Title:
BLOWER BRANCH PIPE, METHOD FOR MANUFACTURING BLOWER BRANCH PIPE, AND FURNACE BLOWING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/182097
Kind Code:
A1
Abstract:
The present invention provides a blower branch pipe, a method for manufacturing a blower branch pipe, and a furnace blowing system, that can prevent a safety accident in advance by monitoring whether a blower branch pipe is subject to damages, such as red-shortness, cracks, and deformation of a flow path, and can stably provide high-temperature air toward a melting furnace. To this end, the present invention comprises: a supply unit for supplying the high-temperature air to the melting furnace; a blower main pipe connected to the supply unit; a blower branch pipe that connects the blower main pipe and the melting furnace and supplies the high-temperature air from the blower main pipe to the melting furnace; and a temperature management module that determines whether the blower branch pipe is damaged by comparing the temperature of the blower branch pipe with a preset reference temperature, wherein the blower branch pipe comprises: a refractory layer having, on the inner surface thereof, a flow path in contact with the high-temperature air; a heat conductive layer disposed on the outer surface of the refractory layer and heated by heat transferred from the refractory layer; an external insulating layer disposed on the outer surface of the heat conductive layer so as to block heat of the heat conductive layer from being transmitted to the outside or external heat from being transmitted to the heat conductive layer; and a temperature sensor for sensing the temperature of the heat conductive layer.
