Critical point (thermodynamics) - Wikipedia

In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. The most prominent example is the liquid-vapor critical point, the end point of the pressure-temperature curve that designates conditions under which a liquid and its vapor can coexist. At higher temperatures, the gas cannot be liquefied by pressure alone.

Aug 31, 2013· The best definition of critical point, IMHO: the saturated state where the liquid and vapor phases become indistinguishable. At the critical point, you are still at saturation, but cannot "condense". Refrigeration cycles that operate above this point are transcritical systems.

Color Cameras Turn Down the Heat in Boiler Inspection

During the online assembly process, boilers placed on nylon trays are transported on conveyors between four vision-based inspection stations (see Fig. 1). These stations are installed at critical points along the production line and control the movement of the conveyor so that no boiler is transported to the next inspection station until it has met all of the inspection criteria.

The Boiler-Commissioning Process | HPAC Engineering

Todays boilers/burners are the end result of 150-plus years of industrial development and are among the most widely applied and robust pieces of heating equipment in the world. However, although the basic boiler may stay much the same, it comes in a number of designs, is asked to play a variety of roles, and often serves as the base for a wide array of supporting or dependent equipment.

calculus - Critical points vs inflection points

The importance here is that all maxima or minima are found at critical points or endpoints of a domain. So a common way to find extrema (maxima and minima) is to find the endpoints and critical points and see which of those are extrema.

Level gauging challenges in boilers | Processing magazine

Mar 04, 2017· Most boilers will trip if the level gets too high to avoid sending water into the steam line. They also trip if the level gets too low because this could cause the boiler to run dry. Depending on the size of the boiler, a level deviation of as little as 2 or 3 inches can cause a trip.
