Abstract: The described method and system utilize continuous and/or periodic measurement of the fuel pipes to detect leakage of fuel. In general, the piping is enclosed in an air-tight containment cover so that a passage is formed between the piping and containment cover. Measurements can be conducted, using known hydrocarbon and other combustible gases industrial analyzers, and leak detectors. Pressure drop within the passage can be compensated by controlling of air inlet flow into the passage, coordinated with the analyzer pumping rate. Temperature and motion of a gas sample can be controlled by heating the inlet air. The system can includes the controlling valves for the leak source localization. The described method and system can be used to analyze and control fuel leak for late lean injection system for combustor of a turbine.

Abstract: A furnace panel leak monitoring and control system for fluid-cooled panels in high temperature industrial furnaces such as, for example, smelting furnaces, blast furnaces and electric arc furnaces. The system performs at least two and up to four functions simultaneously. At minimum, the system includes one or more temperature sensors received within the body of the panel to monitor temperature within the metal of the panel itself, and pressure sensors installed proximate the inlet and outlet of each panel coolant fluid circuit, which circuits are preferably periodically automatically tested, to check for leaks in the coolant circuits. In addition, the system preferably includes temperature and flow sensors for monitoring the furnace panel coolant circuit(s) for temperature and flow fluctuations, respectively, which may be indicative of leaking cooling circuits. The system triggers visual and/or audible alarms to alert a human operator of an apparent coolant fluid leak situation.

Abstract: A safety device for shutting off the flow of gas to a gas-fired appliance in the presence of flammable vapors. A flammable vapor sensor is inserted in the circuit supplying a solenoid actuated valve with power from a thermocouple. The sensor responds to the presence of a flammable vapor with an increase in resistance. When a critical concentration of flammable vapors is achieved, the voltage drop across the sensor causes the solenoid actuated valve to close.

Abstract: A safety device for shutting off a gas valve at the detection of a gas leak has an add-on adaptor device having a first knob mounted over an existing gas knob and affixed thereto; a spindle coupled to the first knob, capable of rotating the fist knob, and the gas valve knob, between an open position and a closed position. A second knob is rotatably mounted substantially perpendicular to the spindle, and is provided with firm cantilever which is extended to provide a firm support along side the gas valve knob so as to cause rotation of the gas valve knob when the second knob is rotated in one direction. A spinning is attached to the second knob and is in a wound state when the second knob is parallel to the first knob when the first knob is in the open position, and in an unwound state when the first knob is in the closed position. A bracket is capable of being springably forced into a groove on the second knob when the second knob is aligned substantially parallel to the open position to keep it from rotating. A solenoid retracts the bracket away from the groove so the spring can rotate the second knob into the closed position. A fixing means fixes the add-on adapter device and holds the adapter in place on the existing gas valve knob. A gas leak detector detects the leaks and produces a signal to energize the solenoid and activate the device.

Abstract: A process gas supply system at the gas supply point includes an automated means for evacuating gas in a process line fed by the process gas supply system when an abnormal event occurs. The process gas supply system of this invention eliminates the need for any special valves or piping at the point of use of the process gas as well as the need for a return line from the point of use to the process gas supply system to purge the process line. A process gas is contained in a cylinder under pressure. The cylinder is coupled to a process line by the process gas supply system. The process gas supply system includes a gas flow controller and an automatic evacuation system. The gas flow controller controls the supply of the process gas from the cylinder to the process line. In an abnormal event, process gas flow from the cylinder is blocked by the gas flow controller and the automatic evacuation system evacuates the process gas not only from the gas flow controller, but also from the process line.
