Figure 4-70 shows a four-body TPG train (string). As before, the expander supplies power to the generator. The steam turbine supplies power to the generator, provides startup power, and provides control for synchronization. The generator provides electricity, and the gear is used to allow the expander and steam turbine to operate at near optimum efficiency with the generator at its desired speed. 

Why the motor In Treblinka there was certainly an electrical plant, since the camp was not connected to the local power supply. The generator of such a plant was customarily driven by a diesel motor. Since the exhaust fumes of such machinery have an atrocious odor, Wiemik, a layman with respect to the technical facts, obviously believed they made a suitable instrument for murder. After the Red Army had gained control over the area around Treblinka in August 1944, a Soviet investigatory commission quickly got to work and determined that in Treblinka three million people had been killed. However, neither steam nor gas were now named as the method of murder, but instead suffocation by means of chambers which were vacuum-pumped 59... 

At BASF, flammable solid, pastelike, and liquid residues are combusted in eight furnaces. Each combustion unit consists of a rotary kiln with afterburner chamber and a steam boiler. The superheated 18-bar steam from units 1 to 6 is fed into the BASF plant network. In units 7 and 8, a higher-value steam is generated with an efficiency of ca. 74 % and supplied to a back-pressure turbine, where it is expanded from 43 bar to 5 bar. To utilize the heat of the flue gases between 300 C and 180 C, a waste-heat boiler was installed to raise 5-bar steam. Electric power and 5-bar steam are fed into the respective plant systems (Fig. 113). 

The second heat removal system is an independent cooling system (ICS), which includes, besides a part of primary and secondary circuit equipment, a loop separator-cooling condenser with natural circulation. Via this loop the heat is removed to the intermediate circuit water. This system ensures independent (from the turbine generator systems) reactor cooling and independent reactor plant operation at a constant power level up to 6 % N om at the nominal steam pressure. In case of total RI de-energizig the system ensures cooling of the reactor over several days. Connection/disconnection of ICS is realized with no operator action and without using external power supply systems. 

For electrical power generation based on an integrated concept, the efficiency can be as high as 25-30 %, comparing the power supply to the furnace with the power generated in the steam turbine. In addition to electrical power generation, a possible efficiency of around 100 % has been attained for production of process steam or district heating. Several ferrosilicon plants in Norway (six) and... 

With the ejcoaption of the steam-tur primary loop pumps, moat equipment for normal operation of the reactor and its cooling system is el trf.c 5illy powered. This power Is supplied by two Independent systems, the 23C kilovolt Hartford Utility Power Lo .-)p luiii tue 13 0 KV turbine generat in the local power house. The 23O kilovolt auppl y is transformed to 13,3 kilovolts for the largest loads such as the river pump motors, then further stepped down to hl60 volts and lower for other loads. Local power is generated at the 13,8 kilovolt level. 

A methanol fuel processor based on steam reforming in a fixed catalyst bed and membrane separation was described by LedjefF-Hey et al. [401]. The system consisted of an evaporator, a steam reformer, which was supplied with heat by a catalytic burner, and a membrane separation module, which carried membranes of a very high thickness of 7.5 mm. At 5-bar system pressure and S/C ratio of 2.0, a hydrogen flow equivalent to 1.1-kW thermal power was generated by the system, which had an overall efficiency of 54%. Between 40 and 62% of the hydrogen produced by the reformer could be separated by the membrane module. Leakages in the sealing of the membrane module led to carbon monoxide spill-over to the permeate, but this was limited to carbon monoxide concentrations well below 100 ppm. 

The HGP, owned by the Supply System, received steam via the steam piping system from the N Reactor. The HGP consists of two 430-MW (electrical) low-pressure turbine generator systems with associated auxiliary equipment normally found in a steam power station. The HGP is operated by the Supply System. The HGP condensers and auxiliary cooling systems were supplied by raw water pumped from the Columbia River and discharged back to the river approximately 90 m (300 ft) upstream from the N Reactor raw water intake structure. 

The envelope defined by A, B, C, and D in Fig. 6.70 represents the most thermally optimized use of a gas turbine in a cogeneration application (i.e., provides the lowest FCP). Operation along the line CE, DF, or any intermediate point to the left of line CD represents the nse of condensing steam turbine power generation with the E and F points appUcable for combined-cycle operation without any heat supplied to process.Thus, the cycles along line EF are combined cycles providing power alone.
