Gas-Fired Baking Tunnel Furnace

A gas-fired baking tunnel furnace is an efficient industrial heating equipment that generates heat through the combustion of fuel gas (natural gas or liquefied petroleum gas). It uses a continuously operating conveyor belt to transport materials into a tunnel-shaped drying chamber for uninterrupted continuous baking.It is mainly composed of a furnace body, gas heating system, transmission and conveying system, moisture exhaust and smoke exhaust system, and intelligent central control system.

The furnace adopts multi-section independent temperature control. The upper heating and lower heating can be adjusted separately to ensure uniform heating of materials.

Extremely High Production Capacity:

The equipment operates continuously through an assembly line production mode, with a high level of automation, effectively reducing labor requirements and increasing production output.

Safe and Reliable:

The equipment is equipped with automatic ignition, flame failure protection, gas leakage alarm, over-temperature gas shut-off, and multiple safety protection mechanisms.

FAQ

Q1: Which one is more cost-effective, a gas-fired tunnel furnace or an electric heating tunnel furnace?

A1: A gas-fired tunnel furnace. Under the same production capacity conditions, the gas cost is usually 30% to 50% lower than the electricity cost.

Q2: What should be done if the temperature inside the tunnel furnace is uneven?

A2: The equipment adopts multi-section independent temperature control and hot air circulation technology. The upper heating and lower heating configurations of each section can be adjusted separately through the temperature control instrument.

Q3: How does the equipment ensure the safety of gas usage?

A3: The system integrates flame failure protection, abnormal gas pressure alarms, and automatic shut-off valves. Once an abnormal condition is detected, the system will close the gas valve within milliseconds.

Q4: What materials are generally used for the conveyor belt?

A4: For food-grade applications, stainless steel mesh belts or carbon steel chain plates are selected. For industrial applications, Teflon mesh belts or manganese steel mesh belts can be selected according to the characteristics of the materials.

Q5: Can the external dimensions of the equipment be customized according to our factory space?

A5: Yes. The total furnace length, conveyor belt width, feeding and discharging section height, and heating zone divisions can all be customized according to the factory layout requirements.
