Safety-smelt-water explosions
One of the main hazards in operation of recovery boilers is the smelt-water explosion. This can happen if even a small amount of water is mixed with the solids in high temperature. Smelt-water explosion is purely a physical phenomenon. The smelt water explosion phenomena have been studied by Grace [14]. By 1980 there were about 700 recovery boilers in the world [8]. The liquid - liquid type explosion mechanism has been established as one of the main causes of recovery boiler explosions. Source-Wikipedia

Boiler Chemicals are used to prevent scale and minimize corrosion. The ultimate goal is to reduce water usage, save on energy and to extend equipment life.
