Our enviromental pellet stove has been granted Innovation Excellent Award from Shell Foundation in 2007 for High Efficiency, Low Emissions Household Biomass Stoves In China And Abroad. This is achieved by burning the fuel using a controlled supply of air that produces gas which then rises to meet ' secondary' air causing the fuel to burn more thoroughly. This ensures that the fuel burns more efficiently and that heat is transferred to the pots more quickly which allows a meal to be cooked in around 15 minutes with minimal smoke pollution.
