Method for increasing temperature of mixture by using ignition furnace

The invention discloses a method for increasing the temperature of a mixture by using an ignition furnace, which comprises the following steps of: adding a quick switching valve at an inlet of a steam pipeline which is introduced into a material distribution bin, then leading out another white steel pipe with the same diameter from the front edge of the quick switching valve, and connecting the white steel pipe to an outlet of a heat preservation section of the ignition furnace; a steam white steel pipe penetrates through the heat preservation section of the ignition furnace from one side to the other side, turns back and goes back and forth for multiple times after approaching refractory bricks on the inner wall of the ignition furnace, finally comes out of an inlet of the heat preservation section of the ignition furnace, and stays in the ignition furnace, so that the temperature of the steam can be at least increased by a certain temperature; a reciprocating snakelike coil pipe is arranged in the electric
