Sep 29, 2014 · Effect of silica in boiler feedwater • Silica in boiler feed water alters the steam velocities and the pressure drops, reducing the capacity and efficiency of turbine • Any minor deviations of silica concentrations in a power plant can have serious and expensive consequences in relation to performance, reliability, efficiency and safety Get Price
Silica must be held to exceptionally low levels in high-pressure boilers to prevent carryover into steam and deposition on turbine blades. In addition, ammonia or neutralizing amines may be applied to neutralize CO2, an acidic byproduct that promotes corrosion.Get Price
The SNCR system is installed in the first boiler pass above the furnace and is therefore part of the boiler. The essential fulfillment criterion for the operation of an SNCR process is the supply of the reagent ammonia or urea at the required flue gas temperature (between 850 and 1050 ° C) and the cross section of the first boiler pass.Get Price
