The heating project of 70MW high efficiency and low exhaust pulverized coal boiler of a heating company in Jining, which was contracted by our company, was put into operation in the heating season of 2020.This is our company in 2020 following the Feicheng Tai'an 58 mw high-efficiency low-emission pulverized coal boiler put into operation after another set of formal operation of large-scale heating projects.The stable operation of the boiler above 95% load effectively alleviates the heating pressure in the local urban area, and contributes to the strength of Huayuan to protect people's livelihood in the warm winter.

The boiler type of this project is DHS70-1.6/130/70-A III, the design thermal efficiency is more than 90% , the coal burning rate is more than 98% , which is in line with the current national policy trend of clean and efficient utilization of coal.After flue gas treatment measures such as dust removal, desulfurization and denitrification, the emission of pollutants can be controlled to the ultra-low emission standards of dust ≤5mg/Nm3, sulfur dioxide ≤35mg/Nm3 and nitrogen oxide ≤50mg/Nm3, meet the 2 + 26 beijing-tianjin-hebei air pollution transmission channel city's strict environmental requirements.
