Prevention and mitigation of dust explosions The characteristics of the dust generated in pulp and paper mills produce a lower risk of explosion than some other industries, but actually increase the risk of fire due to higher surface area and porosity that allows air to easily mix with the dust
Early thermal weapons were used in warfare during the classical and medieval periods (approx 8th century BC until the mid16th century AD) using heat or burning action to destroy or damage enemy personnel, fortifications or territories.. Incendiary devices were frequently used as projectiles during warfare, particularly during sieges and naval battles: some substances were boiled or heated to ...
Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler startup.
Coal dust suspended in air is explosive—coal dust has far more surface area per unit weight than lumps of coal, and is more susceptible to spontaneous combustion. As a result, a nearly empty coal store is a greater explosion risk than a full one.
