Double door roasting furnace is an industrial equipment used for material heat treatment (such as roasting, calcination, drying, etc.), characterized by having two furnace doors, usually designed for bidirectional operation or zone control to improve production efficiency and energy utilization. The following is a detailed introduction about the double door roasting furnace:
1. Basic structure and working principle
(1) Furnace body design:
Double door roasting furnaces usually adopt rectangular or circular structures, with one furnace door at each end for easy feeding and discharging. The interior of the furnace may be divided into multiple temperature zones, and zone heating is achieved through partitions or airflow control.
(2) Heating method:
Gas, fuel, electric heating, or microwave heating can be used to transfer heat to the material through radiation, convection, or conduction.
(3) Workflow:
Materials are loaded from one side of the furnace door, and after preheating, roasting, cooling, and other stages inside the furnace, they are taken out from the other side of the furnace door to achieve continuous or semi continuous production.
2. Main features
(1) Bidirectional operation:
The dual door design allows for simultaneous feeding and discharging, reducing downtime and making it suitable for large-scale continuous production.
(2) Temperature zoning control:
Accurate temperature regulation in different areas can be achieved through an independent temperature control system to meet various process requirements.
(3) Energy conservation and environmental protection:
Heat recycling (such as using waste heat from the discharge end to preheat the feed end) to reduce energy consumption; May be equipped with exhaust gas treatment systems (such as dust removal and desulfurization devices).
(4) Flexibility:
Suitable for different materials (such as ceramics, powder metallurgy, chemical raw materials, etc.) and processes (oxidation, reduction, carbonization, etc.).
