摘要
A method of and apparatus for controlling the feed amount of air for combustion in a natural draft type heating furnace is disclosed, in which the draft pressure, the oxygen concentration in a combustion gas, the opening degree of a damper for controlling the flow rate of the combustion exhaust gas, the flow rate of a fluid to be heated and the temperatures of the fluid to be heated at inlet and outlet portions of the heating furnace are measured, and the feed amount of air for combustion is controlled based on measured values obtained at predetermined time intervals or corrected values thereof.
