Safety valve - Wikipedia

A safety valve is a valve that acts as a fail-safe.An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would

15 Ways to Increase Boiler Efficiency in Your Facility

Jul 30, 2020 · Think about it; the boiler draws in cool air, heats it up, and sends it out the stack. A lower stack gas temperature is ideal because the higher the temperature, the more energy leaves with the flue gas. On the other hand, the boiler system takes in cold water, heats it to steam, and uses the heat.

Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
