Fluidized bed boilers use the principle of burning fuels in a fluidized bed. A fluidized bed creates conditions suitable for the uniform combustion of fuel throughout its volume, which means, as a final result, more perfect fuel burn-up (high efficiency of a fluidized bed boiler) at lower combustion temperatures and whilst reducing the production of harmful waste gases at the same time.
4 tons of heating boilers present price how much heating boilers mainly to use hot water. So now a lot of pressure hot water boiler heating boilers are generally as large tonnage of heating boilers are local heating enterprises used. Therefore, the heating unit for the procurement of boilers is more cautious. That, after all, belong to the expenditure of government finances. Therefore, many of the companies in the procurement of heating boilers must go through many aspects of comparison. Recently, there is a fast boiler heating companies to consult, he is a local heating companies, primarily responsible for the district heating. Want to purchase a heating boiler, but for specific models and prices not very understanding. Fast boiler technician for detailed information of the company after understanding the accounting data to show that the company with a 4 tons to meet the heating boiler is, the current price of this model is about 500 000 . In this regard, the company's procurement staff for the price of 4 tons of heating boilers already have a general understanding.
To prevent air pollution and ecological damage, protect and improve the environment, promote the construction of ecological civilization, and promote sustainable economic and social development, Nanjing, Jiangsu Province to develop and launch the "Nanjing Atmospheric Pollution Prevention Act," played on May 1, 2019 official implementation.
1, the implementation of energy consumption and total coal consumption control and intensity control system. City of total energy consumption and coal consumption control administrative department with the relevant departments in accordance with provincial and municipal energy conservation requirements, the preparation of periodic control energy consumption and total coal consumption embodiment, the Municipal People's Government for approval.
2, high-pollution fuel combustion zone ban prohibits the sale, burning polluting fuels; prohibit new or expanded high-polluting fuel burning facilities; has been completed, should stop using within the prescribed period the Municipal People's Government, or switching to natural gas , liquefied petroleum gas, electricity and other clean energy.
4, petrochemical enterprises should strengthen the recovery of combustible gases. Flaring device should be used to deal with emergencies, not as a daily air pollution treatment facilities.
5, to encourage the production, use, or free of volatile organic compounds less volatile organic content of the feedstock and products. Surface coating, packaging, printing, furniture manufacturing and other industries should use low VOC content of products. Petrochemical and other organic solvent, the company should improve the production process, a low content of volatile organic materials and products.
6, resulting in production and business activities of volatile organic waste gas should be carried out in a confined space or equipment, and the installation of, use of pollution control facilities. Shipbuilding and other production and business activities can not be carried out in a confined space, and building (structure) building routine maintenance of live animals, roads, bridges, etc., should take effective measures to reduce emissions of volatile organic compounds.
The cross section of boiler hearth is generally square or rectangular. Fuel burns in the furnace to form flame and high-temperature flue gas, so the furnace wall around the furnace is composed of high-temperature resistant material and thermal insulation material. Water-cooled wall tubes are often installed on the inner surface of the furnace wall, which not only protects the furnace wall from burnout, but also absorbs a large amount of radiation heat from flame and high temperature flue gas.
