• Torrefication
• Pyrolysis (Thermolysis)
• Carbonisation
• Gasification

• LTC (Low Temperature Conversion)
• Calcination
• Drying
• Cooling

Direct heated

• Burner inside rotary kiln
• Heat transfer by off gas
• Atmosphere inside rotary kiln with oxygen due to burning regulations
• Gas speed in reason of off gas amount relative high
• Maximum temperature only related of combustion parameters

Indirect heated

• Heating from outside the rotary kiln
• Heat transfer through rotary kiln shell
• Atmosphere variable adjustable
• Gas speed variable adjustable
• Maximum temperature only related of shell material

Advantages of DGE Thermolysis Systems

• continuous process for constant quality
• all equipment designed for longlife 24h/7d operation (minimum 100,000 hours values)
• extensive sensors for best quality as can be proved
• fully automatic control system
• automatic feeding system for man free shifts
• separately control of the burner systems for quick process changes
• automatic solid output with closed cooling systemfor highest fire and explosive protection
• solid storage with coal dust explosive protection equipment
• short process gas piping for safety operation(dust and tar!)
• quick cooling of process gas down under 100°C for using conventional gas equipment
• from type MAXI redundant condensation units for maintenance and cleaning during operation
• separation of solids and water in side stream of condensation unit
• cleaning of process gas to prevent expensive off gas cleaning units
• but still emmission control monitoring of clean exhaust gases for clean technology as can be proved
