摘要： An integrated coal gasification combined cycle (IGCC) plant which appropriately processes an early produced gas to suppress the emission of a sulfur component into the atmosphere for further improving environmental compatibility is provided. The IGCC plant has a gasifier for converting pulverized coal to gas fuel, a gas turbine operated thereby and supplying a combustion exhaust gas to an heat recovery steam generator, a steam turbine operated by steam generated thereby, and a power generator connected to the gas turbine system and/or the steam turbine. In this IGCC plant, a combustion exhaust gas discharged from the heat recovery steam generator is desulfurized and exhausted into the atmosphere. In addition, an initial desulfurization equipment exclusively used for the early produced gas is provided for a flow path extending from an outlet side of the gasifier to a flare system.

摘要： Provided is a ground flare in which a low-frequency vibration generated from a ground flare tower, such as a chimney, is properly adjusted to suppress it below a fixture-vibration generation limit, thereby preventing surrounding objects from resonating and vibrating. In a ground flare that burns a flammable exhaust gas with a burner at the lower end of a chimney, in which the lower end of the chimney and the periphery of the burner are surrounded by a windbreak, the low-frequency-noise sound pressure level of a ground flare tower composed of the chimney and the windbreak is reduced by selecting at least one of changing a natural frequency generated from the ground flare tower, using multiple ground flare towers, and installing a low-frequency-vibration absorber in the ground flare tower.
