摘要： PROBLEM TO BE SOLVED: To smoothly restart a combustion engine by preventing liquefaction of dimethyl ether (DME) in a fuel supply line during the stop of the combustion engine such as a gas turbine vaporizing DME for use as fuel.
SOLUTION: A discharge valve 14 for discharging DME of fuel into the atmosphere is connected to the fuel supply line 10, and the discharge valve 14 is opened when intercepting the supply of fuel to the combustion engine to stop it. Pressure in the fuel supply line 10 is lowered to the atmospheric pressure by opening the discharge valve 14, and since DME is not liquefied even at a low temperature under the atmospheric pressure, it is not liquefied in the line. Consequently, since there is no blocking of the fuel line caused by DME sticking as liquid to equipment or the like in the line, the following starting can be smoothly performed.

摘要翻译：要解决的问题：在内燃机停止期间防止燃料供给管线中的二甲醚（DME）的液化，例如用作燃料的燃气轮机汽化DME，以平稳地重启内燃机。解决方案：用于将燃料DME排放到大气中的排出阀14连接到燃料供应管线10，并且当截留向内燃机的燃料供给停止时，排出阀14打开。通过打开排出阀14将燃料供给管线10中的压力降低到大气压，并且由于即使在大气压下的低温下DME也不液化，因此在管线中不液化。因此，由于DME由于液体向管线中的设备等而粘附而导致的燃料管路不阻塞，因此能够平稳地进行以下的启动。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a combustion vibration analysis method and its device relating to combustion vibration control to be induced with pressure fluctuation in a combustion process in a combustor, and to provide a medium on which an analysis program is recorded for executing a computer using the analysis method.
SOLUTION: The combustion chamber 13 is divided into a plurality of cavities which are connected together via communication pipes 29.

In accordance with the sizes of the cavities 27, 28, the resonator 22, the communication pipes 29 and the throat, the frequency response property of the Helmholz vibration to the vibration exciting frequency of the pressure source is calculated to evaluate the vibration damping effect of the resonator 22 and derive the frequency response property of the pressure and the flow rates from numeric calculation.
