As the boiler pressures increase above 400 psi, there is an increase in the tendency for silica to be selectively carried into the steam in amounts proportionate to the amount of silica present in the boiler water. Problems caused by carryover. Suspended and dissolved solids in the boiler water tend to deposit in the steam and condensate system.
