  • Chapter 12: Heating, Air Conditioning, and Ventilating

    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.Learn More

    High pressure. High-pressure vessels and pumps became affordable and reliable with the advent of steam power. By the mid-1800s, steam locomotives were common and the first efficient steam-driven fire engine was operational. By the turn of the century, high-pressure reliability improved, with locomotive research leading to a sixfold increase in boiler pressure, some reaching 1,600 psi (11 MPa).Learn More

  • Agricultural Anaerobic Digesters: Design and Operation

    Dec 01, 2016 · The manufacturer's rating for boilers indicated a boiler efficiency of 0. 7 with LP gas and 0.78 with natural gas. The value of 0.58 was used in calculating the needed boiler capacity due to intermittent and low-load operation. A boiler with a rated input value of 66,000 Btu/hr (19.5 kW) was selected for the Penn State digester installation.Learn More

  • Steam Accumulators | Spirax Sarco

    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). Consequently, the pressure drop is small (0.11 bar) and would not be significant in normal operation.Learn More
