The paper presents the results of a unique method of ash measurement at the NRG Huntley station. High Temperature strain gauges were installed in the boiler penthouse. The gauges were located on rods that support the superheater pendants. Output from the gages measure ash accumulation and soot blower effectiveness. Output from the system is utilized in the soot blower control system to optimize blower operation. The system will allow less steam to be used for soot blowing while keeping the superheater clean at all times. This is valuable to the plant as a switch to 100% PRB coal is made. The paper will present details of the installation.
