Abstract

PURPOSE: To continuously prepare simply and efficiently a pulverized coal as a fuel, by sending a lump coal and LNG to an ultralow-temp. crusher, and embrittling and pulverizing the coal by cooling to an ultralow temp.
CONSTITUTION: In a step prior to the introduction of NLG to a vaporizer, a lump coal is introduced into a pulverizer for the ultralow-temp. freeze pulverization of coal and sent to the vaporizer after cooled to an ultralow temp. The pulverizer is equipped with a compressive crusher, a sieve, etc. The operation is continuously carried out automatically under remote control. There is no danger of dust explosion, etc., and safe and continuous operation is possible, because the apparatus and the discharged pulverized coal are at an ultralow temp. even if the coal is pulverized.
