【発明の詳細な説明】 （イ） 産業上の利用分野 本発明は直焚発生器に係り、特に吸収冷凍機に使用され
る直焚発生器（以下、発生器という）に関する。TECHNICAL FIELD The present invention relates to a direct-fired generator, and more particularly to a direct-fired generator (hereinafter referred to as a generator) used in an absorption refrigerator.
（ロ） 従来の技術 臭化リチウム−水系の吸収冷凍機に使用される発生器の

水平に流すものが知られている。(B) Conventional Technology As a conventional technology of a generator used in a lithium bromide-water absorption refrigerator, for example, as shown in Japanese Utility Model Publication No. 45-15729, a rectangular container for absorbing and discharging an absorbing liquid is used. A plurality of parallel rectangular hollow shunts (absorption liquid passages) that communicate with each other at both ends are formed, and a heater [in the heating cylinder (furnace and flue)] formed between these shunts It is known that the flame and the combustion gas from the burner are sent from the bottom to the top, while the absorption liquid in the shunt flows substantially horizontally along with the bubbles of the vapor from the rear to the absorption liquid outlet in the front.

る。Further, a generator that causes the absorption liquid in the shunt (absorption liquid passage or solution pipe group) to flow in a substantially horizontal direction and the combustion gas in a furnace tube and a flue to flow in a substantially horizontal direction is, for example, Japanese Utility Model Publication No. 55-482.
It is also disclosed in Japanese Patent Publication No. 44 and Japanese Utility Model Publication No. 57-54531.

微弱電流の作用で発生器の構造部材の腐食を早める問題
点があった。(C) Problems to be solved by the invention In a conventional generator in which the absorption liquid in the shunt (absorption liquid passage or solution pipe group) is caused to flow in the horizontal direction, the upper part of the shunt has a light absorption liquid or odor. The absorption liquid with a low concentration of lithium bromide easily flows, while the heavy absorption liquid, that is, the absorption liquid with a high concentration of lithium bromide easily flows in the lower part of the shunt, so the concentration distribution of the absorption liquid in the shunt is uneven. It is easy to become. This also applies to the concentration distribution of inhibitors such as lithium molybdate and lithium chromate that are filled in the absorbing solution as rust preventives for the structural members of the generator. Therefore, in the conventional generator, there is a problem that after the heating is stopped, crystal breakdown of lithium bromide is likely to occur in the lower part in a large number of shunts, and a weak current generated by the difference in concentration causes There is a problem of accelerating the corrosion of structural members.

スと吸収液との熱交換量が多い反面、煙道のガス下流部
やガス下流側の両側部での熱交換量が少ないという問題
点もあった。In addition, in the conventional generator in which the combustion gas flows in the flue in a substantially horizontal direction, the heat exchange amount between the combustion gas and the absorbing liquid is large in the gas upstream part and the central part of the flue, but the gas downstream of the flue part is large. There was also a problem that the amount of heat exchange in both parts and both sides of the gas downstream side was small.

としたものである。In view of these problems, the present invention is capable of reducing the crystals of the absorbing liquid and reducing the corrosion of the structural members, and the heat of the combustion gas and the absorbing liquid in the downstream portion and the downstream side portions of the flue. The purpose of the present invention is to provide a direct-fired generator capable of improving exchange.

る構成としたものである。(D) Means for Solving the Problems As a means for solving the above problems, the present invention forms the flue of the generator in communication with the rear of the furnace and forms it substantially horizontally above the furnace tube. And, an outer fin projecting solution pipe group (shunt) communicating with the solution flow section as a solution storage section surrounding the flue is provided vertically on both the downstream side and the downstream side of the flue and at the other parts of the flue. Is a structure in which a solution tube group having a smooth outer surface is vertically provided.

