water tube boiler repaires

Electric heating hot water water tube boiler repaires Products: electric heating hot water boiler consists of furnace, electronic control box and a control system. Electric heating boilers as a new type of boiler equipment, environmentally friendly, clean, no pollution, no noise, automation, etc., with the sharp rise in prices of energy and reduction, more attention has been paid. Electric heating tube is the core component of the electric heating boiler, which directly determines the life of the boiler. Chosen as non-metallic electrical heating tube (such as a ceramic heating pipe), because it has a load resistance, long service life, the hydraulic separation structure, and the boiler does not leak.

Water pressure test must be carried out before operation of oil-gas water tube boiler repaires

Whether it is a steam boiler or a hot water boiler, after the boiler is installed, a hydrostatic test (ie, water pressure) must be performed. Because of long-distance handling, loading and unloading, installation, it is inevitable that collision and damage, through the water pressure test can find the boiler defects and take appropriate measures in time to ensure the boiler operation safety. The following is an example of a fuel gas boiler water pressure test:

After years of efforts, the overall governance of Beijing's total coal consumption has achieved initial results. By the end of 2017, all of the total coal consumption of 4.85 million tons, accounting for only 5.6% of the city's total coal consumption, coal-fired completed three years ahead of "Thirteen Five" energy development plan period proposed control in less than five million tons The goal.

By 2013 to 2017 for five consecutive years to promote the work Yajian coal, Beijing successfully completed the first phase of the "Yajian based" Yajian coal work, go to "run mainly to protect", established clean energy use long-term mechanism to combat second phase coal-fired rebound. Beijing's total coal consumption in the future will be long-term control in less than 4.2 million tons, coal is mainly used for urban hazardous waste incineration, energy and protect the city safe operation of remote mountain villages Beijing winter heating three aspects.

As of last heating season, heating central heating proportion of clean energy in Beijing has reached 98%, in addition to parts of Pinggu and Yanqing, Miyun three zones as well as six coal-fired heating boiler room, other regions have achieved heating boilers no Coal.

This year, Beijing will complete the rural village 450 villages, the villagers coal public spaces and 53,000 square meters of agricultural facilities Zizhong change clean energy work, and strive to complete the Yanqing east of central heating central heating fuel in pre-season coal boiler clean energy transformation, in an orderly coal-fired heating center south of Yanqing, Pinggu Riverside, Xinggu, Miyun Taishi Tuen urban and non-built-up areas boiler clean energy transformation.

In addition, this year, Beijing Yanshan Petrochemical Industries will start coal-fired facilities clean energy transformation, and continue to consolidate six districts of the city, the southern plains "No Coal" results have been achieved on the area of ​​clean energy transformation, embargo, ban, ban save bulk coal, to prevent rebound.

Speed ​​up the construction of clean energy facilities, Beijing will work to enhance the rural town of Plains gas pipeline network construction, improve rural consumption of clean energy supply security capacity, promote Plains natural gas pipeline "through town." In the gas network facilities are relatively weak areas, speed up the liquefied natural gas, compressed natural gas supply facilities, increase the supply capacity of natural gas distribution in rural areas. At the same time, we continue to promote the 2018 "from coal to gas," "coal to electricity" supporting gas engineering and construction of power transmission project, to meet the full 2018-- coal to clean energy by 2019 energy demand for the heating season.

When the external load variation, the temperature in the water tube boiler repaires and metal working fluid, the heat and other changes have occurred. When the load increases as combustion is not timely adjusted so that the steam pressure drops, the corresponding saturation temperature drops, a corresponding reduction in boiler water liquid heat, and the heat storage pot of water at this time in the metal release, will become part of vaporized boiler water itself steam. These generate additional evaporation, can play a role in mitigation of the vapor pressure decreased.
