Feature

De-wax furnace can burn toxic gas (binder) completely to smokeless and odorless (patented). Mixed gas stream of binder and air vaporized in a de-wax furnace adjusts flow rate with mixed gas of special heating structure of combustion furnace and is heated to 800℃ of complete combustion temperature.

Binder is burned completely and changed to one that is smokeless and odorless. The exhaust is mixed with air outside the equipment, cooled and discharged between a temperature range of 40-100 ℃.

• Temperature for usage： De-wax furnace：600℃max　Combustion furnace：800℃max
• Method to heat：De-wax furnace： All exhaust type hot wind heating method
  Combustion furnace：Circulation in case of Nitrogen Gas

Principle

Structure and principle of De-wax furnace：
①Air inlet： Air is suctioned from bottom.
②Heater unit： Heater temperature is controlled by PID.
③Propeller fan：Temperature distribution is uniformed by stirring and inverter control.
④Exhaust combustion furnace：Gas with binder exhausted out of de-wax furnace meanders in a long piping, is completely burned by 800 ℃ high temperature and becomes smokeless and odorless.
⑤Temperature decreasing exhaust tube：Equipment to decrease temperature to 100℃ after mixing gas of combustion temperature 800℃ with external air.
⑥Sirocco fan：This fan suctions from lower direction and emits from the side.
⑦Front door：Opens and closes in case of loading and unloading works and shelves with thermal insulation structure.
⑧Explosion dissipation safety door：Door is opened and internal pressure is dissipated in case that pressure is generated before an explosion with ignition inside de-wax furnace.

The reasons for explosions are as follows:

• Excessive processing of works
• Closed suction damper
• No exhaust processing
• Process of unknown works

Purpose

De-wax process of ceramic green molding products
