Abstract

PROBLEM TO BE SOLVED: To cause fire-extinguishing agent to surely inject in a combustion device when the inside of the combustion device is heated up to dangerous temperature by a method wherein there is provided a plug member for closing an outlet port of a fire extinguishing bomb, opening the injection outlet port when the dangerous temperature occurs in the combustion device to cause its heat to melt the plug member so as to enable flame-extinguishing agent to be injected into the combustion device. SOLUTION: A flame-extinguishing bomb is arranged at a high location of an inner left side of a combustion device and then water, N2 , CO2 and other flame- extinguishing agents containing powder are filled in the flame-extinguishing bomb. An injection port of the flame-extinguishing bomb is directed into a gas discharging port cover and the injection port of the flame-extinguishing bomb is closed by a plug member 75. The plug member 75 is formed by raw material which is melted at a high dangerous temperature. During normal operation, although the plug member 75 closes an outlet of the flame-extinguishing bomb, as the inner side of the combustion device reaches a dangerous temperature during operation or due to certain external causes, the plug member 75 is melted with heat to open the injection port, resulting in that the flame-extinguishing agent is injected into the discharged gas port cover.

However, in such a conventional extinguishing apparatus for a combustor, if a fire does not occur from the combustor, the fire extinguishing equipment will not operate reliably, and the fire will not occur or the fire will be small. Fire extinguishing equipment does not always operate at a stage of scale, so we do not deal with fires quickly,
Moreover, since the extinguishing agent is ejected from the outside of the combustor toward the combustor, there is a problem that it cannot be said that the fire is extinguished efficiently. The present invention has been made in view of such a conventional problem, and when the combustor is overheated to a dangerous temperature, the extinguishant is surely ejected in the combustor. It is an object of the present invention to provide a fire extinguisher in a combustor, which can prevent the occurrence of a fire and can quickly and efficiently deal with a fire.

Furthermore, during normal operation, the water source side port for supplying water from the water source side to the heat exchanger side, which is the water supply side, has a dangerous temperature inside the combustor,
Similarly, the drive unit 62 outputs a drive signal to the switching valve actuator 81, the switching valve 82 is switched, and the opening port 8 is opened.
Connect to 3. As a result, the water supply is jetted out into the exhaust port cover through the opening 83. During normal operation, the water to be supplied to the heat exchanger side is switched for fire extinguishing, so there is no need to purposely prepare a fire extinguishing cylinder, etc.
The fire can be extinguished more efficiently and more reliably. Further, when the switching valve 82 is switched, the switching information is input to the storage unit 61, and similarly, the calculation unit 64 calculates the switching information, and the drive unit 62 outputs the drive signal to the main valve actuator 41a. The gas solenoid valve 41 is closed.
