摘要： PROBLEM TO BE SOLVED: To prevent local temperature rises of the interior wall of a combustor downstream of a combustor penetrating member. SOLUTION: A structure is provided with a combustor inner-cylinder shell 55 and a cylindrical heat insulating member 155 positioned inside the shell. On a heat insulating member 155D located downstream of the penetrating member 159 penetrating both the shell and the heat insulating member, a line of pin fins 155P is positioned which is composed of columnar protrusions protruding perpendicularly from the downstream outer peripheral part of the penetrating member. Since the line of pin fins 155P has a greater efficiency of heat transfer to and from cooling air than a fin-ring channel 155b provided in the portion 155U of the heat insulating member upstream of the penetrating member, the cooling ability of the heat insulating member increases at the downstream portion of the penetrating member so that, even if a vortex of combustion gas is generated on the wall surface of the heat insulating member downstream of the penetrating member by the presence of the penetrating member and causes a local increase in heat load on the wall surface, local temperature rises of the wall surface of the heat insulating member are prevented.

摘要： PURPOSE:To deposit a clathrate hydrate in a transporting pipe and to stably disperse the clathrate hydrate in the deep sea after removal of reaction heat by providing a land pump for forcibly feeding a mixture composed of the sea water and carbon dioxide and the transporting pipe provided with a cooling pipe for circulating a refrigerant back and forth down to the transporting end at the depth of the clathrate forming area in the sea on the pipe wall. CONSTITUTION:The concentrated carbon dioxide and sea water are pressurized and mixed in the transporting pipe 5 down to the deep sea by the land force freed pump 4 to progress the reaction to form the clathrate hydrate. The generated reaction heat is removed by the heat exchange in the transporting pipe 5 by the cooling water flowing in the cooling pipe 5' provided to the front end along the pipe wall of the transporting pipe 5 from the cooling device 6. The formed carbon dioxide clathrate hydrate 7 is stable without decomposing and has a large sp. gravity and does not, therefore, float when the clathrate hydrate is released and dispersed into the deep sea within the range of the carbon dioxide clathrate hydrate forming conditions. The possibility of the ecological environmental destruction by the temp. rise of the sea water arising from the reaction heat and the decomposition of the clathrate hydrate by the rise of the ambient temp. in the deep sea is eliminated.

摘要： PURPOSE:To ensure that the efficiency of a solid/air reaction in a last stage by detecting the humidity of a reactor tower outlet gas and adjusting the amount of a hygroscopic material to be added to an alkaline agent slurry which is supplied to a reactor tower, based on a detection value within a specific rate range against the alkaline agent. CONSTITUTION:A hygroscopic material is dissolved in water in a hygroscopic material dissolution tank 21 and the dissolved material is connected to a Ca(OH)2 slurry transport line using a pump 22. Then the amount of the injected dissolved material is controlled by detecting a moisture value in an exhaust gas with a humidity detector 24 arranged an exhaust gas discharge pipe 4, and transmitting the moisture value to a flow adjustment valve 23 using a converter 25. That is, the amount of the hygroscopic material to be added to Ca(OH)2 slurry which is supplied to a reaction tower is adjusted within the range of 5 to 15mol% of Ca(OH)2. Subsequently, the last stage solid/gas reaction between Ca(OH)2 powder and SO2 gas is accelerated to allow the solid/gas reaction efficiency to increase. As a result, the overall SO2 removal efficiency reaches about 80 to 90% values.
