Boilers

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

The chemical reaction of fuel and oxygen can occur even at ambient temperatures. For this reason, a pile of coal can be a fire hazard. Small amounts of heat are given off as the coal slowly oxidizes. This in turn raises the temperature of the coal pile and increases the oxidation rate, liberating more heat. In a fire-tube boiler, the water

Steam explosion - Wikipedia

Old "fire-tube" boilers often failed due to poor build quality or lack of maintenance (such as corrosion of the fire tubes, or fatigue of the boiler shell due to constant expansion and contraction). A failure of fire tubes forces large volumes of high pressure, high temperature steam back down the fire tubes in a fraction of a second and often
