摘要:
Synthesis gas (syngas) gasified in a gasification furnace to which coal is introduced burns in a combustor. An exhaust-heat recovery boiler generates steam by using exhaust gas let out from a gas turbine equipped with the combustor. The steam generated in the exhaust-heat recovery boiler is introduced to a steam turbine. A generator is driven by the steam turbine and the gas turbine to generate electrical power. Part of the exhaust gas let out from the gas turbine is introduced to a carbon-dioxide recovery unit, where carbon dioxide is recovered therefrom. Coal is carried to the gasification furnace by the carbon dioxide.

摘要:
A filter regeneration apparatus of a coal gasification system having a filter for capturing char (unburned matter) present in exhaust gas at an exhaust gas passage communicating with exhaust gas source including a coal gasification furnace, fills the filter container with inactive gas having oxygen concentration of less than 5 vol. % and heat the filter to a target temperature of 400 to 450° C. and feed ashing gas having oxygen concentration of 5 to 15 vol. %, thereby ashing char in the filter. This method and apparatus achieve ashing of char in a safe manner and shortens the time of regenerating the filter by controlling the oxygen concentration in the ashing gas and the filter temperature constantly to reach preset target values.
摘要:
An integrated gasification combined cycle that can adjust the balance of pressure/temperature in an overall plant and can stabilize the output of a gas turbine at an early stage during load variation, and an operation control method of the integrated gasification combined cycle are provided. When a calorific abnormality of fuel gas is detected during load variation of a gas turbine (5b), a load change command value of the gas turbine (5b) is set to zero or is decreased, and based on this load change command value, a power generation output command of the gas turbine (5b) is generated.

摘要:
A gasifier (101) including a fluid communication channel (131) that communicates a fluid, which undergoes heat exchange in the furnace, and that generates syngas by gasifying fuel; gas purifying equipment that removes impurities contained in the syngas generated by the gasifier (101); a gas turbine that is driven by the gas purified by the gas purifying equipment; and a heat exchanger that heats a fluid with exhaust expelled from the gas turbine. The fluid heated by the heat exchanger is supplied to the fluid communication channel (131) by being pressurized by pressurizing gas when performing warm-up of the gasifier (101).

A gasification system which ensures stable dust precipitation performance and which can achieve an increase in capacity is provided. In a coal gasification furnace having a coal gasification furnace configured to produce a gas fuel by gasification of a carbon-containing fuel, a cyclone which is provided downstream of the coal gasification furnace and which separates and removes char in the gas fuel, and a first filter and a second filter which are provided downstream of the cyclone and which precipitate char remaining in the gas fuel, the first and the second filters are disposed in parallel.
摘要:
A compact pressurized high-temperature gas cooler having superior heat exchange performance and excellent economical efficiency is provided. A return-flow structure is formed in which a flue through which high-temperature gas flows is formed in a pressure container, a heat exchanger is disposed in the flue, and a partition dividing the internal cross-sectional area of the flue is provided so that the high-temperature gas supplied from a bottom or a top portion of the pressure container flows back in a return direction. The cross-sectional-area division ratio dividing the internal cross-section of the flue is set so that the flow rate of the high-temperature gas flowing in one direction matches that flowing in the direction opposite thereto.
