Specific fuel rate

Specific Fuel Rate (MMBtu/klb) Maximum Limit (klb/h)... 

You might think that the fed-batch technique would work in the single-reactant case considered above. A number of simulations were run, and results showed that there was little improvement when the base case kinetic parameters were used. The problem is illustrated in Figure 4.11. The material initially charged to the reactor is assumed to contain no reactant A (Ca = 0 at time = 0). The concentration of reactant has to buildup to quite high levels (Ca = 6 kmol/m3) because the specific reaction rate k is relatively small (4.045 x 10 4 s 1 at 340 K). Eventually there is enough fuel to cause a runaway. 

For Vulcan XC-72R, the specific corrosion rates (Areal m 2) at 1.0 V and 180 °C in H3PO4 were essentially independent ofheat-treatment temperature however, since the Tafel slopes decrease with increasing heat-treatment temperature, heat treatment affords increased life at the fuel-cell calhode operating potential (0.7 V). Little difference in either the Tafel slope or specific corrosion rate at 1.0 V was observed between as-received and heat-treated samples of Shawinigan acetylene black. 

Deposits were collected from the disengagment section and from the horizontal pass. A summary of properties for deposits removed from both locations appears in Table 3. Surface temperatures were controlled to about 500°C for probes in the disengagement zone. Specific deposition rates in the disengagment section are higher for the combustion tests than the gasification tests due to the higher fuel feed rate for gasification with the same total deposit mass. 

Improve performance of reversible stacks (capable of operating in both fuel cell and electrolysis modes) by reducing area specific resistance, rate of degradation, and seal leakage. 

Fuel-specific emission rates of elemental carbon are shown in Table 14.1. These rates can vary significantly as they depend strongly on the conditions under which combustion takes place. Woodbuming fireplaces and diesel automobiles are effective sources of EC per unit of fuel burned (Mulhbaier and Williams 1982 Brown et al. 1989 Dod et al. 1989 Mulhbaier and Cadle 1989 Hansen and Rosen 1990 Burtscher 1992). 

As a rule, the vaporized hydrogen escapes upwards, away from the site of release and from ignition sources, an advantage which, however, does not hold for confined or obstructed areas. The smaller the specific vaporization rate, the larger is the pool and the more extended and shallow is the evolved gas cloud. An LH2 pool exhibits a decrease in depth of 0.4 - 0.8 mm/s which is high compared with other liquid fuels [41].

The High-Temperature Gas-Cooled Reactor promises still further improvements in gas temperature, power density, fuel bumup lifetime, specific power rating, and conversion ratio. Several design features of this reactor concept generally favor the use of the Th /U fuel cycle over that of the cycle. Some of the more important reasons...
