In a typical drum boiler, the superheater outlet pressure might be 2700 psig while the reheater outlet pressure might only be 580 psig (Kitto and Stultz, 2005). They are used to help control steam temperatures, control steam flow pressure loss, and optimize heat

SZS Oil Fired Boiler Product Description SZS series oil fired steam boiler is double drum, longitudinal layout, D type structure. The right side is the furnace, and the left side is the convection tube bundle. The superheater is arranged in the convection tube bundle, and is fixed on the body base via the movable support of the lower drum.

The types of equipment in which they have been used range from domestic open fires, convection room heaters and hot water services to large steam boilers. ( Finlayson and Varley, 1962 ). Brick kilns are fired by briquettes in crushed form and clay product dryers can use hot gases for direct drying because the low sulphur content of briquettes does not cause staining of the product ( Varley et

Condensing steam turbine ' 1.1.2 Boiler " A boiler generates steam at the desired pressure and temperature by burning fuel in its furnace. Boilers are used in both fossil-fuel and nuclear-fuel electric generating power stations. A boiler is a

The energy from the sunlight is used to generate and superheat steam in a forced circulation drum-type boiler, with the superheated steam being used to produce electricity. The latest design for this technology will be supplied to Brightsource's Invanpah Solar Electric Generating System.

By far the most widely used and most powerful turbines are those driven by steam. Until the 1960s essentially all steam used in turbine cycles was raised in boilers burning fossil fuels (coal, oil, and gas) or, in minor quantities, certain waste products.

Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam.

Steam Boiler A boiler is a pressure vessel which is used to generate high-pressure steam at a saturated temperature. At this high pressure and temperature generally, bi-drum water tube boilers are used. Thermodyne Engineering Systems manufactures

Marine boilers are of two types namely the water tube boiler and the fire tube boiler. The water tube type boiler is used for high-pressure, high-temperature, high-capacity applications. The Main boiler design depends on its application, ie. for motor ships, a
Read MoreThis led to the "tube and tile" boiler design around the early 1920s. A tube and tile boiler used large, widely spaced tube walls (6 in. diameter tubes on 9 in. centers) to help cool the surface temperature of the brick. This was a new and radically different design.

(In 'large utility boilers', the feedwater is supplied to the steam drum and the downcomers supply water to the bottom of the waterwalls). To increase economy of the boiler, exhaust gases are also used to pre-heat the air blown into the furnace and warm the feedwater supply.

The capacity of cross drum ranges from 700kh/h to 240000 kg/h. 3. Stirling boiler: A Stirling boiler has near-vertical, almost straight water tubes that zig-zag between a number of steam and water drum. Usually, there are three banks of tubes in a four drum layout.
