A regenerative turbomachine has a rotatable bladed impeller (1) and an annular housing (3) surrounds the impeller (1) and defines a topological flow channel for a working fluid. There is also an inlet port (4) for admitting a working fluid to the housing (3) and an outlet port (5) spaced circumferentially of the impeller (1) from the inlet port (4) by which the working fluid can leave the housing ...

A multistage centrifugal compressor has a shaft (1) rotatable on an axis and a plurality of centrifugal impellers (4a-d) fixed on said shaft and having outlets at their peripheries. Conduits connect the impellers to form a path for fluid undergoing multi-stage compression by said impellers from a suction side to a delivery side. The conduits including a plurality of diffusers (8a-d) arranged radia...

The process for regulating the firing power in combustion plants, in particular in refuse combustion plants, in which process the measured O2-moist content of the flue gas is used as higher-order set point controlled variable for regulating the fuel supply and the measured steam flow rate as lower-order set point controlled variable (10) for regulating the primary air supply, provides, in accordan...

For the purpose of regulating the furnace output of incineration plants with a combustion grate, the primary air supply is variously regulated by zones along the length of the grate as well as in the transverse direction of the combustion grate. A monitoring device in the form of a video camera, which monitors the different burning behavior in the individual combustion zones, serves this purpose. ...

PURPOSE:To eliminate a scattering of temperature within a room and make an entire comfortable interior space by a method wherein a distribution of an interior temperature is detected by an infrared rays sensing means and in case of cooling operation, for example, air blowing is carried out preferentially to a hot part and in turn in case of heating operation, the blown air is fed to a low temperat...

A refrigerating machine including an evaporator section, absorber section, condenser section and a regenerator section respectively divided into two stages. The first evaporator stage and second evaporator stage are arranged so as to be enclosed by the first absorber stage and the second absorber stage, with the first absorber stage being combined with the first evaporator stage and the second abs...
