Get Price2018-10-20u2002·u20024.1. Heating Value or Calorific Value. The calorific value of refuse (fuel) is a complex function of the elemental composition of the refuse. It is a property of fundamental importance. Test values are obtained by burning a 1g or 2g samples in oxygen at 25 MPa pressure in a bomb calorimeter (ASTM standard D 2015-73).
Get Price2021-11-18u2002·u2002It makes use of rotary drum drying process to effectively reduce sulpur and ash content ofcoal after four-level low temperature drying process while ensuring quality of coal to be dried remains unchanged. Moisture content of coal material is reduced to less than 12% so that to reduce transportation cost and increase calorific value of lignite.
Get PriceOur lignite dryer can reduce the moisture content of lignite 25-60% to 15-30%, and the calorific value of treated coal can be increased by 30-40%. It is directly used as a substitute for bituminous coal or anthracite power plant use.
Get Price2021-12-17u2002·u2002Coal seam pores are the major places for coalbed methane storage, diffusion, and seepage, and changes in the pore structure cause changes in the porosity. The porosity of coal seams can be effectively improved by applying strongly corrosive and oxidative chemical reagents to coal seam pores, but these reagents may pose threats to coal workers, corrode mining …
