  • Optimal maximum continuous operating load of fuel fired steam–based generating units

    This paper establishes the optimal maximum continuous operating load of fuel fired steam based thermal units without endangering the operation, asset life or carbon footprint. The interconnectivity between unit loadability and energy efficiency (represented by heat rate) enables the unit to be loaded to as high as 10% over and above the 100% maximum continuous rating (MCR) provided the energy ...

  • Tuning Your Boiler for Fuel Savings – Out with the Old in with the New Technology

    The USA has about 811,000 MW of installed generation and over 52% of our Electric power is produced by aging coal fired power plants. The average utility boiler furnace was designed about 30-40 years ago. According to DOE records, the average boiler in 1974 was fired with 80% bituminous coal. Now, western PRB coal is much more prevalent and represents about 50% of total coal ...

  • Solar fuels: how planes and cars could be powered by the sun

    Solar energy is the world’s most plentiful and ubiquitous energy source, and researchers around the world are pursuing ways to convert sunlight into a useful form. Most people are aware of solar photovoltaics that generate electricity and solar panels that produce hot water. But there is another thrust of solar research: turning sunlight into liquid fuels. Research in solar-derived liquid ...
