How to properly maintain two boilers on same steam

2008-1-20·I was wondering also in the case of two boilers on the same steam header, and feed by seperate return pumps from a common return tank. When turning off and valve down one of the two at the header main gate valve. Would the vacumn that is made draw and raise the level in the boiler that is cooling down? Is it neccessary to turn off the "down" return pump and valve off the return line.

2019-2-7·Id like to talk about header piping on steam boilers. In older boilers, the boilers were designed to have a very large open space inside, which allowed the water to boil and bubble, but not wet the top of the boiler, inside. This allowed for space inside the boiler for the steam to form and let the water drop

2019-8-3·When an excess supply of exhaust or low-pressure steam is already available, there is little justification for installing heat recovery equipment. If economically justified, boiler water blowdown can be used to heat process streams. In most cases, boiler water blowdown heat recovery systems use flash steam from the flash tank for deaeration.
