• 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
• electrical heating system for combination with renewable energy sources, ex.g. bio gas fermenters
• separately control of the different heating zones 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 and large diameter process gas piping for safety operation(dust and tar!)
• 3 fully adjustable rectification columns for 3 different high quality fractions
• 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
