Abstract
PURPOSE: To prevent back flow of liquid fuel and abnormal supply of liquid fuel securely, by automatically blocking the liquid fueld supply circuit when the calculated temperature difference of supply water and discharge water of tuyere cooling water is dislocated from the set temperature difference range.
CONSTITUTION: An arithmetic unit 10 calculates the difference of measured temperature sent in from thermometers 8, 9 provided in the midway between water supply pipe 6 to supply cooling water to a passage 3 in a tuyere 2 and water discharge pipe 7 to discharge water after cooling. Juding whether this calculated temperature difference is larger than or smaller than the set temperature difference inputted from a setting device 11, when the calculated temperature difference is dislocated from the set temperature difference range, a signal is sent to a heavy oil sequence 12, which automatically shuts off a heavy oil supply pressure circuit 13.
