Reaction Engineering International (Murray, UT) will design, prototype, and demonstrate a monitoring system for boiler condition management. The key objectives are to miniaturize the design; combine quantitative heat flux, deposition rate, relative surface temperature, and metal wastage measurements into a single sensor; and integrate monitoring output with a plant distributed control system (DCS). The project will culminate with a demonstration and characterization of corrosion, deposition, heat flux, and temperature at multiple locations within a full-scale pulverized coal-fired power plant.
