    Water-tube boilers are available for all practicable pressures and outputs. The largest are for up to 5000 ton/h, super critical up to about 35 MPa with both superheater, and reheater up to about 600°C. The water-tube boiler consists of one or more steam drums and a lower water drum, connected by tubes.Learn More

  • Boiler Operation & Boiler Maintenance | HSB Locomotive

    Boiler combustion efficiency is the suggestion of burner capability to burn fuel. The burning efficiency depends on two different parameters such as excess O 2 levels in the exhaust and unburnt fuel quantity in the exhaust. The unburnt fuel quantity in the exhaust decreases with an increase in the excess air amount. In addition, this results in Learn More

  • Boiler Efficiency - an overview | ScienceDirect Topics

    The heat from the burner is transferred to the water tubes. As water flows through the tubes, the combustion gases heat the water and produce steam. This steam is collected in the upper drum, while combustion gases exit the boiler stack as flue gas. Several types of tubes are found inside the boiler.Learn More

  • Foaming and priming in boilers - Lenntech

    Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of Learn More
