The operating objectives for steam boiler plant include: Safe operation. Maximum combustion and heat transfer efficiency. Minimum maintenance. Long working life. The quality of the water used to produce the steam in the boiler will have a profound effect on meeting these objectives. There is a need for the boiler to operate under the following
Steam purity should not be confused with steam quality. Steam quality is a measure of the amount of moisture in the steam. It is expressed as the weight of dry steam in a mixture of steam and water droplets. For example, steam of 99% quality contains 1% liquid water. Carryover is any solid, liquid, or vaporous contaminant that leaves a boiler
May 09, 2016 · The steam purity is defined by the quality of the condensate produced by the generator, which is referenced to the US Pharmacopoeia standard for Purified Water (PW). Pure steam is produced in a dedicated boiler similar to that required for clean steam, but the quality standard for the condensate produced by this system is referenced to the US Pharmacopoeia standard for Water for Injection (WFI). Water for Injection is a higher standard of purity than Purified Water.
