COMBUSTION AIR VOLUME CONTROL METHOD IN ASH MELTING FURNACE

Japanese Patent JP2617830

B2

PURPOSE: To control an amount of combustion air to be supplied to an ash melting furnace to the most suitable amount corresponding to an actual amount of combustion air.
CONSTITUTION: In the case that an amount of combustion air of an ash melting furnace 1 for electrically melting fed burnt ash is to be controlled, a supplied amount of electrical power for the ash melting furnace 1 and a theoretical amount of air calculated by the fed amount of ash are added with a correction of reduction of air volume proportional to a difference between the set value and a detected value of a furnace temperature when the furnace temperature is less than the set value, an increased correction of air volume proportional to a detected value of carbon mono-oxide at an outlet of the furnace and an increasing or decreasing corrected value proportional to an increasing or decreasing of the detected value of the oxygen gas at the outlet of the furnace from the set value so as to determine the amount of combustion air.
