulate the cleaning plan. The corrosion index sheet should be hung in the boiler and the acid box at the beginning of the acid injection (until the acid is removed), and the corrosion index plate shall be put into the boiler and the acid box at the beginning of the acid injection. The technological process of pickling and the temperature, concentration, flow rate and time of the pickling solution should be carried out and controlled according to the cleaning scheme, and the samples and tests should be continuously taken and recorded during the cleaning process. After cleaning, use furnace unit, cleaning unit and boiler safety supervision department to check and accept the cleaning quality.
