equipment steam boiler fouling

ASSESSMENT OF ASH FOULING AND SLAGGING IN COAL …

fouling in coal-fired steam boilers are described in [4-8]. They are used to perform heat transfer analysis in the furnace and convection section using heat and material balances [1, 4-8]. For a given boiler, measured steam and water flow rates, flue gas and steam temperatures the cleanliness factors are varied until calculated and measured
