Note the choice of industrial boilers from the first industrial revolution to develop microbial technology, and upgrading various products continue to emerge, led us to the development of human civilization from the original backward to technological civilization, to the boiler, for example, since the last century, there has been a cylinder since the boiler-shaped, with the needs of science and technology and production, from simple to complex, from single to serialization, boiler technology are developing rapidly, the good reputation of industrial boilers companies choose to share precautions industrial boilers; first, the coal use; the design of the cell structure based on coal boiler components as the design basis, select the boiler should pay attention to adjust to the type of coal in the region. It recommended new, high-efficiency, high-tech, high-quality, durable industrial boilers; second, parameter selection; industrial efficiency boiler work normally when approaching the highest efficiency rating, as the load decreases efficiency has declined. Boiler capacity is generally selected: it generates a large steam than the actual gas consumption, such as the required parameters and actual parameters difficult to match industrial boilers, high boilers in this case a gear selection parameter. Selection of auxiliary boiler should also refer to the above principles, to avoid the "big horse car"; third, the number of choices; normal maintenance of industrial boilers and boiler shutdown is a number of factors, but also pay attention to: the boiler room shall not exceed the number of boiler economizers work load, install boiler economizer device purpose is to avoid too much heat when the smoke away. Improve the thermal efficiency of the boiler, is provided in the back pass boiler economizer heating surfaces, the use of flue gas heating boiler feed water, to save energy, economizer after the installation, the boiler increases the thermal energy required for heating the feedwater, boiler water and so reducing the temperature difference between the water supply, reduce the burden of heating boiler feed water. Cause excessive number of boiler economizer can not play a role, resulting in waste of energy; These are high-quality industrial boiler company to share some notes selected industrial boilers; vast land of our country, many places are rich in coal, resulting in different types of coal , which has also become a basis for selection of parameters and select the number of boilers enable us to be more effective in energy conservation, to achieve a win-win.
To continue to improve ambient air quality, to meet the people's growing need for beautiful ecological environment, Zaozhuang City, Shandong Province issued the latest "blue sky Zaozhuang City win the Battle of the operational plan (2018-2020 years)" (the "Program"). "Plan" put forward, built-up urban areas to carry out experimental work, to carry out large-scale coal-fired units off white wet flue gas treatment. The main objective of the "program" is that after three years of efforts, the total emissions of major air pollutants significantly reduce greenhouse gas emissions reduction synergies, significantly reduced the concentration of PM2.5, significantly reduced the number of days of heavy pollution, ambient air quality improved significantly, the people of the blue sky well-being significantly enhanced. By 2020, the city of sulfur dioxide, nitrogen oxide emissions are lower than 27% in 2015, the ozone concentration significantly increasing trend containment; of PM2.5, PM10年平均浓度分别控制在 57 mg / m, 91 [mu] g / m or less, sulfur dioxide, nitrogen oxides average concentration continued to improve air quality not less than 62%, more than the number of days of severe contamination and declining.
