A two-stage screw compressor has a low-pressure stage screw compressor and a high-pressure stage screw compressor integrally constructed. Compression space is formed by a male rotor and a female rotor, and operation gas is fed for compression to the compression space. A method of supplying lubrication oil prevents degradation of volumetric efficiency caused by return of lubrication oil, coming from a bearing and a shaft sealing device, to the low-pressure stage screw compressor. As a result, refrigeration capacity is improved and the amount of the lubrication oil is reduced.

A hydrogen iodide manufacturing method which includes a step of producing aqueous solution of hydrogen iodide and sulfuric acid by causing iodine-containing aqueous solution and sulfur dioxide to react with each other in a pressurized condition. The pressurized condition may be of not lower than 0.1 MPa in gauge pressure. The method may further include: a separation step of adding iodine to the aqueous solution of hydrogen iodide and separating an upper phase containing sulfuric acid relatively to a large extent and a lower phase containing hydrogen iodide relatively to a large extent; and a step of producing hydrogen iodide by adding sulfur dioxide to the upper phase in a pressurized condition and extracting the produced hydrogen iodide to the lower phase.

A fuel reforming method includes the step of supplying carbon-containing fuel and steam to a reactor filled with a fuel reforming catalyst and a CO2 absorbent and discharging CO2, and setting the absorbent at an absorption temperature, thereby converting the carbon-containing fuel into reformed fuel, and separating CO2 from the reformed fuel, the step of obtaining a product gas by oxidizing a portion of the reformed fuel and/or the carbon-containing fuel with an oxidizer, and heating the absorbent with this product gas to a regeneration temperature, thereby regenerating the absorbent and storing heat in this absorbent, and the step of supplying the carbon-containing fuel and steam to the reactor, thereby cooling, to the absorption temperature, the absorbent heated to the regeneration temperature, and converting the carbon-containing fuel into reformed fuel by heat energy stored in the CO2 absorbent. An apparatus for the method is also disclosed.

A controller includes a program for controlling a group of boilers having boilers with a plurality of staged combustion positions. The program is arranged to control the boilers and the combustion positions such that a total load following evaporation amount obtained by summing up load following evaporation amounts of the respective boilers comprising the group of boilers becomes equal to or more than a setup load following evaporation amount which is an evaporation amount that the group of boilers is to follow.
