based boilers does not affect the pressure loss of the main steam/water flow through the boiler. This means that saturated steam leaving the steam drum has the same pressure as the feedwater entering the steam drum. The pressure loss of the evaporator has to be overcome using the driving force (natural circulation) or circulation pump (forced
