A secondary desuperheater how to use the discount power plant boilers to start the process? Parameter Unit Method sliding pressure during startup, before the red switch turbine, the boiler side is generally not used to adjust the spray desuperheater steam temperature, but in the process when administered after a desuperheating water needs, to be arranged according to the characteristics of the desuperheater parameters and characteristics under different conditions, the rational use of a secondary desuperheater, so not only ensure the safety of the superheater, but also ensure that the main steam temperature rises steadily.
Harbin Ecological Environment Agency announced plans to complete this year, Harbin more than 65 tons of steam coal-fired discount power plant boilers soot ultra-low emissions and transform 140 units, ultra-low emissions of sulfur dioxide coordination to complete the transformation of 51 units, ultra-low emissions of nitrogen oxide transformation 20. Currently, the transformation plan has been, is being gradually start building renovation project.
Harbin nine districts built-up area and more than 65 tons of steam coal-fired boilers totaling 156 units, according to the national, provincial requirements, before the end of 2020 to complete the transformation of ultra-low emission. By the end of 2018, it has completed the transformation of ultra-low emissions to 16, and the remaining 140 units planned to complete the 2020 pre-season heating. This year's program priorities ultra-low emissions of soot complete transformation of 140 units, ultra-low emissions of sulfur dioxide coordination to complete the transformation of 51 units, ultra-low emissions of nitrogen oxide transformation 20; completed 2020 pre-season heating boilers remaining sulfur dioxide, nitrogen oxide pollutants over low-emission transformation. Up to now, the district had been held property unit boiler promotion meeting, 28 companies have 140 boiler by one to clear a specific time frame for completion and responsible persons, are gradually start building renovation project, planned before the end of September to complete the transformation of building construction; the end of October front, complete run debugging; before the end of December to complete the project acceptance.
It is understood, Harbin source of ambient air particulate matter analysis result display, the largest contribution to the PM10 and PM2.5 pollution sources are fired, share ratio of 31% and 36%, respectively. Ultra-low emissions of coal-fired boilers is mainly transformation soot particulate matter reducing emissions to the atmosphere, thereby reducing the concentration PM2.5, effectively improve air quality.
How important gas steam discount power plant boilers air consumption is calculated with the arrival of cold winter, gas steam boilers used for heating has become the main force in the market for gas steam boilers enterprises, boiler air consumption is a measure of the energy efficiency of a boiler ? indicators, then the gas steam boiler air consumption how it is calculated as a gas steam boiler pot Zheng http://www.zgrongqi.com/ well-known companies, analyzed the calculation method of heating gas consumption for the following effect gas steam boiler: 1, the first heating season the highest consumption of gas, and then decline every year, a few days before the first gas consumption maximum heating season, and thereafter gradually reduce, three weeks later will reach a more stable air consumption. 2, the second heating season than in the first heating season, day reduce air consumption by about 30%. 3, the top layer and the intermediate layer of a relatively gas consumption plurality day about 15%. 4, the same layer with the male side nightside day room air consumption of about 10% difference. 5, when the surrounding neighborhood is not heating, gas consumption will increase by about 40%. 6, if the user or night when no one is lowered to room temperature 15 ℃, the cost can be reduced by about 45%.
In the construction of the boiler room, according to the weight and size of the design of electric steam boilers, you must allow sufficient space for boiler use.
