Deploy a Dedicated Low Pressure Air Compressor. Often because the large horsepower high pressure compressors cannot easily be shut off and also have to run the low pressure (100 psig) plant, service and instrument air is taken from the high pressure receiver that is regulated down to the low pressure.

Instead of using high-pressure steam from the main boiler, the low-pressure steam generated in the biomass boiler is used to meet the process demands of the coal-fired power plant. Parallel co-firing offers more opportunity for higher percentages of biomass fuels to be used in the boiler. This technology also offers lower operational risk and
