For a long time, the development of our electricity sector has been dominated by fire and electricity. Clean energy sources, such as wind, nuclear, hydropower and photovoltaic, have gradually emerged as a result of technological developments, but for the time being, fire and electricity still dominate our electricity system. With increasing environmental requirements, the major pollution disadvantages are becoming more apparent, and the prevention and control of pollution from power plants has become the focus of current environmental efforts, and the State has put in place a series of documents, measures and incentive policies to support the implementation of very low-emission rehabilitation of power plants. The Zhedilong is dependent on years of technical reserves and practical experience in the field of monitoring to provide gas and particulates monitoring and operational maintenance solutions for power plants, such as fuel storage, flue gas purification and extremely low emissions, based on the characteristics of the fire and power industry.
