A train that generates only eleetrieity from the hot flue gas is ealled a Total Power Generation (TPG) train. A TPG train eonsists of a power reeovery expander, gear, generator, and sometimes a steam turbine (Figure 6-39). The valve arrangement for a TPG train requires speeial attention beeause the train operation and the proeess operation are independent. 

Production Tax Credit (PTC) for wind power producers. In addition, electric utilities are more and more likely to be required by local or national governments to use renewable, sources such as wind, for a significant portion of their total power generation. Consequently, many major utility firms and energy concerns have been investing significant amounts in new windmill farms. 

Here on we continue the solution process in terms of Eq. (2.53). The problem is symmetric with respect to the midplane, and the temperature distribution should be made of even functions. This fact makes Ci 0. The same result follows also from insertion of Eq. (2.53) into Eq. (2.49). The total power generated within the plate is transferred from its surfaces to the ambient,... 

Not only can a poorly tuned probe cause ineffective sample excitation and inefficient signal detection, but it can also cause damage. If only a portion of the total power generated makes it into the sample (forward power), the remaining power (reflected power) must be dissipated somewhere else. In some cases, a poorly tuned probe can reflect enough power to damage the NMR hardware, especially in high power applications such as solid-state NMR (not covered in this book). 

Steam flows at 2.5 kg/s through a turbine, generating electricity at the rate of 1 MW. The inlet velocity of the steam is 100 m/s and the outlet velocity is 30 m/s the inlet is located 30 m above the outlet. Of the total power generated, estimate the fraction contributed by the change in kinetic energy of the steam and the fraction contributed by the change in potential energy. 

More recently, power generation cost for the MSR and a pressurized water reactor (PWR) was re-evaluated at the LLNL [XXX-20], using the original evaluation by the ORNL [XXX-2, XXX-19], To make a fair comparison, a 1 GW(e) plant size was assumed for both plants. Five cost components were considered, including capital cost, O M cost, fuel cost, waste disposal cost, and decommissioning cost. Assuming the capacity factor of the MSR as 90% and 80% for the PWR, the results are shown in Table XXX-3 the conclusion is that the MSR could be 20% to 25% cheaper than the PWR in total power generation cost. 

The total heat generation is the difference between the total power generation in the fuel cell at reversible condition (no losses) and electrical power generated at operation conditions with losses and this is the defined by the following equation ... 

An IGCC plant generally produces fewer water effluents than a conventional coal-fired power plant does. The amount of process water blowdown is about the same for both gasification and direct coal combustion. However, the steam cycle in IGCC power plants produces much smaller amounts of wastewater blowdown because less than 40% of the total power generated comes from the steam cycle.
