Production method of coke oven gas and alternative fuel gas flow rate setting method of coke oven gas alternative fuel gas

摘要

PROBLEM TO BE SOLVED: To provide an alternative fuel gas which is calorifically stable without requiring reconstruction of combustion equipment on each using factory side.;SOLUTION: The mixing control method of natural gas and a dilution gas includes a step of setting an assumed dilution rate from an amount of the required pseudo C gas; a step of calculating the pseudo C gas composition and the controlled C gas composition from a natural gas composition, a dilution gas composition and C gas composition; a step of calculating a theoretical amount of air and a unit amount of heat generation from the controlled C gas composition, and determining whether the difference between the unit amount of heat generation and the unit amount of heat generation of C gas is within a set tolerance range or not; a step of setting the flow rate of a natural gas and the flow rate of the dilution gas from the determined dilution rate; and a step of modifying the setup flow rate of the natural gas and the dilution gas from the theoretical amount of air of the controlled C gas and the measured unit amount of heat generation.;COPYRIGHT: (C)2011,JPO&INPIT
