Fire-tube boiler - Revolvy

A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam .

Optimizing hot water systems with condensing boilers

Full condensing boiler systems are simpler to design than partial and conventional noncondensing boiler systems. Some condensing boiler systems can be set up in a variable primary flow (VPF) arrangement with a minimum flow bypass control valve to maintain boiler minimum flow to allow a piping and pumping configuration that minimizes pumps and
