The paper describes the fuel compositions of coal-water pastes (CWP) for PFBC boilers or furnaces, which comprise a first solid combustible having a CSN (crucible swelling number) of 0 or 112, a second solid combustible having a CSN of > 1, and liquids. The solid combustibles include coal, coke, petroleum coke, char, city refuse, and industrial wastes. The CWP fuels improve the inhibition of freeboard-zone combustion of the PFBC boilers.
