Regulating and controlling unit for burning process in cremation furnace e.g. electric arc furnace, of cremation system, controls combustion air admission through combustion air blower by measuring oxygen concentration in zones of furnace

摘要

The regulating and controlling unit controls combustion air admission through an individual regulatable combustion air blower by measuring oxygen concentration in multiple zones of a cremation furnace with the aid of sensors e.g. oxygen sensors, of the cremation furnace. The sensors are installed between a main combustion chamber and an auxiliary combustion chamber and behind the auxiliary combustion chamber, or directly at stack gas flue.
