Abstract
Provided is a lance and an operation method using the same, in which a suction hole allowing source gas to be injected into a container, in which a reaction gas is generated, is included. The suction hole is formed in a source gas passage where the reaction gas is introduced into the passage. Thus the temperature of the gas injected into the container may be easily increased without using any separate heating device, and secondary combustion efficiency may be increased. In addition, the gas sprayed at a high temperature is provided, and thus additional heat may be supplied into the container. Thus, excessive use of fuel used to increase the temperature of the container may be avoided, and thus operation costs may be reduced and operation efficiency and productivity may be increased.
