  • Patent number: 11946643
    Abstract: An air blowing fan supplies an amount of air corresponding to a fan rotation speed to a burner during operation. A check valve has a biasing force that closes an exhaust vent, and is opened and closed in accordance with a relationship between a gas pressure in an exhaust passage and the biasing force. A controller performs a failure diagnosis for detecting an open failure of the check valve when a phenomenon in which the gas pressure is lower than a predetermined normal pressure range is detected in a case where the fan rotation speed is within a predetermined diagnosis rotation speed region. The diagnosis rotation speed region is set within a rotation speed range in which a degree of opening of the check valve changes with an increase in the fan rotation speed when the check valve is normally opened and closed.

  • Patent number: 11920784
    Abstract: Flare gas is recovered by varying a number of ejector legs that depends on a flare gas flowrate. The ejector legs include ejectors piped in parallel, each ejector has a flare gas inlet and a motive fluid inlet. Flare gas and motive fluid is provided to ejectors by selectively opening or closing valves. The number of ejector legs online is varied to accommodate the amount of flare gas. The controller is also programmed to direct signals to actuators attached to the valves to open or close the valves, or to change the capacity of the ejector legs so they can handle changing flowrates of the flare gas. Included is a flare gas storage system with vessels made with flexible material, when flare gas is evacuated from the vessels, pressure in the vessels is maintained by compressing the vessels with an external force.
