Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa; 1,013.25 mbar), which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth

Superior Boiler offers both Low Pressure and High Pressure packaged steam boilers. These are ready-to-install systems featuring a perfectly matched powerful and efficient burner/boiler combination ideal for Space Heat and Industrial Process applications.
The average boiler steaming rate is 15000 kg/h, and the plant operates for 8000 h/year. The fuel used is gas on a firm tariff of £0.011/ kWh, and the boiler efficiency is estimated as 80%. Make-up water temperature is 10°C and insulated condensate return lines ensure that condensate will arrive back at the boiler house at 95°C.
For example the high pressure steam boiler in a locomotive may operate at pressures of 200-250 psi (1.38-1.72 MPa) or even higher. Specially constructed very high pressure steam boilers may operate at pressures over 1,500 psi. - Wikipedia 4/14/14 Watch out: You won't find high pressure steam boilers being used for residential building heating
ATMOSPHERIC BOILER - a boiler in which combustion air/flue gases are drawn through the boiler without a fan. Modulating atmospheric boilers are designed to control the output (size of flame) to match the boilers variable load requirements. During this process the burner is designed to stay at the correct fuel / air ratios across the complete

However, steam at atmospheric pressure is of a limited practical use. This is because it cannot be conveyed under its own pressure along a steam pipe to the point of use. Note: Because of the pressure/volume relationship of steam, (volume is reduced as pressure is increased) it is usually generated in the boiler at a pressure of at least 7 bar g.
In a typical wet steam turbines, the exhausted steam condenses in the condenser and it is at a pressure well below atmospheric (absolute pressure of 0.008 MPa, which corresponds to 41.5°C). This steam is in a partially condensed state (point F), typically of a quality near 90%. Note that, there is always a temperature difference between
