vertical shell fired tube boiler

Recently, Chuzhou City, Anhui Province issued a "Chuzhou Municipal People's Government on the issuance of Chuzhou City to win the Battle of the sky three-year action plan to implement the program," which raised more for coal-fired governance requirements, as follows.

First, the continued implementation of the total coal consumption control. As of 2020, the city's coal accounts for a further decline in the proportion of total energy consumption; the city's coal consumption to complete the tasks assigned by the provincial government; a new coal project implementation reduction of coal instead.

Second, the implementation of the "coal to gas" and "electricity instead of coal." Under the premise of the implementation of the gas source, protect people's livelihood, glass, foundry industry to actively promote natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry energy characteristics, and actively promote the residential electricity, industrial production, building heating heating, transportation, production of five major areas of agricultural implement "electricity instead of coal", focus on improving the proportion of final energy consumption of electricity accounted for.

Third, carry out comprehensive improvement of the boiler. Increase efforts to eliminate small coal-fired boilers, to consolidate the results of coal-fired boilers eliminated. The city basically eliminated 35 tons of steam per hour of coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities, no new 35 tons of steam per hour of coal-fired boilers; 35 tons of steam per hour more coal-fired boilers (excluding boiler coal-fired plants) all meet the special emission limit requirements; 65 tons of steam per hour and above all coal-fired boilers and energy-efficient ultra-low emissions to complete the transformation. Low-nitrogen gas boiler substantially complete transformation; urban built-up area of ​​ultra-low emission biomass boilers implement reform.

Fourth, increase the technological transformation efforts cogeneration units to speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network coverage and bulk coal fired boilers within range. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume.

Fifth, strengthen the bulk coal governance. Full implementation of the "Interim Measures for commercial coal quality management" and coal-fired boiler technology standard, good bulk coal use Survey, the development of bulk coal governance implementation. Expand the scope of urban high-pollution fuel combustion zone ban, and gradually extended to the outskirts of the urban area. Combustion zone ban prohibiting the use of high-polluting coal for fuel, the progressive realization of no coal rank. Daly promote quality and new coal stoves, improving combustion efficiency.

Pre-purchase preparation and steam vertical shell fired tube boiler steam pressure regulating steam boiler, which is a common and popular types of boilers, but also one of the website product, so it is necessary to be familiar with and understand, because it can achieve product and reasonable use make full use of these two purposes. And based on the specific requirements are set forth below and explain its content-related knowledge, to explain its specific as follows. 1. Are there preparatory work before steam boilers to buy? Is it important? Steam boiler products before making the purchase, is the need to do some preparatory work, but also to pay attention to this work and to take seriously and carry out, because if the problem affects the right to buy products, so can not be ignored and careless treatment. On the job content, one has to use the environment and product requirements clearly understood, the second is to understand the product and the manufacturer some basic information, including product origin, specifications, size, performance and technical parameters, product quality and price and product service, good conduct multi-comparison and taking into overall consideration, so they have accurate judgments and the correct choice. 2. Why steam boiler filled with water to avoid the phenomenon? Steam boiler in the course filled with water to avoid the phenomenon, because once this phenomenon, will bring a lot of water vapor, and steam pipes may cause the boiler water hammer phenomenon occurs, and thus, reduce the quality of steam and affecting the normal for the steam boiler. If the comparison the worst case, can lead to damage to the superheater and steam equipment fouling. Therefore, based on these adverse effects, this will have specific requirements. 3. sub-cylinder steam boiler is not special equipment? Its parameters are the same as hot water boiler? Steam boiler sub-cylinder, from a professional point of view, belongs to special equipment, and is part of a pressure vessel, so when the boiler installation to installation supervision and inspection together with the boiler, can not be omitted and ignored. Parameters of the steam boiler, which is a capacity of the boiler, the steam temperature, steam pressure, and these parameters, so it is compared with the hot water boiler parameters, are both the same parameters have different parameters. 4. Steam boiler steam pressure how to adjust? Desired steam pressure of the steam boiler is adjusted by varying the amount of fuel can be one to achieve the object, the amount of fuel, the boiler heat absorption will increase, thereby increasing the production of steam, the steam pressure increases, and vice versa is decreased; Second, by changing the steam valve opening degree greatly object, a large pressure reduction valve opening, the valve off a small pressure increase.

4, explosion caused by severe overpressure;

5, due to the failure of safety accessories, structural design is not fair, material decay and other reasons, resulting in boiler explosion.
