2011-7-19 · 2.2 Super-critical Boilers When water is heated at a constant pressure above the critical pressure its temperature is never constant and no distinction between gas and liquid can be made, the mass density of the two phases is the same. Properties of the water in the super-critical boiler continuously change from liquid to gas (steam), for example:

Boiler - Azarab

Boiler duty is to turn liquid (water) into super saturated steam, but in industry, all devices turning liquid to super heated steam are called boiler. Boilers are being used in steam production units for general, electrical and industrial uses, and depend on their planning can make use of charcoal, mazut, gas, oil and natural gas as their fuel.
