a flue disposed above the furnace in communication with the rear of the furnace, and a solution flow path formed between the flue, the furnace and the vessel body,
Additionally, a direct-fired generator is disclosed in which a solution flow path is formed between the rear tubesheet of the furnace and the rear tubesheet of the vessel body. and,
When this direct-fired generator is in operation, a burner facing the furnace forms a flame within the furnace, which heats the rear tubesheet of the furnace. Steam bubbles generated from the solution due to heating of the rear tubesheet rise through the solution flow section.

生するおそれがあった。(c) Problems to be Solved by the Invention Most of the steam bubbles generated during the operation of a direct-fired generator are caused by the relatively wide solution flow path between the rear tube sheet of the furnace and the container body and the rear tube sheet of the container body. Therefore, the solution rising in the solution flow path had a horizontal component, and the rising speed of the solution was slow. For this reason,
The solution at the bottom of the solution flow path between the rear tube sheet of the furnace and the rear tube sheet of the vessel stagnates, and the amount of heat transferred from the furnace and the lower part of the rear tube sheet of the furnace to the solution is small. The high temperature of combustion gas flows into the flue. Then, the flue inlet was heated by the high-temperature combustion gas, and there was a risk that the flue inlet would be corroded by the solution.

24) The steam bubbles generated on the side surface are caused by multiple plates (7)...
Since the horizontal component of the flow of steam bubbles is slightly suppressed by each plate (7), the rate of rise of the steam bubbles becomes faster. Therefore, the absorption liquid at the lower part of the solution flow path (24) is sucked up by the bubble pump effect generated in the solution flow path (24), and the flow of the absorption liquid becomes active. and,
The amount of heat transfer on the liquid side increases and the flow from the furnace tube (4) to the flue (11) increases.
As the temperature of the combustion gases flowing into the flue (11) decreases,
This makes it possible to prevent corrosion on the inlet side. In addition, each plate (7)... increases the heat transfer area on the liquid side of the rear tube plate (6) of the furnace cylinder, increasing the amount of heat exchange between the dilute absorption liquid and the combustion gas, and improving the heating efficiency of the dilute absorption liquid. It becomes possible to improve

27)..., the horizontal component of the flow of steam bubbles is slightly suppressed, and the rising speed of the steam bubbles becomes faster. Then, the absorption liquid at the lower part of the solution flow path (24) is sucked up by the bubble pump effect generated in the solution flow path (24), and the flow of the absorption liquid becomes active. Therefore, the amount of heat exchange on the liquid side increases and the temperature of the combustion gas flowing from the furnace # (11) to the flue (11) decreases, avoiding overheating on the inlet side of the flue (11) and preventing corrosion.
