METHOD OF HANDLING SUBSTANCE FROM WHICH COMBUSTIBLE GAS VOLATILIZES, PROCESS FOR PRODUCING SOLID FUEL, METHOD OF STORING SOLID FUEL, METHOD OF USING SOLID FUEL, AND APPARATUS USING SOLID FUEL

摘要

A handling method by which a substance from which a combustible gas volatilizes is inexpensively and safely mixed, stored, and otherwise handled. The method of handling a substance from which a combustible gas volatilizes comprises handling the substance in a highly closed apparatus, and is characterized in that air is introduced into the highly closed apparatus and the substance from which a combustible gas volatilizes is handled while keeping the combustible gas which has volatilized in the state of being diluted to a concentration at which neither an explosion nor a fire occurs. In the method of handling a substance from which a combustible gas volatilizes, air is used to dilute the combustible gas to a concentration at which neither an explosion nor a fire occurs, without the need of an inert gas, such as nitrogen or carbon dioxide, which is required to be produced or purchased. Thus, a substance from which a combustible gas volatilizes can be handled inexpensively and safely in operations such as mixing, storage, etc.
