What is a Steam Boiler? Classification of Steam Boilers

Todays steam generating systems owe their dependability and safety to more than 125 years of experience in the design, fabrication and operation of water tube boilers. Boiler classification can be based on many factors like usage, fuel fired, fuel firing system, type of arrangement etc. The commonly known types are pulverized coal fired boilers, fluidized bed boilers, super critical boilers

Classifications | Boilers Guide

Boilers are classified into different types based on their working pressure and temperature, fuel type, draft method, size and capacity, and whether they condense the water vapor in the combustion gases. Boilers are also sometimes described by their key components, such as heat exchanger materials or tube design.
