PURPOSE:To provide excellent load following-up properties, to enable continuous decreasing of a load, and to prevent production of clinker within a stop cell, by a method wherein the load of an operation cell is increased before the load is decreased to a specified value, and the stop cell is gradually decreased in a load. CONSTITUTION:Amounts of fuel and the air to a stop cell 21 are gradually decreased from a point D to a point K, and a fuel amount and an air amount are increased from a point J to a point G in the middle of a process in which amounts of fuel and the air to operation cells 22A, 22B, and 22C are decreased to a specified load. For example, in case a boiler load is decreased from 100% to 75%, amounts of the fuel and the air to the operation cells 22A, 22B, and 22C are increased from the point J to the point G before the load is lowered to a specified value. As noted above, in the operation cells 22A, 22B, and 22C, a layer temperature is increased from the point J to a point B as the amounts of the fuel and the air to the stop cell 21 are gradually decreased from a point E to the point K to decrease the load. |
