For steam boilers, a small overpressure is required, usually 3% or 5%. For most other applications, 10% overpressure is required, but according to API 520, for special applications such as fire protection, larger valves with overpressures of 20% are allowed.Get Price
A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress. Water Get Price

Fire Tube Boilers. In a fire tube steam boiler, the tubes on the boiler are heated, and the water circulates around the tubes. The heat inside the tubes is produced by gases heated by coal or oil, and it is transferred by thermal conduction to the water to create steam. Fire tube steam boilers produce low pressure steam.Get Price
The term boiler is applied to the single heat source that can supply either steam or hot water (a boiler is often called a heater). Boilers may be classified according to several kinds of characteristics. They are typically made from cast iron or steel. Their construction design may be sectional, portable, fire-tube, water-tube, or special.Get Price

Using the following mass flow equation for saturated steam the pressure downstream of the surplussing valve (P2) can be calculated: In this example, at low fire, the boiler pressure is given as 12 bar g (13 bar a). It can be calculated from Equation 3.21.2 that the pressure after the fully open surplussing valve is 11.89 bar g (12.89 bar a).Get Price
Heat loss from the boiler jacket could range from 1/2% to 4% of the boiler output, depending upon operating pressure or temperature, boiler size, type of construction, and insulation thickness. Typically, the larger the boiler the lower the loss as a percentage of boiler output.Get Price
Steam Production At normal atmospheric pressure, any further addition of heat to water at 100°C will not increase the temperature but will convert some of the water into steam In order to convert water into steam 2,257 kJ/kg (971Btu/lb) of additional heat must be added This cannot be detected as a rise in temperature and is called the LatentGet Price
