Abstract

PURPOSE: To prepare the title fuel of easy handling with greatly improved coal dispersion stability, by forming the mixture of pulverized coal with a heavy oil into slurry at a specific condition in the presence of a dispersing agent.
CONSTITUTION: A heavy oil containing at least 10 vol. % of high-boiling (550°C or more) components, such as crude oil, residual oil, etc. is mixed with pulverized coal. Within 30 mimutes from the beginning of thr above mixing, preferably after 1W30 minutes, the above two components are subjected to vigorous agitation in the presence of a dispersing agent at 60W150°C to yield a homogeneous slurry. The wt. ratio coal/heavy oil is fref. 6/4W3/7. The water content of the pulverized coal is 5 wt. % or less (usally 2W5 wt. %). As the dispersing agent, a surfactant is recommendable, whose necessary amount to be used is only 0.1W 2 wt. %, based on the total fuel system.
