Water Specification for low to medium pressure boiler

The feed water is sprayed into a stream of 5 psig steam for efficient heat transfer and subsequent oxygen removal. Return condensate is distributed on a tray to generate flash steam. The flash steam helps remove any residual oxygen in the condensate return, as well as the incoming boiler feed water.

Boiler Corrosion - Causes,Effects and How to Prevent it

pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.
