Difference Between Low- and High-Pressure Boilers | Hunker

Low-Pressure Boiler Definition. The temperature in a low-pressure boiler will not rise above 250 degrees F. Because these types of boilers operate at lower pressures, they don't need to be monitored regularly and only have to be checked when the appliance begins to break down.

Low-Pressure Steam vs. High-Pressure Steam

Jun 06, 2016 · Low-Pressure Steam vs. High-Pressure Steam. For instance, lets say we wanted to move 200,000 Btus out of a boiler into a three-inch main. The velocity chart tells us that at 0 psig the steam will be moving at 30.44 feet per second once the air is removed from the system. Thats about 20 miles per hour.

4 things to look out for in steam boiler pressure controls

Sep 28, 2016 · How high is too high? When the steam pressures are higher than 5 psi, system problems start to occur. If you have a boiler set at 7 psi, the steam temperature is about 232 ° F. Steam traps will open once the steam temperature drops 10 ° to 20 °. The discharge temperature of the trap will be between 212 ° and 222 ° into a pipe at atmospheric pressure. At those temperatures, the water flashes to steam.

Low Pressure Boiler Manufacturers | IQS Directory

Low Pressure Boilers. Low pressure boilers are tanks or vessels that facilitate the transfer of heat from its source to water or steam at pressures below 15 PSI. Though high temperatures within an enclosed space result in increased pressure, these boilers are able to keep pressure at or below the atmospheric pressure of ~14.7 PSI.
