When we were not covered in steam from spraying the condensers with a hose to remove salt encrustation, I was assisting the fifth engineer to pack grease boxes on top of the boiler in 140°F temperatures, which we could only stand for five minutes at a time.
Read MoreThe off-gas at a rate of 66,000 Nm3/h leaves the afterburner chamber at a temperature of 1000°C. Heat is recovered in a steam boiler. The gases leave the boiler at 270°C. Steam is generated at 25 atm and superheated to 250°C at a rate of 34 t/h. A steam turbine generates electric power at the rate of 1320 kw/h consuming 22 t/h steam.

Read MoreMay 15, 2020 · On the other hand, thermal fuel-fired boilers often have much higher efficiencies (80% or higher), making steam derived from fuel-fired boilers less expensive than steam produced by electric boilers. However, the correct approach is not to look at boiler efficiency in isolation, but to also consider the efficiency of the service provided by the

Read MoreCreep failure is an important phenomenon for steam and chemical plants which operate at high temperatures of 450 to 550°C, boilers, ovens, gas turbines, supersonic jets, rockets, missiles, and nuclear plants all working at very high temperatures. Creep failures or ruptures are easy to identify due to the deformation (necking) that occurs.
Read More"Fossil fuel-fired steam generator" means a furnace or boiler used in the process of burning a fossil fuel for the primary purpose of producing steam by heat transfer. (bb) "Foundry cupola" means a stack-type furnace used for melting of metals, consisting of, but not limited to, furnace proper, tuyeres, fans or blowers, tapping spout, charging
Read MoreFuel oil (also known as heavy oil, marine fuel, bunker, furnace oil, or gasoil) is a fraction obtained from the distillation of petroleum (crude oil). It includes distillates (the lighter fractions) and residues (the heavier fractions).. The term fuel oil generally includes any liquid fuel that is burned in a furnace or boiler to generate heat, or used in an engine to generate power.
