contactA low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure.
contactBoiler 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.
contact201555 · It is necessary to treat the boiler water to produce protective coat on the tubes required for good quality water & steam. For this it is necessary that the water shall be low controlled alkaline, very low level of dissolved Oxygen and very low presence of ions like Cl–. Silica from CW is another damaging factor as it deposits on turbine.