抑制されるので、発生器の構造部材の腐食が緩和され
る。(E) Action In the generator of the present invention, when heated, the absorbing liquid in the solution tube group is stirred by convection in the solution flow section while moving from the bottom to the top together with the bubbles of the vapor, so that these tube groups are agitated. The effect of promoting the homogenization of the concentration of the absorbing solution inside is exhibited. Due to this action, the deviation of the concentration of the absorbing solution [the concentration of lithium bromide, the concentration of the inhibitor] in the solution tube group is reduced and the generation of the weak current is suppressed, so that the corrosion of the structural members of the generator is reduced.
かつまた、溶液管群の配備されている煙道が炉の上方に

なわち臭化リチウム濃度の高い吸収液が溶液管群内に滞

液の結晶を生じることも殆んどない。Also, since the flue where the solution tube group is installed is located above the furnace and the solution tube group is located above the solution storage part, the heavy absorption liquid is not supplied during the heating suspension of the generator. That is, the absorbing solution having a high concentration of lithium bromide hardly stays in the solution tube group. Therefore, crystals of the absorbing liquid are hardly generated in the solution tube group.

生全体としての熱交換も向上する。In addition, since fin fin solution tube groups are provided on the downstream side and both sides on the downstream side of the flue, the heat exchange area between the combustion gas and the absorbing liquid in these parts increases by the area of the fins, and the entire generation occurs. The heat exchange as is also improved.

って本発生器の寿命が大幅に延びる。In the generator configured as described above (hereinafter referred to as the present generator), when heated, the heat of the combustion gas flowing through the flue (3) causes solution tubes (4a), (4b) ...
The absorbing liquid [lithium bromide aqueous solution] boils inside 8), (18), and vapor is generated. Also in the solution flow section (16), the absorbing liquid vigorously boils due to the flame of the burner (B) and the heat of the combustion gas to generate steam. Then, the absorbing liquid moves from the lower part to the upper part in the passages (18), (18), etc. together with the generated vapor bubbles, and these passages and the solution flowing portion (16),
(17) The absorption liquid is agitated while convection in the solution storage portion formed by (1) and (2). As a result, the homogenization of the lithium bromide concentration of the absorbing liquid in the solution storage section is promoted. Also,
This also applies to the concentration of lithium molybdate filled in the absorbing solution as a rust preventive. Therefore, the bias of the concentration in the solution storage portion is reduced, the movement of ions due to this bias, in other words, the generation of a weak current is suppressed, and the corrosion of structural members such as the solution pipe due to the action of the weak current is mitigated. It Particularly, when the solution portion between the opening peripheral edge of the solution pipe and the outer wall of the flue (3) is corroded, stress corrosion cracking is likely to occur, so that the corrosion of this weld portion is mitigated, and the life of the generator is greatly extended.

Also in (13), (14), (15), (16) and (17),
As in the case of the solution storage section described above, the absorption liquid is stirred while convection, so that its concentration becomes substantially uniform.

休止中の結晶にくらべ、加熱再開時の支障は小さい。Further, the passages (18), (18), that is, the solution pipes (4),
The concentration of the absorbing liquid in (4) ... Is almost uniform when the generator is heated, and the absorbing liquid in the solution tubes (4), (4) ... is the liquid phase in the body (1). Since it is located at the upper part of the section, the probability that crystal of the absorbing solution will be generated in the solution pipes (4), (4), etc. while the heating of the generator is stopped is small. For this reason, there is no possibility of seriously disturbing the concentration of the absorbent during reheating of the generator. However, in the solution flow section (15) located at the bottom of the liquid phase part, the absorption liquid that became cold and heavy during the rest of heating of the generator, that is, the absorption liquid with a slightly higher concentration than the upper layer, is likely to exist. Although the probability of the crystal is high, this crystal is easily melted by the heat of the high-temperature flame of the burner (B) when the heating is restarted, so the crystal in the solution tube (4), (4) ... Compared to the above, there is less trouble when resuming heating.

a) ... is provided in the downstream part of the flue (3) and both side parts on the downstream side, so that the heat exchange amount between the combustion gas and the absorbing liquid in these parts is higher than that of the finless solution pipe. Compared to the case where it is installed in a part, it increases by about 5% [this was confirmed in the experiment], so the thermal efficiency of the whole generator is improved and the concentration ratio of the absorbing liquid is also increased. In addition, this is flue (3)
The same is true for a generator of the type in which is connected at the same height as the furnace (2).
