  • 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 ...

  • Frequency Converter energy savings on Boilers

    Boilers and heaters account for a significant share of a plant's purchased fuel cost. Combustion air fans are necessary to provide enough combustion air to the boiler or heater's burner system. Louvers, inlet guide vanes or frequency converters control the amount of air allowed into a boiler. Configuring a combustion air fan to allow the proper amount of air into the burner can improve boiler ...

  • How do we create an ethical grid?

    So much of what’s discussed in offices these days – and forever really – focuses on this: What’s best for the company? How do we increase profits? That’s totally understandable, given that a primary responsibility of any for-profit enterprise is to benefit its owners and investors. Still, as individuals, and I would argue, as part of the capitalist system, we have ...

  • Your electric meter: A villain or hero?

    Before energy became a hot topic, no one cared about the electric meter.  It was the box on the house we all ignored except the guy from the utility who dodged the barking dogs to take a reading from it once in awhile. It is a sign of our times that this box now inspires enough emotion for people to take to the streets. Protesters gathered outside the California Public Utilities Commission ...
