A direct-fired generator for an absorption refrigerator configured as described above (hereinafter,
In this generator), from the tube (4) to the smoke chamber (5)
Although the combustion gas which has been inverted and flowed into the passage (6) for combustion gas flows upward while flowing from the upstream side to the downstream side of this passage, the rise is suppressed by the fins of the solution pipe. Since the flow of the combustion gas is directed downward, the amount of the combustion gas flowing through the bottom of the passage is larger than that in the case where only the solution pipe having no fin is provided in the passage (6). That is, the fins formed on the outer periphery of the upper portion of the solution pipe serve as a guide for guiding the flow of the combustion gas in the passage (6) downward. Moreover, in this generator, many fins are formed on the upper outer periphery of the solution tube toward the downstream side of the passage (6) while the smooth surface of the lower outer periphery is reduced, so that the passage of the combustion gas in a horizontal passage is reduced. (6) It is possible to effectively prevent the gas flow from gradually rising and being biased upward on the downstream side while flowing through the inside. Therefore, in this generator, the gas flow velocity distribution in the combustion gas passage is less uneven and the temperature unevenness is smaller than in the conventional generator in which only the solution pipe without fins is provided in the horizontal combustion gas passage. As a result, it is possible to more uniformly heat and concentrate the combustion gas and the absorbing liquid, and it is possible to improve the concentration efficiency.
For example, when a combustion test is performed with a conventional generator in which the fins are removed by setting the ratio of the vertical length to the horizontal length of the combustion gas passage (6) to 0.4, and this generator is compared. It was confirmed that the gas temperature in the exhaust gas smoke chamber (7) of this generator was about 80 ° C lower than that of the conventional one. As can be seen from the test results, it is clear that the efficiency of heating the absorption liquid by the combustion gas in the combustion gas passage of the present generator is higher than that of the conventional one.
