Abstract
The build up of ash in a pulverized coal-fired boiler 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.
