The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5). Cooler feedwater is fed into a drum, which is placed longitudinally above the heat source. The cooler water falls down a rear circulation header into several inclined heated tubes.

Nov 27, 2009 · Marine boilers produce high pressure superheated steam to drive the turbines. The steam is generated by the water tubes which connect the water drum to the steam drum. Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum. The water tubes are heated by heavy fuel oil, which …

A superheated steam boiler pushes past the saturated steam curve to generate steam with no moisture (or wetness) to it. The dry nature of superheated steam boilers is a great option for turbines as well as drying, cleaning, and curing applications.

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

The superheated steam goes to the steam turbine generator, produces electricity, and is condensed producing boiler feed water. The steam condenser is usually a shell and tube type heat exchanger supplied with cooling water. Alternatively, air-cooled steam condensers can be used. Some of the electricity generated is used in the acid plant. The

In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.

Steam boiler in poultry feed processing plant. Where steam is used in the poultry feed process, a steam boiler is needed. A pellet mill with a capacity of 1.0 – 1.5 Tons Per Hour of pellets would require a steam generation plant capable of producing about 60-90 kg./hour of steam at 100 – 150 psi. In poultry feed processing plant, Steam boiler fuel can be: Sawdust, rice husk, cotton stalk
