2016-8-13 · to the flashing of the boiler water into steam at a lower saturation temperature corresponding to the lower boiler pressure. When boiling occurs in a tube, bubbles of vapour are formed and liberated from the surface in contact with the liquid. This bubbling action creates voids, due to the rapidness of the action. This causes turbulence

2  · Heat Losses in a Boiler . 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.

The liberated acid reacts with iron (of the boiler) in chain like reactions producing HCI again and again. Thus Fe + 2HCI → FeCl 2 + H 2 FeCl 2 + 2H 2 O → Fe(OH) 2 + 2HCl. Consequently, presence of even a small amount of MgCl 2 will cause corrosion of iron to a large extent.

Alkalinity in a boiler system protects the unit against attack and maintains the proper pH level for the necessary chemical reactions to occur. Just as importantly, alkalinity provides hydroxyl ions, which form an insoluble ferrous hydroxide film on metal. The level of alkalinity required in a boiler system depends upon several factors.
