Classification of Boiler Draught: Natural, Artificial, Steam Jet and Mechanical. Draught may be defined as the small pressure difference which causes a flow of gas to take place. In case of a boiler the function of the draught is to force air to the fire and through a boiler furnace and flue, and to discharge the products of combustion to atmosphere via stack or chimney.
Read MoreThe Model HE is a single pass carbon steel vertical boiler of the tubeless design that includes an integral furnace and extended heat transfer surfaces. In accordance with the latest edition of the ASME Code, the boiler is constructed for either low pressure steam or high pressure steam, up to 150 psi. 1. Gas Flow.

Read MoreA type of boiler known as the Benson generates steam at 3,200 lb. per sq. in., supplied through a reducing valve to high-pressure turbines working at 880 lb. In 1930 a boiler of this type was tried in the Hamburg- Amerika liner Uckermark, 7,021 tons gross.
Read MoreFlash Steam Boilers. The VAPOMAT range of locally manufactured flash steam boilers consist of a standard range based on steam output, ranging from 100 kg/h up to 2,500 kg/h per unit. These can be supplied at standard steam operating pressure limits of 1000 kPa (10 Bar) or up to 4000 kPa (40 bar) on request. The VAPOMAT flash-type steam boiler

Read MoreEvery steam system consists of the following major components: In the boiler, heat is added to liquid water to generate steam at a certain pressure. Boiler pressure is used to control the thermal capacity of the steam and to motivate the steam through the system. Steam exits the boiler through piping referred to as the steam header.
