Abstract

An evaporator system (200) comprises an evaporator (202); a drum (204); and a pump (206) that are in fluid communication with each other. The pump (206) is operative to create a temporary pressure gradient during start-up of an evaporator system (200) and transport a fluid from the evaporator to the drum prior to the fluid reaching its boiling point in the evaporator (202). Following the fluid reaching its boiling point in the evaporator (202), the fluid naturally circulates in the evaporator system.
