Abstract
A burner system for consuming waste fuel comprises a combustion unit having at least three combustion chambers arranged concentrically around a variable speed conveyor screw for directing the waste fuel along a fuel consumption path through the combustion chambers; an air chamber surrounding the combustion chambers to facilitate preheating combustion air delivered to the combustion chambers and to facilitate insulating the combustion chambers against thermal losses to the environment; a boiler in fluid communication with the combustion chambers for heating fluid to facilitate an energy conversion process; and an intelligent control system for controlling operation of the burner system. The control system controls operating parameters of the boiler including pressure, temperature and fluid level and activates an emergency stop alarm if any one of the operating parameters is outside a predetermined range of operating values.
