The carburizing/nitriding furnace may be divided into a plurality of zones, each of which is provided with control means for controlling the carburizing/nitriding atmosphere and carburizing/nitriding temperature in the zone. The continuous annealing line may further comprise a plurality of carburizing/nitriding furnaces and have an arrangement for conducting a switching between a mode in which the carburizing/nitriding furnace is used for carburizing/nitriding the steel strip and a mode in which the carburizing/cooling furnace is used for cooling the steel strip.

摘要： The present invention provides a method for suppressing power fluctuation of a high-efficiency combined power generation system that uses a byproduct gas generated in a plant, the method including the steps of adding a high-calorific-value substance having a calorific value higher than that of the byproduct gas so as to increase both the total calorie per unit of time and the calorific value per unit gas quantity up to predetermined targets; and adding a low-calorific-value substance having a calorific value lower than that of the byproduct gas so as to control the caloric value and/or the composition of the power generation fuel, whereby the total calorie and the calorific value are controlled within predetermined ranges. The present invention also provides another method for suppressing power fluctuation of a high-efficiency combined power generation system that uses a byproduct gas generated in a plant, the method including a step of alternately switching charge/discharge modes of at least two storage apparatuses to suppress the fluctuation of the power generated, and a power generating facility for these methods. According to the present invention, not only short-term power fluctuation caused inside the plant but also long-term fluctuation are also suppressed. The excess power, whose fluctuation is suppressed, can be controlled to have a power supply pattern coincident with a power demand pattern so that power can be stably supplied to a site outside the plant.

摘要： A heat exchanger filled with a catalyst used for reforming DME is provided in an exhaust system of a combustion apparatus such as a furnace, an internal combustion engine, or electric power generation equipment. A mixed gas of DME and H2O is fed to the heat exchanger, thereby pyrolyzing the DME and recovering the sensible heat of an exhaust gas of the furnace or the internal combustion engine as H2 fuel. Since the waste heat is recovered not as steam, hot water, heated air, or the like, but as H2 fuel or H2 and CO fuel, the application of the recovered energy is not limited.
