Intermittent blowdown requires large short-term increases in the amount of feed water put into the boiler, This type of blow down is common in high-pressure boilers. Blowdown calculations The quantity of blowdown required to control boiler water solids
Bottom blowdown should be of short duration, on a regular basis. These are determined by boiler design, Low pressure boilers typically blowdown directly from the boiler to a floor drain. However, even with low pressure boilers the presence of live steam, very

Composite boilers are used with Diesel engines, since if the exhaust gas from the engine is low in temperature steam can be maintained by means of an oil fired furnace.
"The ability of watertube boilers to generate superheated steam makes these boilers particularly attractive in applications that require dry, high-pressure, high-energy steam, including steam turbine power generation". Owing to their superb working properties, the use
Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler. frequent short blows are preferred to infrequent lengthy blows. The length and frequency of the blowdown is particularly important

materials<br />The pressure vessel in a boiler is usually made of steel (or alloy steel), Water tube boilers are used for high-pressure boilers. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.<br /> 11.
Most high-pressure and large boilers are of this type (Figure 9.2.2). It is important to note that the small tubes in the water-tube boiler can withstand high pressure better than the large vessels of a ire-tube boiler. In the water-tube boiler, gases low over water-illed
