Natural Gas Tunnel Furnace

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.

FAQ

Q1: How is the gas consumption of a natural gas tunnel furnace calculated?

A:Gas consumption depends on the equipment size, set temperature, and production capacity. Under normal conditions, approximately 10-11 cubic meters of natural gas per hour are consumed for every 100.000 kcal of thermal energy.

Q2: If the factory does not have a natural gas pipeline, can liquefied petroleum gas (LPG) be used?

A:Yes. The burner nozzle only needs to be replaced with a suitable model and the gas supply pressure adjusted before delivery to adapt the equipment for LPG operation.

Q3: How does the equipment ensure safe natural gas operation?

A:The equipment is equipped with standard safety systems including high and low gas pressure protection, ultraviolet flame failure monitoring, automatic ignition, and forced furnace pre-purge systems to prevent combustion risks.

Q4: What material is used for the furnace mesh belt, and how long is its service life?

A:The furnace usually uses SUS304 stainless steel mesh belts or Teflon mesh belts, selected according to material characteristics. With proper maintenance, the service life of the mesh belt can reach more than 3 years.

Q5: Can different sections of the tunnel furnace be set to different temperatures?

A:Yes. The tunnel furnace can be divided into different zones such as the heating zone, constant temperature zone, and cooling zone. Each section is equipped with an independent temperature controller and heating system, supporting step-by-step temperature control according to process requirements.
