Fouling - deposition of ash on surfaces of boilers affects coal and biofuel powered power plants. Deposits reduce energy transfer from the combustion fuel to heated water and steam. In a typical base load boiler losses due to fouling top 5%, $25 million annually. Today there is no fouling sensing technology to direct cleaning of the boiler, driving up maintenance costs and inefficiencies. Our technology can directly measure the fouling buildup and create a close loop to optimize cleaning.
