Korea Southern Power (KOSPO) is in the process of building a thermal power plant that is designed with carbon emissions reduction in mind.The Green Power Project will employ low grade coal fuel and super critical CFB (circulating fluidised bed) boilers.ZG boiler has won a contract to design,supply and build a 35 MWe coal fired circulating fluidised-bed (CFB) power plant boiler island that will be part fuelled by demolition waste.
Rinsing step boiler water level gauge for boiler water level gauge flushing clean water level gauge mica or glass, to prevent clogging of the steam or water communicating tube, to prevent erroneous determination caused by operating personnel accident level. The step of rinsing water level gauge as follows: (l) soft drinks first side of the secondary door is closed, to open 1/4 ~ 1/3 times, and then open the door turn on the water, and washing soda mica conduit. (2) stripping off water measured secondary-side doors and mica flushing conduit. (3) off the water of the secondary side of the door, the second door ajar steam side, the steam side and the mica sheet for rinsing. (4) micro-water side of the secondary door, turn on the water shut the door, the water level should rise quickly, and fluctuates slightly, indicating clear, or should be washed once again. (5) The secondary side soda doors open, and the other with control water level gauge, indicating consistent. (6) should not be too long time rinsing water level gauge, and the protection level gauge pin to prevent clogging.
Note that, these condensing boiler cleaning errors occur frequently in many condensing boilers manufacture, transport and installation in a variety of situations will occur, so that the pipe wall boilers accumulate a large amount of dirt or other impurities in the oxide, resulting in the initial boiler run directly heating surface corrosion damage. To this end, boiler manufacturing companies will configure a set of operating instructions for each condensing boilers, including cleaning this one. Then the process consumers condensing boiler cleaning in which errors can strayed, how to avoid it? A chemical cleaning process does not detect the chemical analysis is a very rigorous chemical cleaning process. But if chemical cleaning is not complete, some dirt is not completely clean; and if the cleaning time is too long, there will be over-wash phenomenon; good cleaning effect, a secondary cleaning will waste of raw materials, and waste time. Which will increase the erosion had washed condensing boiler, condensing boilers metal pressure caused by a reduced ability of the normal operation of condensing boilers after impact. Improvements are: chemical analysis must be prepared to detect chemical cleaning processes, test once every tens of minutes acidity, total iron ion concentration, PH value. When two close data laboratory analysis, chemical cleaning end point is reached, and be discharged after reaching the neutral acid. Second, chemical cleaning is not performed after completion of the passivation process is the process of passivating the clean surface of the condensing boiler deactivators re reaction. Since the control point passivated more stringent requirements, if not properly controlled, the passivation will fail, and if the pickling is completed, and only a simple cleaning is finished, which makes the surface to be cleaned boiler condensate prone to two secondary rust, scale condensing boiler capacity decreases, prone to rust improvements: condensing boiler after pickling, passivation must be rinsed, since the passivation more stringent requirements, thus rinsing process must be strictly controlled total iron ions concentration. After rinsing is complete, iron ions tested meet the requirements, the PH value immediately adjusted to strongly basic, and the passivating agent is added, warmed passivation. It can be learned from the above, chemical cleaning condensing boiler there are more abnormal phenomena, and that the life of the condensing boiler, safe operation, energy production had a negative impact, therefore, in order to eliminate these abnormal phenomena, sustainable development and safe use of condensing boilers environment has a very big role.
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.
