Figure 2.10 and 2.11 shows the simulation results acquired, with Figure 2.10 for the fuel water contents expressed in cold gas efficiency (left Y, based on HHV) and C and H conversions (right Y) and Figure 2.11 for the necessary conditions including the circulation rate of heat carrier particles (left Y) and the amount of auxiliary fuel fed to the combustor (right Y). The displayed circulation rate in Figure 2.11(left Y) refers to the specific value over the treated dry fuel amount, while the auxiliary fuel feed amount (right Y) indicates the value without heat loss from the system. As anticipated, the available cold gas efficiency and C and H conversions (Figure 2.10) all decrease with raising the water content in the fuel. The higher the fuel water content, the more the heat required to vaporize the water and to heat the resulting steam to the gasifier temperature (here 1073 K). …show more content…
This outlet temperature is necessarily kept until the downstream scrubber to avoid the possibly substantial deposition of tars on the involved pipeline. Hence, the higher water content means the more C needed to be combusted to maintain the temperature of the combustor as well as of the fuel gasifier, lowering consequently the C amount for gas production. The converted H also decreases because the decreased C amount for steam gasification reduces the converted H from H2O (i.e. steam). Corresponding to the simulation conditions that 99% of the tars is reformed and the combusted char is almost free of H, the resulting H conversion is always higher than 100%. When no heat loss is considered, the available cold gas efficiency can be over 80% for fuels with water content lower than 40 wt. %. In order to reach a cold gas efficiency of 85%, the fuel’s water content has to be lower than 10 wt.

Figure 1: Kneelers Figure 2: A physically challenged child using Kneeler 2. Tools with Velcro Straps Tools with velcro straps was designed fixing Velcro straps to standard hand tools for easy handling and to get grip. Depending on the tool and how it is used, two straps was usually used. Terrycloth…

Unit 2 Lab Assignment The two different types of ground cover are dark volcanic rock and sand. They are so different not only because of the texture but the pure color of them is contrasting. The volcanic rock darkened as it cooled many years ago. A predator is any organism that actively hunts for its food, or prey. In the video, the rock pocket mouse is the prey while birds are the predators. The mouse is referred to as the “snicker bar of the desert” in the video. Typically, the rock pocket…

In the experiments I conducted, I concluded that the mathematical relationship between frequency and time period is inverse. When looking at my data, I noticed that as the time period increased, the frequency would decrease. An example of the inverse relation can be seen in each one of my data tables, but I will show one example from Part B of my experiment. For 33.5 centimeters, the time period was roughly 1.15 seconds and the average frequency was 0.87 Hz and at 49 centimeters the time period was…

Single units’ activity are marked with red dots. Figure 2. Design of ANC experimental procedure. The activity of the axonal tract is recorded by a suction electrode (labeled in blue in A) and its output is shown in black traces on the two panels (B) that display the results of the orthodromic…

nitrite when the number of chewings is increased and as opposed to the hypothesis a curve that levels off but one that appear linear in the investigated range. The various trials lie within the range of each other’s uncertainties as shown in tables 2 and 3. This suggests that the results have a very high precision, which in turn indicates that the random errors that occurred during the various experiments will have had a minor effect. Since it wasn’t possible to find a literature value to compare…

Nt1310 Unit 2 Circuit Lab

The purpose of the second circuits lab was to investigate voltage, current and resistance of a circuit in series, a circuit in parallel and a circuit that cannot be classified as either. Once again voltage (V) is the electric potential difference measured in volts. Resistance (R) is how much the electric force is reduced measured in Ohms. And current (i) is the flow of electrons measured in Amperes. In the circuit in series, the current is constant throughout since there is only one past for the…
