The carbon monoxide produced by its combustion reduces iron oxide (hematite) in the production of the iron product. However, agglomerates of combustible materials that have lengths that are large compared to their diameter (and will not usually pass through a 420 μm sieve) can still pose a deflagration hazard. such as (F) Carbon Black, coal or Coke Dust, (G) Flour, Starch or Grain Dusts. The pressure increase rate is generally represented by a constant Kst,, different for every material, and which can be measured experimentally by … Since smoke-producing constituents are driven off during the coking of coal, coke forms a desirable fuel for stoves and furnaces in which conditions are not suitable for the complete burning of bituminous coal itself. The facility has isolation devices to prevent deflagration propagation between pieces of equipment connected by ductwork. Explosions have occurred when the flow drops and flames in the burning chamber pass back along the ductwork delivering fuel. Respiratory protection: None needed under normal use conditions with adequate ventilation. Coke dust may form combustible mixtures with air.
