The mixture of ammonia and water enters the heat recovery unit before the vapor generator. A concentrated vapor of ammonia is generated in the vapor generator at high pressure and temperature. • The concentrated vapor is then sent to a superheater, where the temperature of ammonia vapor is ...
A schematic view of interdigital electrodes with a backside heater. 5.1.3.1.1 Semiconducting resistive hydrogen sensors Semiconducting metal oxides (SMOX) have been the pioneer semiconducting materials for resistive gas sensors with their special electron configurations partially occupied d shells since ...
The intensity drops at wavelengths of ≈6 µm and higher, corresponding to residual humidity, i.e., IR absorption caused by water vapor in air. Thermal characterization of the IR emitters showed significant differences in the temperature of the suspended parts of the filament and the parts ...

bypass valve to the regeneration gas heater. The gas outlet temperature is controlled to 570–600 °F. The hot gas flows upward through the dehydrator being regenerated and heats up the bed to a temperature at which the water content of the molecular sieve is reduced to the required low ...
apply a high voltage across the lamp terminals when the lamp is switched on and the electrodes are cold. The high voltage results in increased “sputtering” of material from the electrodes, with a consequent reduction in lamp life, but gain in efficiency due to the absence of a heater ...
A temperature controller 66 creates a signal that is amplified through a power amplifier or modulator 336 and applied via an electrical connection 70 to a resistive heater terminal 320 (FIG. 27A), which is coupled to a resistive heater 72 embedded in ESC 6. A coolant temperature and flow ...
Hot gas leaving the isobutane superheater 211 is passed through the liquid heater and boiler 212. The heated isobutane from the liquid heater and boiler 212 can be used to drive a high pressure vapor turbine shown at 215. The high pressure turbine can be used to drive an electrical ...
