Abstract
A method and apparatus for heating fluids, such as an agglomerating slurry of coal and water, to supercritical conditions, wherein an electrical current is passed directly through the fluid. The fluid is directed through a container and heated by passing an electric current between a conductor positioned within the container and the interior surface of the container. The current passes through the fluid, and the electrical resistance of the fluid dissipates the electrical current into heat energy, resulting in the direct heating of the fluid. The rate of heating is preferably controlled by adding an electrolyte to the fluid.
