摘要： This invention aims at providing a method of continuously carburizing a metal strip, which is capable of providing industrially optimum carburization conditions while attaining non-soot-generating atmospheric data, desired carburization concentration distribution and desired carburization rate, in a case where a strip passed through a carburization furnace is carburized continuously in a surface reaction rate-governing area in which the carbon concentration in a superficial layer of the strip has not yet reached an equilibruim level with respect to the time. The method consist of carburization concentration distribution (S7), on the basis of the carburization conditions including given specification data for the steel plate, furnace temperature and composition of the atmospheric gas, outputting the concentration of the components of the atmospheric gas, feed and discharge rates and other carburization conditions when the set carburization rate and an actual carburization rate are equal (S8-S15), and correcting the set carburization rate when a difference between the set carburization rate and an actual carburization rate is large, and correcting the strip feed rate while correcting the composition of the atmospheric gas when a difference between the predetermined carburization rate and set carburization rate is large (S9).

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 regenerative atmosphere-gas heating system includes at least three regenerative heaters. Each of these regenerative heaters successively cycles through a combustion state, an atmosphere gas heating state and an atmosphere gas sucking state. As a result, the atmosphere gas can be recovered for reuse and the developed heat of the recovered atmosphere gas can be converted into developed heat of the combustion air for an improvement in thermal efficiency.

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.
