  • Furnace wall ash monitoring system
    Patent number: 4571094
    Abstract: The build up of ash in a pulverized coal-fired boiler and other similar ash producing combustion operations is achieved by comparing the heat flux simultaneously detected by a first flux detector which is maintained free of deposits and a second flux detector on which deposits are permitted to form. The net values from the heat flux comparison is proportional to the heat flux which is not reaching the boiler walls as a result of the ash deposits.
    Type: Grant
    Filed: November 7, 1983
    Date of Patent: February 18, 1986
    Assignee: University of Waterloo
    Inventors: John R. Wynnyckyj, Edward Rhodes, Allan K. Chambers
