Cooling configuration

The coolant flowrate for this case is 11.1 kg/s. This should be compared with the coolant flowrate required in the jacket-cooled configuration of 25.8 kg/s, which is over twice as much. 

This mechanical refrigeration system can be automatically reconfigured to operate in any of the four modes including the three free cooling configurations, which are listed in Table 2.14.

Figure 8-5 shows the different cooling configurations used to study the thermal conductivity along and across the stack. The electrical load and UU curves were measured using a battery test system. The voltage of each cell was monitored separately. Figure 8-6 shows a typical C///curve for the stack. Five fuel cell stacks were used for the experiments described here. 

Figure 8-5. Cooling configurations used to develop the fuel cell stack thermal model Top and bottom means, the cooling plates are mounted parallel to the both end plates of the stack. Lateral cooling means, the cooling plates are mounted perpendicular to the cells, contacting all the cells.)...

A methanation section consisting of three adiabatic reactors is used to simulate the fixed bed with the intermediate cooling configuration (reactors 11, 13, 15, see Figures 8.4 and 8.5). 

The FBNR uses TRISO particles within SiC-coated spherical fuel elements in an up-flow coolant stream, which, if interrupted, allows the particles to relocate into a subcritical, well-cooled configuration. 

Shellac. Shellac wheels are limited to a few appHcations where extreme coolness of cut is required and wheel life is immaterial. They are produced by mixing shellac [9000-59-3] and abrasive grain in a heated mixer, then rolling or shaping to the desired configuration.

Other wet high intensity units provide configurations that have rotating matrixes similar to wet dmm units having cooled electro cods. StiU others fad. into the category of filters using cryogenicady cooled cods and stationary matrixes (Eig. 10).
