PDF Steam Pressure Reduction: Opportunities and Issues

Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.

Introduction to Steam Distribution | Spirax Sarco

When the boiler main isolating valve (commonly called the 'crown' valve) is opened, steam immediately passes from the boiler into and along the steam mains to the points at lower pressure. The pipework is initially cooler than the steam, so heat is transferred from the steam to the pipe.

A steam boiler uses more energy to boil the water, but uses less energy during the transfer of heat. A hot water boiler uses less energy to create hot water, but more energy during the transfer of heat. Because steam boilers are so efficient at heat transfer, they're often used in extreme levels of cold or in old or under-insulated homes.

The water tubes are heated by heavy fuel oil, which is

Although the supply pipe is designed to carry steam, it will have some condensate in it. As a result, the steam trap at the end of the main has to allow condensate (but not steam) into the return piping system. The slope of the supply main is typically 1 inch in 20 feet, again to allow the condensate to flow back to the boiler.

Boilers - Commercial Heating | Oliver Mechanical Services

Boilers are large vessels that contain water and a heat source (usually oil, coal, or gas). The boiler transfers heat from the heat source into the vessel and as heat is applied to the water, it turns to steam. The steam is then expelled through a pipe to be used as a heat source. There are two types of boiler systems - closed and open.

If the piping can't separate the water from the steam, the water will condense the steam, and it will take a long time to heat the building. Check, too, the water's cleanliness and pH.

Tips for a Successful Steam Boiler Replacement | U.S

Steam boilers should never operate without main pipe insulation. The main steam lines should be insulated with a minimum of 1" pipe insulation. Main pipes that are not insulated cause higher fuel bills, more water in the system due to increased condensation in steam mains, slower heating, and possible system noise issues.
