PROBLEM TO BE SOLVED: To obtain a clean gasificated fuel without using an expensive clean up device by separating a raw fuel including a heavy distillate to a light fuel and a residual including the heavy distillate by a distilling plant, making the light fuel to a fuel for a. turbine by gasificating and burning the residual in an exhaust gas boiler. SOLUTION: At the operation time of a plant, in ...

PROBLEM TO BE SOLVED: To improve reliability by multiplication. SOLUTION: A turbine controller 22 for each shaft has a sequential load controlling circuit 21 and an axial load controlling circuit 24. Each sequential load controlling circuit 21 outputs an axial load instruction signal (d) so that a sequential load returning signal (b) follows a sequential load setting signal (c). Each axial load co...

Methods of making cylindrical structures with cooling channels, such as, for example, combustor/transition pieces for gas turbines having a double wall with a plurality of cooling channels, both axially and, in some cases, circumferential cross-flow passages positioned between the structure's inner member and the outer member to provide cooling air thereto, are disclosed. The cooling channels are ...

A catheter capable of both sensing myocardial electrical activity and delivering ablating energy within myocardial tissue is disclosed. The catheter comprises electrodes on the outer sheath and contains a movable fiber optic cable that can be percutaneously advanced beyond the catheter body and into the myocardium for myocardial heating and coagulation, or modification of tissues responsible for c...

A catheter for delivering electrical energy to a selectable region of a patient's body has at least one layer of fibers with at least one electrically conductive fiber stranded over a flexible core. Each layer of fibers is stranded over the flexible core and underlying layers opposite in direction from that of the immediately preceding layer so as to provide a catheter with good torque transfer pr...

The innerliner ply of a tire has been modified in thickness to provide a profiled innerliner ply. A permeability relationship is established for the material of the innerliner that allows the average thickness of the innerliner ply to be adjusted based on its temperature. The maximum and minimum thickness are located in relation to the maximum and minimum internal temperature locations within the ...

Organic contaminants are removed from RPET flakes by a process that includes steam-stripping the contaminants out from the matrix of the RPET flakes. In an alternative embodiment, the RPET flakes are first comminuted to prepare RPET particles, and the RPET particles are thereafter steam-stripped.
