摘要： PURPOSE:To reduce the amount of leakage to the rear side of a second sidewall for reducing the load on a driver for capacity adjustment by a method wherein the inner circumferential part of the second sidewall is extended in the axial direction of a turbine impeller to form an L-shaped axial section, and an intermediate pressure chamber is formed between the second sidewall and an annular side plate. CONSTITUTION:P represents the pressure in an intermediate pressure chamber 9, P1 the pressure at the inlet of an entrance flow path 8, and P2 the pressure at the outlet. The pressure P varies depending upon the sizes of gaps at the inner and outer circumferences of a second sidewall 3 and a gap at the inner circumference of a slot 6, however, a relationship P1>P>P2 is established. As the second sidewall 3 having an L-shaped axial section is provided to form an intermediate pressure chamber 9, a thrust F= A(P1-P) is exerted on the second sidewall 3, where A is a sectional area perpendicular to the axial direction. By adequately adjusting the gaps, P=1/2(P1+P2) is established. The inner circumference of the second sidewall 3 serves as a weir, the differential pressure across the second sidewall 3 becomes small, resulting in an reduction of gas leakage amount to the rear side of the second sidewall 3.

摘要： PURPOSE:To precisely control nozzle intervals by sending driving signals to a driving source from a driving signal generator based on the necessary moving quantity and a new driving direction upon operating the necessary moving quantity for a nozzle side plate and deciding the new driving direction. CONSTITUTION:A present position of a nozzle side plate 3 and a driving direction of the nozzle side plate 3 theretofore are always stored by an electronic computer 11. Simultaneously therewith, when a new set position is inputted to the electronic computer 11, a necessary moving quantity of the nozzle side plate 3 is operated as a difference between the present position and the set position. Next, a new driving direction is decided from magnitude relationship between the present position and the set position. When the new driving direction and the last driving direction are different to each other, a predetermined correction quantity is added to the necessary moving quantity. Driving signals are sent to a driving source 8 from a driving signal generator based on these necessary moving quantity and the new driving direction. It becomes possible thereby to correctly set position of the nozzle side plate 3 and to precisely control nozzle intervals.

摘要： PURPOSE:To perform a precooling operation based on a turbine expansion mechanism in a short time as much as possible, while preventing overload operation of a turbine type expansion mechanism on both high temperature side and a low temperature side. CONSTITUTION:Based on an inlet pressure P2 of a low temperature turbine and inlet temperatures T1 and T2 of each turbine, opening control of a turbine inlet valve 15 on a high temperature turbine inlet side is carried out. A low temperature turbine inlet temperature setting means 31 sets a limit value P2 set for the low temperature turbine inlet pressure P2 based on the high temperature turbine inlet temperature T1. A first valve opening arithmetic operation means 32a computes a first valve opening Va based on the pressure limit valve P2 set while a second valve opening arithmetic operation means 32b computes a second valve opening Vb based on a temperature ratio T1/T2. A turbine inlet valve opening control means 33 controls the opening of the turbine inlet valve 15 based on a lower side valve opening Va (or Vb).

摘要： PURPOSE:To enhance CO purity by treating gas containing CO in the processes of temperature rise, adsorption, pressure reduction, washing and desorption respectively, dividing the desorption process into a preliminary desorption process and a longer main desorption process to recover CO and overlapping the main desorption process in two adsorption columns. CONSTITUTION:Raw material gas containing CO is pressurized by a compressor 10 and fed to an adsorption column A for carrying out the temperature rise process, and then CO is adsorbed by an adsorbent to which a Cu component is annexed and non-adsorbent components such as N2 and the like are discharged from a tube 2 into the outer air. The adsorption column A is connected with an adsorption column B, reduced in pressure and washed with CO gas from a product gas storage tank 6. After that, the pressure of the same is reduced by a small vacuum pump 70 down to atmospheric pressure or lower, followed by preliminary desorption, and its pressure is further reduced by a vacuum pump 50 for a time longer than the preliminary desorption. Then, water desorption process is carried out and the desorption gas is recovered as product gas. The main desorption process is partially overlapped in the beginning process in a adsorption column D and in the final stage in an adsorption column C.
