The steam-generating boiler's roots go back to the late 1700s and early 1800s with the development of the kettle-type boiler, which simply boiled water into steam. The water was placed above a fire box and then boiled into steam. It wasn't until around 1867, with the development of the convection boiler, that the steam-generating industry

That's optimal at normal temperatures. Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at
Read MoreSPS 341.03 Note Note: A proposed alteration for an existing boiler, pressure vessel or power piping may necessitate modifying other components in order to make the proposed alteration comply with this chapter – and some alterations may necessitate modifying other features of a building, such as an automatic fire sprinkler system, that must comply with requirements in chapters SPS 361 to 366
Read MoreHi Simonok, It has been my low pressure steam boiler experience that the boiler will and should fire for much longer than two minutes.The short cycling of the boiler does seem like it might not be on long enough to build steam pressure. 98c should be getting you
Read MoreThe only problem I can see is that it does not appear to build pressure. I fired it up and it ran without stopping for almost an hour. The thermostat is on the 1st floor, and the 3rd floor apartment was BLAZING hot. I closed all of the radiators valves up there and still no pressure building in the boiler. I ordered a new pressure gauge, but I
Read MoreSteam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the
Read MoreFire-tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire-tube boilers, typically have a lower initial cost, are more fuel-efficient, and are easier to operate. Their capacities are up to 25tons/hr and 17.5 kg/ cm2.

Read More2015/8/23 · It's not the pressure that heats the building; it's the latent heat the steam gives up when it turns back into water. But if the air vents aren't venting, the pressure will rise, and the tug of war between the steam and the air will begin, and that's what causes the burner to short-cycle and waste fuel.

Read MoreIn fact, the Empire State building (yes, that 1250-foot building in New York) heats the entire building on steam heat with 1.5 PSI of pressure. So why 15 PSI? In the early 1900s as boiler codes and rules were being established, it was decided that a high pressure boiler would be 15 PSI and above, with anything lower being defined as a low pressure boiler.
Read MoreThe building THERMOSTATS do not normally directly control the temperature or pressure in the heating boiler. The thermostat sets the desired temperature in the building, but to the heating boiler it is working as a simple "on" - "off" switch, turning the boiler "on" until the thermostat is satisfied (the building is warm enough), then turning the boiler "off".
