A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Learn More

May 01, 2005 · A 200-foot, 4-inch, Sch. 40 main steam line would cost three times more than a 200-foot, 2-inch main line. Undersized piping downstream of pressure reducing valves Assume the boiler is set at 200 psig, 2-inch steam lines are used, and a 2-inch pressure-reducing valve (PRV) is specified to provide the 50-psig steam required by the process.Learn More
Jul 29, 2009 · A basic boiler is a machine with the simplest arrangement of the internal parts. The main job of a boiler is to make high pressure steam. The feed water supplied to the boiler drum utilizes the heat of the energy released by burning the fuel. This energy of the burning fuel is stored in the form of steam with high temperature and pressure.Learn More
pipework to the point where its heat energy is required. Initially there will be one or more main pipes, or 'steam mains', which carry steam from the boiler in the general direction of the steam using plant. Smaller branch pipes can then carry the steam to the individual pieces of equip-ment. A typical steam distribution system is shown in Learn More
With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.Learn More

BOILERS Bureau of Energy Efficiency 27 Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam.Learn More
A short history of boiler designs Shell and tube-saturated steam boilers of the current packaged form have been manufactured since before the second world war, and their lineage may be traced directly back to the Cornish boilers of the early nineteenth century, invented by the British inventor and mining engineer Richard Trevithick (1771–1833).Learn More
Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.Learn More
