Boilers - University of Alabama

Water-Tube Boiler (1867) A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water. The water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must be

appear considerably more efficient than flash or unfired boiler systems over a wide range of operating conditions. Specifically, direct-boiling systems should deliver up to 13% more net energy on an annual basis than an unfired boiler system using a heat-transfer oil, and up to 12% more net energy than a flash system. Furthermore, direct

An Approach towards Efficient Operation of Boilers

Boiler Efficiency Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilised to generate steam. There are two methods of assessing boiler efficiency [4]. 1) The Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel.
