Clean coal power system
Patent
·
OSTI ID:6218322
A coal burning power plant which produces electricity at high efficiency and with very low levels of atmospheric contamination. A fluidized bed of limestone and coal is used to burn the coal with little air pollution, and a large quantity of specially constructed heat pipes transfer the heat to a closed cycle gas turbine with very low temperature loss. The preferred embodiments of the heat pipes are constructed with steel casing, have a thin aluminum oxide layer on their surfaces to prevent hydrogen permeation into the casing and have a plasma sprayed coating of ceramic on the portion within the fluidized bed to prevent erosion of the heat pipe casing by the solid particles within the bed.
