CCR
<strong>TCF</strong> - <strong>Recycling</strong> Technology<br />
ideal burner arrangement<br />
best heat transfer to the bath surface<br />
continuous, safe combustion of pyrolysis gas<br />
equal preheating of combustion air<br />
continuous control of the fuel/air ratio<br />
reliable quenching of all the flue gas<br />
no afterburner equipment<br />
equal waste gas temperature at the FPP<br />
