Scaling in boilersLenntech

Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the

Performance of Boiler Effiency Power and Heat Balance

 · We know that the efficiency of a boiler is the ratio of heat used in producing steam to the heat released in the furnace. Also heat utilised is always less than the heat liberated in the furnace. The difference of heat liberated in the furnace and heat utilised in producing steam is known as heat loss in the boiler.

What s the Difference Between a Heater Furnace and Boiler

 · A boiler s job is to turn water into steam which is denser than air and lighter than water. Air doesn t hold heat as well and water is difficult to move so steam is a good medium for transferring heat to where its needed. In most instances a small furnace or heating device is attached and provides the heat to get the water steaming.
