Title:
METAL MELTING FURNACE AND METAL MELTING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/136841
Kind Code:
A1
Abstract:
The purpose of the present invention is a metal melting furnace and a metal melting method that preemptively prevents ignition of exhaust gases, including carbon monoxide, in the vicinity of the exhaust vent and make it possible to preheat a metal material loaded into the furnace unit to efficiently melt the same. A metal melting furnace is provided with the following: a furnace unit (10), provided with a blower port (12) and a hot water outlet (11); a material storage chamber (21) that is adjacent to the upper part of the furnace unit (10) and is for storing a metal material; a material loading door (23) disposed at the border between the furnace unit (10) and the material storage chamber (21) so as to be openable and closable; a fuel burner (16) that is disposed near the base section of the furnace unit (10) and is for heating and melting the metal material; an ignition burner (17) disposed at the vertex section of the furnace unit (10); and a heat discharge passage (26) one end of which opens into the furnace unit (10) and the other end of which opens into the material storage chamber (21). The ignition burner (17) causes carbon monoxide contained in exhaust gases to react with oxygen fed from the blower port (12) to generate secondary exhaust gases, and the secondary exhaust gases are fed from the heat discharge passage (26) into the material storage chamber (21).
