MR. MEGAWATT pressure. This points to some problem with condenser efficiency. her face and water all around her feet. I realized I might end up Based on this graph we thought we were on the right path. But sleeping with the fishes after all. ~ before we did our victory dance, we wanted to know if this discrepancy could explain all the difference in generation and Mr. Megawatt is Frank Todd, manager of Thermal Performance the cause of the problem. Figure 6 shows the plant generation for True North Consulting. True North serves the power industry corrected for the influence of the expected condenser pressure, in the areas of testing, training and plant analysis. Todd’s career, and for the actual condenser pressure. The green line is the difspanning more than 30 years in the power generation industry, has been centered on optimization, efficiency and overall Thermal ference between the two, which is the loss due to the condenser Performance of power generation facilities.

Giuseppe was impressed, but we noticed the big guy outside the conference room door was not budging. “So,” Giuseppe said, “yuz told us the ® tomato is bad, but not why the tomato is bad or how we make sauce with the bad tomato. Mr. Gangone, my uncle, would be pleased to know how we fix dis’ problem.” Looking at Brian, I noticed little beads of sweat running down his forehead and knew we had to come up with something TRY quickly. Then I remembered that when I BEFORE was looking at the data I had noticed the YOU BUY! temperature rise across the condenser was a little fishy and I said, “mackerels in the waterbox! 800.536.0790 “Look at this graph (Figure 7),” I continued. “You see the temperature rise across 90° Prism & the condenser is increasing.
