METHOD FOR REGULATING HEATING TEMPERATURE OF ATMOSPHERIC GAS AND HEATING TEMPERATURE REGULATOR

摘要

PROBLEM TO BE SOLVED: To solve the problem that the temperature of the atmospheric gas in a regenerative gas heater for continuously supplying the heated atmospheric gas is time sequentially changed, by providing >=3 regenerative heaters and successively switching the heaters to the burning state and the heating state and suction state of the atmospheric gas. SOLUTION: A cooling gas is mixed in the atmospheric gas discharged from the first regenerator of the regenerative heater in the atmospheric gas heating state.
