Solid particles, density, small size, easy storage, seal bags packaging, shipping convenient, clean and safe; fuel of high calorific value, high volatile, low moisture, is easy to ignite and burn and burn good results; low nitrogen content, oxygen content high and low temperature combustion, can reduce the generation of nitrogen oxides, CO2 can be achieved ecology "zero emissions", SO2, NOX than diesel desulfurization equipment is not used, the flue gas emissions can be fully met.
