2016/9/4 · Boilers: Introduction and Classification. The boiler system comprises a feed-water system, steam system, and fuel system. The feed-water system supplies treated water to the boiler and regulate it automatically to meet the steam demand. Various valves and controls are provided to access for maintenance and monitoring.Get Price
Because of the fact that the nucleate boiling occurs around the furnace of firetube boilers, a further factor affecting the furnace metal temperature (besides firing rate) is the boiler pressure. It is for this reason that, in high-rise buildings, the boiler should either be located on the top floor of the building, or isolated from the building pressure by means of a heat exchanger.Get Price

Low-Pressure Boiler: The maximum pressure is of 15-20 bar and is used for the purpose of heating High-Pressure Boiler: This boiler has a maximum pressure of more than 80 bars Supercritical Boiler: These are used to produce steam at a pressure greater thanGet Price
Iron – occasionally in high pressure boilers where the iron content is high in relation to total solids, blowdown may be based upon controlling iron concentrations. High concentrations of suspended iron in boiler water can produce serious boiler deposit problems and are often indications of potentially serious corrosion in the steam or steam condensate systems.Get Price
Modern high-capacity boilers are of water tube type. The boiler circulation system is constructed of tubes, headers, and drums joined in an arrangement that provides water flow to generate steam. Water tubes have high pressures and capacity than shell tube boilers.Get Price
Pressure gauges are connected to the steam space of the boiler and usually have a ring type siphon tube which fills with condensed steam and protects the dial mechanism from high temperatures. Pressure gauges may be fitted to other pressure containers such as blowdown vessels, and will usually have smaller dials as shown in Figure 3.7.9.Get Price
The boiler works on the same principle as the water is heated in a closed vessel and due to heating, the water changes into steam. This steam possesses high-pressure kinetic energy. The boiler contains water. The water is heated to its boiling temperature by the Get Price
