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

FURNACES AND REFRACTORIES - Modern Eq

Furnaces are broadly classified into two types based on the heat generation method: combustion furnaces that use fuels, and electric furnaces that use electricity. Combustion furnaces can be classified in several based as shown in Table 2: type of fuel used, mode of charging the materials, mode of heat transfer and mode of waste heat recovery.

Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
