To further promote the comprehensive management of coal-fired boilers, Jincheng City, Shanxi Province, according to "Jincheng Blue win the Battle of three-year action plan" requirements, plans to complete 109 units of 10-20 tons of steam "small coal-fired boilers" within this year the phase-out, at the same time, Jincheng will start working out of 35 tons of steam coal-fired boilers.

This year, Jincheng counties (cities, districts) the environmental sector will urge the relevant enterprises and institutions to eliminate the basis of 10 tons of steam and coal-fired boilers on in 2018 to accelerate the phase-out and 20 tons of steam coal-fired boilers. This year, the city to complete 109 units (10-20 tons of steam boilers) working out of a total of 589.5 tons of steam boilers; at the same time, Jincheng will also speed up the foundation and 20 tons of steam coal-fired boiler out, start 35 tons of steam phase out coal-fired boilers, in principle, within the city's new domain-wide 35 tons of steam coal-fired boilers.

In addition, Jincheng will accelerate the transformation of ultra-low emission. Before the end of September this year, the city will complete 52 units (65 tons of steam per hour and higher coal-fired boilers) coal-fired heating boilers ultra-low total of 4530 tons of steam boilers transformation, and the county (city) built-up area, biomass boilers emissions transformation. After transformation, under condition of the reference oxygen content of 6%, soot, sulfur dioxide, nitrogen oxides emission concentration of these boilers respectively not higher than 10 mg / m, 35 mg / m and 50 mg / m.

Transformation of low nitrogen in the combustion aspect, before the end of October, Jincheng station 610 will complete the transformation of low-nitrogen combustion Total 1940.15 tons of steam gas boiler, after completion of the transformation, the boiler NOx emission will not exceed 50 mg / m.

Heating boiler auxiliary equipment and piping installation requirements What? Heating boilers in which the mounting auxiliary equipment and pipe specifications, and there are some specified requirements. Therefore, the following specifically explain, elaborate knowledge of the content it contains, which allow us to clearly understand that in order to have a firm grasp, and be applied flexibly. Heating boiler, the mounting regulate their auxiliary equipment and piping, it is mainly: (1) for the auxiliary equipment based on the strength of the concrete, is necessary to meet the design requirements, so that it can be securely mounted boiler. In addition, the foundation coordinates, elevation, location and geometry of the bolt holes, etc., but also meet the requirements, so as to. (2) The open boxes, cans and the like, to be installed before the full water test, which is generally filled with water, and allowed to stand for 24 hours to check for leaks or leakage problems, yes, then the test is not by. In addition, the hydrostatic test should be carried out, time is 10min.

Now residential areas generally take energy-saving measures, heating and heat index selection 45W / m, single 5.6MW boiler meet the heating area of ​​about 80,000 square meters.

Present during food factory boiler shutdown problems and the presence of food plants during the cause of corrosion problems and corrosion of boiler shutdown reasons. In the detection process of industrial boilers, we found a large boiler within a year than their long working hours, but the boiler corrosion and maintenance during the shutdown has not taken seriously enough. Boiler maintenance is directly related to the life of the boiler. 1, there is the food plant boiler shutdown problems during the inspection process, often see a number of small workshops, small business operation is not standard, boiler boiler stops during maintenance work is not in place. Vertical pipes fixed furnace LSG0.2-0.4-AII on September 12, 2015 put into operation. Semi-open boiler room, there are three annular wall. Is unshielded side, top covered with the boiler steel tile color, but some damage. Stop the stove without any treatment until the check fugitive emissions so far. Test found the following problems: ① the heat insulation breakage outer layer, local corrosion 0.5mm.
