Natural Gas Tunnel Furnace
Category：Tunnel Oven Production Line
Introduction
The Natural Gas Tunnel Furnace is a large-scale industrial heating and baking equipment that utilizes a continuous tunnel structure for efficient heating processing. Powered primarily by natural gas, the equipment uses an advanced combustion system combined with hot air circulation or radiation heating technology to complete processes such as drying, curing, baking, and aging while materials are continuously transported through the conveyor system.
Applications
Food Industry:
Used for continuous large-scale baking of bread, biscuits, pastries, and meat products.
Coating Industry:
Used for curing surface coatings after spray painting of automotive parts, hardware components, plastic parts, and other products.
Electronic and Electrical Industry:
Used for drying and aging processes of transformers, motor windings, and circuit boards after impregnation treatment.
New Materials Industry:
Used for high-temperature dehydration, drying, and sintering of chemical materials, ceramics, composite materials, and other products.
