Alternative Energy Blog: Power Generation Improved Steam Temperature Control

Jim Cahill

Emerson’s Jeff Williams presented, Holistic Approach to Steam Temperature Control, at the 2018 Ovation Users’ Group Conference. Jeff opened describing the trend of plants being started and operated more frequently than in the past due to intermittent sources of renewable energy sources on the grid. A key challenge to this mode of operation is to maintain consistent superheat temperature in this transient environment…

Alternative Energy Blog: Reduce Boiler Tube Leaks with Better Steam Temperature Control

Jim Cahill

As the contribution of renewable energy sources grow on electrical power grids, so does the cycling its intermittency creates for power producers. This cycling affects steam used to drive the generators. For power stations where the electric generators are steam-driven, this steam is created by coal, nuclear, geothermal, solar thermal, waste incineration and sometimes natural gas. Boiler tube leaks caused by frequent…

Alternative Energy Blog: Real-Time Microgrid Control and Optimization at The University of Texas

Jim Cahill

At my alma mater, The University of Texas , here in Austin, Texas, is the Carl J. Eckhardt Combined Heating and Power (CHP) Complex . It is often described : …as the largest and most integrated microgrid in the U.S…. [It] is capable of generating 135 MW (megawatt) power (63 MW peak) and 1.2 million lb/hr (pounds per hour) of steam (300,000 peak). I mention all this because the microgrid controller is powered…

Alternative Energy Blog: Driving Turbine Generator Efficiency Improvements

Jim Cahill

A combination of more plentiful natural gas from shale formations, more global liquefied natural gas (LNG) facilities to transport it globally, and global political pressure to reduce carbon emissions has been shifting the mix of fuel sources for electrical power generation. Here in the U.S., natural gas has surpassed coal as the leading source of fuel, according to the U.S. Energy Information Administration . Natural…
