Ignition furnace

Abstract

The present invention provides an ignition furnace that can appropriately suppress the inflow of crosswinds into the furnace even when the height of the sintering material on the pallet trolley changes. [Solution] The ignition furnace (10) comprises a furnace body (11), an inlet plate gate (13), an outlet plate gate (14), a height detection device (15), an inlet lifting device (18), an outlet lifting device (19), and a control device (20). The inlet plate gate (13) is provided adjacent to the inlet end (11a) of the furnace body (11) and is movable up and down. The outlet plate gate (14) is provided adjacent to the outlet end (11b) of the furnace body (11) and is movable up and down. The height detection device (15) detects the height of the sintering material on the pallet trolley (2). The inlet lifting device (18) raises and lowers the inlet plate gate (13). The outlet lifting device (19) raises and lowers the outlet plate gate (14). The control device (20) controls the inlet lifting device (18) and the outlet lifting device (19) based on the height of the sintering material.

Claims
