GAS COMBUSTION EQUIPMENT

PROBLEM TO BE SOLVED: To provide gas combustion equipment automatically realizing optimization of a blast quantity corresponding to fuel gas actually supplied to the gas combustion equipment and a blast quantity corresponding to the variation of actual operating environment during the continuation of operation, without going through special processing. SOLUTION: Fan rotating speed X is corrected by 5% if a CO concentration detection value in combustion exhaust gas generated in a stable combustion state is 300 ppm or more (NO in S3). An increase side correction is made if a flame temperature detection value by a burner sensor is higher than 300°C (YES in S6, and S7), and a decrease side correction is made if it is lower than 300°C (NO in S6, and S8). X is corrected by 2% if the CO concentration detection value is 200 ppm or more (NO in S4). An increase side correction is made if the flame temperature detection value is higher than 300°C (YES in S9, and S10), and a decrease side correction is made if it is lower than 300°C (NO in S9, and S11). X is used as it is without correction if the CO concentration detection value is less than 200 ppm (YES in S4, and S5). COPYRIGHT: (C)2005,JPO&NCIPI
