The aim should be that the pressure drops between each boiler outlet and the header off-take to the plant should be within 0.1 bar. This will minimise carryover and help to prevent overload and lockout of boilers. The layout shown in Figure 3.8.2 shows an improved design of a new header.Get Price
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 Get Price
Operating the boiler at pressures significantly lower than design pressures is a cause of carryover. Lower the steam pressure more will be the specific volume of the steam inside. Hence, the steam velocity in drum internals would be more at lower pressures. This will hamper the separation of water droplets from steam which results in carryover. 2.Get Price
