In recent years, around the air pollution is more and more attention, biomass pellet machine market boomed accordingly, in this year, kunming more scientific and effective, practical and feasible measures for the control of air pollution, issued "about in the city's use of biomass solid formed fuel supplement notice, guiding the biomass solid fuel use, urged guidance related units outstanding high pollution in fuel to burn main biomass fuels (recommended), revamping work finished enterprise of coal-fired boiler, urged relevant enterprises to stop using coal-fired boiler.

Kunming city environmental protection bureau jointly city live built bureau, the city urban management bureau issued "on further strengthening the construction site dust control work notice, together to promote the urban construction site dust pollution control work.

As of June 15, 2014, the city of kunming has completed 635 units (sets) of boiler, furnace and more than twenty thousand eye geo-thermal, hot stove, ChaShuiLu, small coal change, reconstruction work, to ban the production, sale, the coal enterprises, self-employed, 1800. Air quality warning notice 64, the main environmental air quality monitoring 166 days, the optimal class number 28 days, 128 days, good light pollution for 10 days, air quality success rate was 93.94%.

Anyhow, biomass fuel comprehensive promotion at the same time also led to the development of biomass granule machine, only in this way, people's living environment can be improved.
