szl series coal fired short construction period boilers
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.
75ton h CFB szl series coal fired short construction period boilers
Circulating fluidized bed combustion technology mechanism research, has assumed the "research and test modeling and numerical simulation of large-scale circulating fluidized bed combustion system working process," nearly ten National Natural Science Foundation, the national "eight five" key project and "circulating fluidized bed gas-steam generation equipment research," national "Nine Five" project "75ton circulating fluidized bed package design," and the National Key Basic Research Development Program projects. In cooperation with Canadian institutions concerned a joint application to the Canadian International Development Agency CIDA Canadian project "Development Research burning coal combustion CFB China", made a series of achievements in scientific research, especially in the circulating fluidized bed combustion , heat transfer, desulfurization and other aspects of a deeper study, in cooperation with the United Technologies Corporation a "vortex fluidized bed combustion technology research", in cooperation with the US F & W company "a new gas-solid separation technology research." Cooperation with South Korea development of large-scale circulating fluidized bed boiler. In extensive research on the basis of the mechanism for circulating fluidized bed combustion technology with sufficient awareness, especially in the hydrodynamic characteristics of circulating fluidized bed, a circulating fluidized bed coal and special fuels (anthracite, coal, coal, raw biomass fuels, coal, petroleum coke, etc.) of the combustion characteristics of a circulating fluidized bed furnace heat transfer characteristics and tail heating surface, the control process pollutants (SO2, NOx and heavy metals) circulating fluidized bed combustion, circulating fluidized Key components such as splitters bed, feed back mechanism and external fluidized bed heat exchanger. The main fluidized bed combustion test rig owned are: cross-section of 200 × 200 high as cold circulating fluidized bed test stand 4000, cross-section of 200 × 200 high of 4000 circulating fluidized bed thermal test bench, sectional as high as 500 × 500 6000 circulating fluidized bed thermal test bench, cross-section of 350 × 350 high as 10,000 hot circulating fluidized bed test bed 1MW fluidized bed combustion test stand and vortex. In addition to research in the laboratory scale test rig performed, still 75t / h circulating fluidized bed boiler and 220t / h circulating fluidized bed boiler exhaustive testing, to obtain large flow boiler, combustion, heat transfer, pollutant Characteristics emissions.
Instead of gas-fired szl series coal fired short construction period boilers coal-fired boilers has become an inevitable trend of more and more common as the use of gas, China's energy structure has undergone tremendous changes. In the future for a long period of time, gas and coal is still the main source of energy, how to weigh the severity of it in small series for everyone here today about the analysis and comparison:? Although there are many drawbacks of coal-fired boilers, but in the national economic development has an irreplaceable role, he plays an important role in the past for a long time. Because all the advantages of gas-fired boiler, will become a major force in the development of national energy policy boiler. Instead of gas-fired boiler coal-fired boilers has become an inevitable trend. Coal-fired boilers are in a very long time the main products of heating, but there are many drawbacks: such as low thermal efficiency, energy waste, due to the high sulfur content coal, to atmospheric pollution. In recent years, the contradiction between supply and demand of energy and environmental pollution have become increasingly prominent. Compared with coal and gas, is one of the most clean fuel, he combustion, high thermal efficiency, low air pollution, good environmental performance.
First, to improve the fuel will be coal into gas in principle, more in line with the relevant environmental standards, coal as fuel for the szl series coal fired short construction period boilers has been subject to the authorities to stop, that there is often a company will be coal-fired boilers on the boiler rehabilitation programs into gas boiler embodiment, may use natural gas or alcohol as a fuel after passing through this transformation, the raw coal to reduce all kinds of pollution caused by the fuel, thus using not only environmentally friendly but also improvement in the fuel cost. Second, improve coal-fired furnace boiler furnace to transform into a blast furnace gas fired boiler is the use of auxiliary heating furnace, and then to improve the use of gas for heating, if not exactly when or poor fuel atomization in the combustion furnace gas gathering or tail, it is very prone to catch fire or explode, then the need for means to improve the furnace blast doors, while adding automation and control ignition and flame failure protection devices to ensure safe operation of the furnace process. Third, improve the pre-attached devices did not improve during the coal-fired furnace operation requires a lot of ancillary equipment to carry out normal operations, ancillary equipment commonly used in general including the coal, Cleaner, dust collector and grate and so on, after adoption of these boiler ancillary equipment gas furnaces do not need to use so that you can save and invest more of boiler equipment. Fourth, improve environmental protection degree We all know that coal-fired furnace has been impermissible environmental policy, coal is a serious source of pollution not only pollutes the environment but also cause a variety of effects on the body, after making use of the boiler gas furnace, greatly reducing soot and various soot emissions can effectively improve air quality, more environmentally better protect the cleanliness of the air, but also more in line with the standards of environment protection and energy policy.
