  • Process for maximizing combustion of fuels
    Patent number: 4091614
    Abstract: A process for maximizing combustion of fuels and maximizing thermal efficiency by cooling between or after combustors with heat recovery exchanges as steam generators or superheaters. Excess combustion air requirements are minimized by the utilization of metal oxides to provide oxygen by reaction with steam and producer gas.
    Type: Grant
    Filed: September 9, 1976
    Date of Patent: May 30, 1978
    Inventor: Arnold Marcel Leas
