The backflow of DPM mentioned earlier can be more clearly seen in Fig. 9, showing it flowed to the roof level at the intersection and face area upstream of face 2.

From any instant of the initial and final time (t and t final) during thermal loading operation of the reservoir, the temperature profiles obtained T z,t) and its T min reference temperature permitted between the points analyzed are possible to determine the available transiently energy stored.
Based on this study, it was concluded that the short push and curved pull tubing system was the best design of all four designs, and effectively ventilated the face area during the truck loading operation.
At this point, according to Schwoebel, Miceli interjected and said, "This kind of thing can't be duplicated during the actual loading operation.
Therewith, the hydrogen crossover was reduced and the current efficiency during partial load operation was increased.
This combustion mode offers the possibility to reduce emissions and fuel consumption during part load operation.
Furthermore, a special burst mode is added to reduce the power consumption during light-load operation.
The results show that the performance of hybrid system during part-load operation varies significantly with different control methods.
