INTRODUCTION TO BOILER - 123seminarsonly.com

Water tube boilers 1. Fire tube boilers : Fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or 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. There are Several

Is A Lpg Firetube Boiler Efficiency Higher Than Fuel Oil

In the locomotive-type boiler, fuel is burnt in a firebox to produce hot combustion gases. The firebox is surrounded by a cooling jacket of water connected to the long, cylindrical boiler shell. The hot gases are directed along a series of fire tubes, or flues, that penetrate the boiler and heat the water thereby generating saturated ("wet") steam.

Choosing The Right Boiler: Watertube vs. Firetube - Boiler

May 13, 2016 · Fire tube gas fired boiler. In a fire tube boiler, the flue gas travels through the tubes, which are surrounded by hot water. Fire tube gas boilers are typically designed with either three or four sets of tubes (three- or four-pass boilers). Every set of tubes that the flue gas travels through is considered a "pass". Boilers designed for three-passes have the stack at the rear, and boilers designed for four-passes have the stack at the front. WNS fire tube gas oil fired boiler …
