This type generally gives high steam production rates, but less storage capacity than the above. Water tube boilers can be designed to exploit any heat source and are generally preferred in high-pressure applications since the high-pressure water/steam is contained within small diameter pipes which can withstand the pressure with a thinner wall.
Characteristics of boiler feed water. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc,

A water tube boiler is typically formed of four parts, a lower feed water drum – sometimes known as a mud drum – an upper steam drum with water surface from which the steam is evolved, water tubes connecting the two drums together and a super heater / economiser section (depending on the quality of steam required). Water circulates by convection between the two drums with the heat passing over the banks of tubes.
saturated steam. Water enters the boiler at point A and the water gains sensible energy (hf) to point B. The change of state is referenced as point B on the chart. As the saturated steam acquires more energy from the boiler combustion process, the steam achieves a high quality, (moving left to right) as represented on the chart, points B to C.

Mar 21, 2018 · The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to
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. This means that even a small percentage blowdown can represent a high mass to be blown down.

A high pressure watertube boiler 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 heats 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 that make up the walls of the furnace to generate steam. High Pressure Water Tube Boiler: The heated water then rises into the steam drum. Here
