What types of auxiliary boilers analysiss are currently furnace use? Furnace is a boiler shell type specific pressure member. Internal combustion furnace is, outside the boiler water, under external pressure. Therefore, it is the worst working conditions the pressure receiving member in the boiler shell type, one of the most easily damaged component. Due to the high temperature furnace combustion flame, which is higher than the temperature of the boiler shell, its thermal expansion problems in particular. Especially oil-fired boiler, the combustion temperature due to the high oil, high furnace thermal strength, severe temperature changes, it requires the furnace to have a good thermal expansion properties. Currently there are in the form of a flat furnace of cylindrical shape, with a straight cylindrical reinforcing ring, corrugated and the like.
Traditional coal-fired auxiliary boilers analysiss inefficient and highly polluting; high fuel boiler operating costs, but also by pipeline constraints, the cost is too high; gas-fired boiler using natural gas as a clean fuel, soot content itself has very little, or even negligible, excellent environmental performance, loved and recognized by many enterprises and government departments.
Heilongjiang provincial government to respond positively to win the Battle of Blue Sky policy action plan issued by the Ministry of ecology and environmental protection, recently issued "on the issuance of Heilongjiang Province to win the Battle of the sky three-year action plan" (hereinafter referred to as "Plan").
"Plan" requirements, as of 2020, the province of sulfur dioxide, nitrogen oxide emissions are decreased year on year in 2015 to more than 11%; PM2.5 did not meet the concentration level and above cities fell year on year in 2015 to more than 15% , and above the level of urban air quality days ratio reaches 88%, and more heavily polluted year 2015 the number of days decreased the ratio of 15% or more.
"Plan" put forward 47 specific measures from nine aspects, namely: to adjust and optimize the industrial structure, promote the formation of green development; speed up the adjustment of energy structure, build clean energy systems; actively adjust the transport structure, the development of green transportation system; optimal adjustment of land structure, promote urban and rural non-point source pollution control; strengthening regional joint prevention and control, to effectively deal with heavy pollution weather; sound regulations and standards, improve environmental economic policies; for strengthening the infrastructure, strict environmental enforcement inspectors; clear responsibility for implementation of the parties, strict accountability assessment ; strengthen information disclosure, mobilize the whole society to participate.
"Plan" requirements, strictly control the total coal consumption.
1, in accordance with the focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, coal and oil to promote alternative energy by 2020, cities (prefectures) Coal accounts for the proportion of energy consumption fell by 1.5% compared with 2015.
2, bulk coal strengthening control, adjustment and optimization of high-pollution fuel combustion zone ban, the use of high-pollution fuel control, bulk coal alternative strengthening. Clean steadily heating, promoting the use of clean coal and clean energy.
3, to carry out comprehensive improvement of coal-fired boilers, to carry out level and above urban area 10 steam tons / hour coal-fired boilers and "clear" action. Improve energy efficiency, we continue to implement the dual-control operations total energy consumption and intensity.
4, accelerate the development of clean energy, and orderly development of wind power, biomass power generation and actively promote the construction of hydropower development focus on the promotion of river basins, and strengthen the development and utilization of geothermal energy exploration, increase renewable energy consumptive efforts.
Gas-fired power plants are an important part of China's power industry. The use of water in the power industry is multi-faceted, including auxiliary boilers analysis replenishment, cooling water, and miscellaneous water for life. The most stringent water quality requirements are boiler replenishment water. Nowadays, thermal power plants are developing towards large capacity and high parameters. The water quality of boiler water is also getting higher and higher. The boiler water quality requirements are very strict, not only requiring low hardness, dissolved oxygen. Very small, solid content and organic content are also very small, water that does not meet the water supply standard will make power plant equipment unable to operate safely and economically, so in addition to conventional coagulation, sedimentation, filtration and other water treatment methods, ion exchange is required. , complex bed, mixed bed, reverse osmosis desalination treatment system, electrodialysis and other softening, desalination high purity water system, ultrapure water treatment equipment technology to treat super high pressure boiler feed water in thermal power plants. To this end, quality indicators for various water uses in thermal power plants have been developed.
