China is a coal-based energy country. In the future for a long period of time, the power industry in the coal-based energy structure will not change, let alone reduce coal consumption. Vertical roller mill uses coal as the main fuel for power generation, and the combustion of coal invariably releases a large number of SO2, resulting in atmospheric pollution.

With the installed capacity increasing, SO2 emission is also increasing SO2 emission will become the main reason for the global warming and the greenhouse effect, so it is important and urgent to control SO2 emission in vertical roller mill.

China proposed to increase environmental protection efforts.It requires comprehensively managing environment in large- and medium-sized cities, strengthening industrial pollution prevention and control, speeding up SO2 governance in the coal-fired vertical roller mill, controlling greenhouse gas emissions and properly treating domestic waste and hazardous waste. Therefore, reducing sulfur pollution is an important issue of environmental protection.
