ABSTRACT:
A process for producing a coal-water mixture includes classifying a coal feedstock to form first and second coal feed streams each comprised of differently-classified coal particles. Separate surge vessels receive the coal particles to form separate feed streams. The distribution of coal particles in a liquid medium forming each coal feed stream is determined and an electrical signal is delivered to the microprocessor for controlling the portions of each stream which are mixed together in the presence of a dispersing agent and a stabilizing agent to form a coal-water mixture. The coal-water mixture is comprised of at least 65% by weight coal particles and this may be increased to about 82% by controlling the distribution of coal particles in the liquid medium forming each of the coal feed streams.
