There can be many different cycle configurations for the hybrid fuel cell/turbine plant. In the topping mode described above, the fuel cell serves as the combustor for the gas turbine, while the gas turbine is the balance of plant for the fuel cell, with some generation. In the bottoming mode, the fuel cell uses the gas turbine exhaust as air supply, while the gas turbine is the balance of plant. In indirect systems, high-temperature heat exchangers are used. 

The answers are rate of heat added in the low-temperature heat exchanger = 125.6 kW, rate of heat added in the high-temperature heat exchanger = 2501 kW, net power produced by the Rankine cycle = 357 kW, and efficiency of the solar heat engine = 357/(125.6-I-2501)= 13.59%. 

The Advanced Zero Emission Power (AZEP) concept replaces the traditional combustor with a more complex and highly integrated unit, consisting of a combustor, an air preheater, a membrane section and a high-temperature heat exchanger section. 

Long life, high effectiveness, high temperature heat exchangers for process flow heat recovery subsystems for high system efficiency. 

The reactor for the MHR-T RP is designed on the basis of the GT-MHR reactor concept. The main reactor equipment is arranged in a vertical vessel located parallel to the power conversion unit and high-temperature heat exchanger vessels in a separate cavity. 

The closed gas turbine cycle is shown in Fig. 5.2-9. Closed cycles are typically used in nuclear power plants, where the heating fluid in the high-temperature heat exchanger...

The presence of a deposit on the "cold side" of high temperature heat exchangers such as might be found in steam raising plant, may give rise to high metal temperatures that can increase corrosion or even loss of integrity of the metal with costly consequences. 

C/C-SiC tubes for high temperature heat exchangers in coal combustion chambers could withstand highly aggressive environments including water vapour and liquid coal slags, especially coated with multilayer EBC based on B4C, SiC and Cordierite. 

The next synthesis step involves task integration, that is, the combination of operations into process units. In one task integration, shown in Figure 4.20, reactor effluent is quenched rapidly to 1,150 F, primarily to avoid the need for a costly high-temperature heat exchanger, and is sent to a feed/product heat exchanger. There, it is cooled as it heats the mixture of feed and recycle chemicals to 1,(X)0°F. The stream is cooled further to 100°F, the temperature of the flash separator. The liquid from the quench is the product of the reactor section, yet a portion of it is...
