In recent years, the country frequent st petersburg russia boilers company explosion hurts. In order to boiler explosion hazard within the city limits of strangled in the cradle, Tongxiang City, Zhejiang Province Environmental Protection Bureau began efforts to expand the investigation and remediation action on the bathroom boiler.
To strictly implement the ban on burning district requirements, to further improve the quality of urban environment, improve ecological satisfaction, since mid-February this year, Tongxiang City, four environmental protection will be co-related units Indus streets, to carry out this major investigation large heating boilers campaigns, decided to launch a big investigation on urban use hot water bath, foot bath shops, hotels and other business, the use of high-polluting fuel combustion zone ban on large renovation of heating boilers, continuous efforts to fight the "battle of the sky" .
According to preliminary statistics, the use of hot water units to provide services related to nearly 100 within the city limits, as of now, the investigation related to environmental protection has four units of 65, found that the use of biomass boilers 6 sets, 1 small coal-fired boiler units, diesel 1 small boiler units.
According to the investigation objectives edge side of remediation, environmental protection and the use of four pairs of high-polluting fuel boilers Daihatsu small bathroom has been ordered to stop using it immediately; the use of biomass boilers units of gold Water Cube, has been ordered to make corrections, use clean energy heating or hot water outsourced way.
"After a major renovation a few years ago, the small coal-fired boilers have been basically eliminated banned, but there are still dynamic changes and new heating boilers. Next, we will continue to carry out large investigation heating boilers, within city limits investigation and implementation of full coverage, and we will also carry out rectification 'look back', initially planned to be completed this major investigation big campaigns before the end of April. "Zhu Yaming, director of environmental protection four said Tongxiang three cadres of the Conference" seven action "mobilization meeting sounded the full implementation of" urban quality improvement action "horn, as" beautiful Tongxiang "vanguard construction, environmental protection and ecological environment people will be" two upgrade two down "as the goal, create beautiful ecological upgrade urban quality, Tongxiang boost economic and social development of high quality, is to make people's lives better and make unremitting efforts.
How many stages does the st petersburg russia boilers company ignite? Boiler ignition, from a professional point of view, is for heating, combustion and transition to normal combustion three stages. The heating is that the material layer is heated to a certain temperature in order to carry on the work of combustion and so on. For all of us, we should know the three stages of boiler ignition, so that the boiler ignition can be carried out smoothly.
Pressure st petersburg russia boilers company is designed such that: if pressure boiler manufacturers introduced low nitrogen how to improve the quality and service life of boiler: 1, planning to improve the quality of low nitrogen boiler pressure boiler to improve the quality of planning from the structure, thermal design progress boiler pressure boiler shrink expansion margin; 2, key parts of the structure can be supplied from the selection of the double-sided welding conditions, the welding improve the quality of the boiler; improving tobacco cell structure, reducing boiler cleaning boiler fouling or convenient, long-term internal cleaning boiler and transfer of heat; 3, optimization of the boiler structural reinforcement repairable boiler, and easy maintenance of the service life, the progress of the boiler; 4, when planning a low nitrogen boiler shell, enhancing the rigidity of the boiler body to avoid deformation of the housing in use, the long-term maintain the appearance quality of the boiler.
Residential homes use low nitrogen hot water st petersburg russia boilers company hot water boiler is running low nitrogen points in many residential homes have been widely used, mainly used for winter heating demand and supply of hot water. He joined the low nitrogen technology hot water boiler flue gas cooler and fewer harmful substances to people's living environment and health to provide a guarantee. However, in order to further ensure its safe operation, when the residential area of low nitrogen hot water boiler operation the following points should be observed. A, water temperature and to control the speed of cell Sheung residential low-nitrogen starts to operate when the hot water boiler, the boiler and the temperature of each component is ambient temperature and the same will be with the combustion boiler, the temperature began to rise; but because the relatively thick wall of the boiler, so that the outside temperature rises more slowly, resulting in a temperature difference generated inside and outside wall. Nitrogen and low boiler manufacturers find the temperature difference between the inside and outside will be greater as the thickness, if the water temperature is likely to rise through the interior of the boiler will be deformed cracks are formed. Nitrogen is low boiler manufacturers emphasize To avoid this situation, one should control the Sheung speed and the water temperature, so as to be uniform so that the temperature rise in the inner and outer walls of the boiler, in order to protect the boiler is not destroyed. Second, to control the rate of temperature rise in a low nitrogen starting water boiler combustion process, as the temperature rises inside the pressure will rise, so the two are performed simultaneously, and the pressure was gradually elevated process , not only the inner and outer walls of the thick drum will produce a temperature difference, and also other parts of the thermal stress is generated due to this change, which is detrimental to the maintenance of low nitrogen hot water boiler, so professional hot water boiler manufacturers of low-nitrogen - fast boiler remind you, we must control the thermal stress and reduce as much as possible in order to avoid excessive heating adversely affect the important parts of the pipeline pressure, flow plates and so on. Third, the boosting speed should be adjusted during the low nitrogen pressure inside the boiler rises, the need to go through several different stages, and the pressure is increased by a certain entity, the increase rate is not the same saturation temperature of the working fluid, and the lower the pressure, increased at a rate corresponding saturation temperature rise and greater unit pressure as the pressure increased, increase in the saturation temperature of the water will become increasingly smaller. Therefore, the national professional boiler manufacturers introduced low-nitrogen booster is very slow at the beginning of time, but wait until the situation under relatively high pressure can be suitably adjusted to improve the speed boost, because elevated pressure and elevated temperature has influence each other , it is not possible to separate transfers, must be considered to operate. These are the residential district of low-nitrogen process hot water boiler operation is important to note three aspects, in addition, individual components will occur due to heat expansion and elongation of the boiler in the heating process, it is necessary to do the protections. For example, you can take certain measures and monitoring temperature control of work in order to be able to ensure their expansion in the normal range, while specializing in the production of low nitrogen boiler manufacturer reminder to take some measures to make the two internal boiler temperature control the speed but also to maintain a uniform temperature distribution to be able to protect the equipment.
