Power Boiler - Power BoilerBoiler pressure is the key factor for determining the need for a condensate polishing system. With a steam generator plant with low steam pressures (below 40 kg/cm2 ), the requirement of the CPU is usually avoided. Hard scale formation and boiler metal corrosion can easily be prevented through FW treatment before sending to the boiler proper.Power Boiler - Information5/5/2015 · Two types of AVT are; i) AVT (R) Using Ammonia (NH3) and as reducing agent like Hydrazine (N 2 H 4), ii) AVT (O) same as AVT ® minus reducing agent i.e. N 2 H 4.

For most dissolved solids found in boiler water, it is negligible by comparison to mechanical carryover at pressures less than 2000 psig (13.8 MPa). An exception is silica for which vaporous carryover can be substantial at lower pressures. Vaporous carryover depends on pressure and on boiler water chemistry.
