PROBLEM TO BE SOLVED: To provide a combustion control system for a combustion control system for a dry gasifying combustion apparatus capable of stably actuating a dry gasifying furnace, a secondary combustion furnace, and a waste heat recovery apparatus from the starting of operation to completion. SOLUTION: A combustion control system for a dry gasifying combustion apparatus is adapted such that it includes a dry furnace 4 for combusting a solid fuel supplied from a solid fuel supply apparatus, a combustion furnace 15 for combusting dry distillation gas supplied from the dry distillation furnace 4, and a waste heat recovery apparatus 25 for recovering heat of combustion gas supplied from the combustion furnace 15. In the system, a primary air adjusting valve 28 is disposed on an fan air tube 18 for supplying primary air to the dry distillation furnace 4, and a load variation detector 26 is disposed on the waste heat recovery apparatus 15 for detecting a heat inflow requirement of the waste heat recovery apparatus 15. Opening and closing of the primary air adjusting valve 28 is controlled such that, when the heat inflow requirement of the waste heat recovery apparatus 15 is severely greater, an opening is increased using a signal from the load variation detector 26 while, when the heat inflow request is smaller, the opening is reduced. |
