Local governments have taken measures to curb the situation, including the well-noted and widespread scope coal-to-gas project. Natural gas, as green energy, is encourage to take the place of coal. More than that, NOx emission is under stringent control, which is believed to be a significant factor contributing to dense haze.

The Low NOx combi boiler D1 series developed by our company, with innovative design, including low fire burner, variable speed fan plus corresponding control system, renders NOx emission far under the national standard, less than 30mg/kw.h. This makes our product very popular with local government and drives sales of our products in the area.
