Title:
OPERATIONAL METHOD OF WASTE GASIFICATION MELTING FURNACE
Document Type and Number:
Japanese Patent JP2017032187
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a waste gasification melting furnace capable of sufficiently suppressing increase of fuel to be introduced into the furnace in a case of operation that an open hole for discharging molten material is steady opened, and capable of sufficiently preventing the open hole from being closed due to temperature drop of the molten material at the open hole and around its surroundings, and provide an operational method therefor.SOLUTION: A waste gasification melting furnace includes: a melting furnace part positioned on a furnace bottom side; an open hole formed from an inner surface of the melting furnace part to an outer surface thereof; a pressure holding chamber arranged outside the melting furnace part, and having an internal space communicating with the open hole; and a burner arranged in the pressure holding chamber, and configured to add heat to molten material discharged from the open hole. The pressure holding chamber can maintain pressure in the pressure holding chamber so as to be larger than pressure in the melting furnace part.SELECTED DRAWING: Figure 1
