  • Steam Headers and Off Takes

    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.
