Boilers operating at 15 psig steam pressure or lower, known as low-pressure heating boilers, are classified in SIC 3433.
in equitorial low pressure belt , low pressure is due to 1) intense heating 2) rate of rotation of earth is max. at equator . this results in max centrifugal force at equator which pushes the air away from the surface and causes low pressure condition.
Plastic solenoid valves are used for the release of steam and water. They come in low pressure releases as well. They range in many uses but are available for use to control water supply from the municipal source.
The equator is an intensely heated throughout the year . Due to the intense heating the air in this region becomes warm and light and it rises above creating a partial vacuum .(As you know vacuum leads to decrease in air pressure) As a result a region of permanent low pressure is created called the equatorial low pressure belt.
A fluid will move from high pressure to low pressure.

Differential heating creates high-and-low-pressure areas, creating wind.
The Titanic had funnels to get rid of low pressure steam after it had been used to drive the engines.
it is a low pressure heater used in the boiler system in the thermal power plants to convert the saturated steam into super heated steam.
Differential heating creates high-and-low-pressure areas, creating wind.
Bleeding of steam means Extracting steam from Turbines for heating the feed-water. Normally, there are High Pressure Heaters & Low Pressure heaters in Condensate cycle. Steam bleed out from the turbine gets into these heaters and heats up the feed-water (generally termed as Sensible Heat Addition). The steam that was bled can be re-used as condensate in Deaerators. Steam Extractions although reduce net work output but helps in overall gain in efficiency in terms of Reduced Fuel Consumption.
I believe that is 15 PSI on a low pressure steam boiler
A boiler produces steam at a high temperature and pressure. It is used to push a piston or a turbine, to produce mechanical energy. The steam coming out can then be used to drive a low-pressure turbine and so on. At the end the steam can be condensed to extract the latent heat, and then the water goes back to the boiler.
