Boiler Steam Drum Holding Time

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.
