Foaming and priming in boilers - Lenntech

Priming is common cause of high levels of boiler water carryover These conditions often lead to super heater tube failures as well Priming is related to the viscosity of the water and its tendency to foam These properties are governed by alkalinity the presence of certain organic substances and by total salinity or TDS The degree of priming also depends on the design of the boiler and its steaming rate
