Development of recovery boiler pressure, temperature and capacity. Safety. One of the main hazards in operation of recovery boilers is the smeltwater explosion. This can happen if even a small amount of water is mixed with the solids in high temperature. Smeltwater explosion .
What is a Wood Dust Explosion? A wood dust explosion is a propagating (moving) combustion process in which an ignited dust particle ignites nearby particles and the flame proceeds from the ignition source through the premixed dust/air atmosphere. The result is heat, light, combustion gases and pressure
