4 ton coal fired boiler China

To continue to improve air quality and protect people's lives and health, Hainan Province, issued a "Hainan Air Pollution Prevention Regulations" (hereinafter referred to as "Regulations"), a clear implementation of the total coal consumption control system, and gradually reduce the amount of coal consumption, phase out existing coal-fired units. "Regulations" since March 1, 2019 into effect.

"Regulations" put forward specific requirements for coal and other energy pollution control.

A prohibited import, sale and burning of coal does not meet quality standards; prohibited the import, sales do not meet standards of quality petroleum coke; prohibition of burning petroleum coke. Above the county level department in charge of market supervision and management need to be strengthened coal, petroleum coke quality management, from time to time on coal, petroleum coke quality sampling.

Second, the people's government above the county level market supervision and administration departments shall, jointly with relevant departments in charge of the environment, industry and information technology, etc. According to China's Hainan Province and the relevant provisions to strengthen the supervision and management of boiler production, import, sale, use, etc., do not compliance with environmental standards or requirements shall not manufacture, import, sale and use. Phasing out coal-fired boilers. Existing clean energy such as natural gas-fired boilers, furnaces, low NOx combustion should be completed within the prescribed period of transformation of the people's governments above the county level department in charge of the ecological environment. New clean energy such as natural gas-fired boilers, furnaces and other facilities shall pollution control measures such as the use of low NOx combustion.

Third, the central heating has been implemented for the work (production) business park, a ban on new construction, renovation, expansion of decentralized heating boilers, heating boilers should be dispersed in the original city, county, autonomous county people's government department in charge of market supervision prescribed period in the demolition; work not yet implemented central heating (production) business park has heating demand should be in the city, county, central heating implementation as soon as possible within the time limit prescribed Autonomous County people's government department in charge of market supervision and management, and removal of the original dispersion heating boilers.

Coal dust fire type biomass power plant 4 ton coal fired boiler china type

In the power generation industry, the most common biomass combustion technologies fall into three categories: stoker/grate firing, fluidized bed combustion (FBC)—including circulating fluidized bed (CFB) and bubbling fluidized bed (BFB) boilers—and suspension firing or pulverized fuel (PF) firing.

A bunch of factors that cause pressure cast iron 4 ton coal fired boiler china efficiency China have occurred in high-profile coal to natural gas operation, cast iron boiler should be transported, greatly avoid dust contamination, smoke and harmful gases such as nitric oxide are also under control. Efficiency is the key measure of regular cast iron boilers, let you research a bunch of factors that cause the cast iron boiler efficiency under pressure. Through the study of relevant departments, cast iron boilers heat loss is mainly due to bear with these two places: the proportion of full combustion air flue gas emissions related to unreasonable waste heat. Reduce flue gas emission waste heat boiler can be installed in a cast iron terminal fume fever recycled back into the formation, or should be shipped condensing boilers more advanced functions. Combustion air ratio sufficient unreasonable unsuitable Summary: ejector ordinary cast iron boiler burner, air-formed flexible scheduling can not occur. Many non-automatic blower cast iron boiler burners, creating factors that cause unreasonable fuel ratio are the following: the main air-fuel ratio unreasonable inclusion can be divided into two conditions: when the airflow excess, having endless excess cool air is heating, creating a cast iron boiler operating costs increase, reduced cast iron boiler efficiency; when the airflow of non-compliance, will reveal the phenomenon is not completely lit, cast iron boiler efficiency appears weakened.

Boiler load operation of the harm it often happens that the 4 ton coal fired boiler china load operation in daily production, a lot of people disagree to this phenomenon, Xiao Bian today to tell you about the hazards boiler load operation. 1, the normal production Effect: combustion instability, its volatile bed temperature, is not easy to adjust the bed temperature to be low temperature, difficult to adjust the control returns, may cause misfire. 2, the life of heat exchange tubes inside the boiler Effect: low load combustion, and will return to coal ash into uneven, resulting in uneven heating heat exchange tubes, pipes easily lead to local overheating, causing overheating of the wall, a long time run will increase the chance of occurrence of burst pipes. 3, the impact of the boiler thermal efficiency: low furnace temperature will cause incomplete combustion, boiler efficiency will go down. 4, increase the heat exchange tubes of corrosion tail: long-term low-load operation, the exhaust gas temperature will decline, low-temperature corrosion tail arrangement of the heat exchange tubes of the probability of occurrence increases. These are the hazards boiler load operation, I hope this can help you. To learn more about the boiler, please continue to focus on this site.
