how to force the vacuum gas boiler

Common Boiler Problems | Boiler Faults & Troubleshooting

Jan 01, 2012 · The vacuum itself exerts no force; the air outside of the container exerts the force. Venturi vacuum pumps use compressed air to draw the gasses—along with any debris, dirt or dust—out of the chamber. The gas and its particulates are all pulled into the pump. In the venturi, compressed air passes through a nozzle that accelerates the air.

Understanding Pressure and Measurement | Normandale

Pressure is defined as force per unit area. In this case, the force is exerted by the impact of the gas molecules with the surface where their impact energy is transferred. The more impacts, the more force, and the higher the pressure. Since all molecules, at any given temperature, have the same energy, it doesn't matter what the gas is.

Jan 06, 2006 · Hardening involves heating the steel to a predetermined temperature, then cooling it rapidly in water, oil or suitable medium. A further application for vacuum furnaces is Vacuum Carburizing also known as Low Pressure Carburizing or LPC. In this process, a gas (such as acetylene) is introduced as a partial pressure into the hot zone at temperatures typically between 1,600 and 1,950 °F (870 and …
