    • PURPOSE:To control an air blasting quantity and a gas quantity and obtain a burning controller capable of safely burning a gas burning boiler by providing an intermediate value computing element for dividing its difference into several parts to change the output in an aimed data value stagedly when output data is changed to a next output data. CONSTITUTION:The difference of existing data and the output data output from a main controller 21 composed of a PID computing element 23, a load position determining computing element 25, an output data selecting computing element 24 and the like is divided into several parts by an intermediate value computing element 38. A lifting detector 37 judges whether the several parts- divided data are output in the direction in which they are larger than the existing data or smaller than the existing data. The output for a servo controller 40 of a gas supply valve 44 is performed at the time when data signals agree with the divided output data in the case where the divided data is larger than the existing data. In the case where the divided data are becoming smaller than the existing data, the output is performed for an air damper 45 after pulse data are agreed with them. Therefore, accidental fire of air shortage can be prevented.
