<p>Method of eliminating a combustible material enveloping solid fragments, such as cutting oil enveloping machining chips, while recovering its thermal energy, and device for carrying out said method. By means of a worm 3 the chips are dropped into the extension of the flame of a burner 6 in order to ignite the oil. After separation in a cyclone 8, the fumes are discharged via the flue 9, and the preheated chips are recovered for melting. The combustion is oxidising in all respects. The temperature of the fumes is kept constant by continually adjusting the air flow and gas flow to take into account any variations in the flow of chips and the contents of combustible and incombustible matters. The regulation is organised so as to make the greatest possible saving of added fuel. Application in the removal of oil from chips enveloped in cutting oil for the purpose of melting them, in regenerating foundry sand and in incinerating industrial sludges. <IMAGE></p> |
