Coal – Global Energy Review 2020 – Analysis

We expect global coal demand to fall by about 8% in 2020, the largest drop since World War II, with coal use declining in virtually every sector of every region in the world. In China, coal demand will decline in 2020 by around 5%, despite the gradual recovery since February lockdown. Coal-fired power generation will be hit especially hard, because the power system is crowded by …U.S. Energy Flow - Energy Information AdministrationU.S. Energy Information Administration 1000 Independence Ave., SW Washington, DC 20585.

The final void fraction of the coal powder beds is the porosity of particle bed when the voids of coal particle bed are filled with water. Void fraction of CWS was calculated by the following equation (Henterson, et.al, 1978).
