(C) Problems to be Solved by the Invention In the above-mentioned conventional technology, in the finned tube group, the passage of the combustion gas is narrowed by the fins. For example, when the direct-fired generator is made of heavy oil, it is contained in the fuel. The sulfur, carbon, and other unburned matter adhered to the fins, and when the amount of the unburned matter increased, there was a problem that the adhered matter became an obstacle to the combustion gas. In addition, if the flow of combustion gas becomes worse due to the sulfur attached to the fins and the resistance (furnace pressure) in the flue rises, it becomes difficult to send air into the generator with the burner's blower, resulting in a lack of oxygen. This causes a problem that poor combustion occurs and soot is further generated. Also, if soot adheres to the surface of the solution pipe and the flue iron plate, the amount of heat collected in the flue will decrease.If the burner is burned with the same amount of combustion as before sooting, the flue temperature will decrease. As a result, there has been a problem that the temperature of the flue rises and the surface temperature of the iron plate in the flue rises, making it easy to corrode.

In addition, the solution tubes are arranged in a zigzag pattern to improve the heat transfer performance, and the intervals between the fins and between the uppermost and lowermost fins and the upper and lower surfaces of the flue are narrow. Therefore, it has been difficult to perform a cleaning operation when unburned matter adheres to the fins.
