Read MoreA steam boiler capacity is 30 tons of steam per hour. Do. Holding capacity will always be lesser than the generating capacity. For example, for 150 ton/hr Bi-Drum oil fired boiler, Total hold up volume is around 61 tons, and Steam drum capacity is merely 13 tons ( But in running condition it will hold ha. Get A Quote.

Read MoreKefid · STEAM Factor of Evaporation. The factor of evaporation for any given feed water temperature and boiler pressure is calculated by dividing the total heat above F. in one pound of steam at the given pressure minus the total heat in one pound of the feed water above F. by the latent heat of steam at F., which is 970.4 British Thermal Units.

Read MoreIn this case, the amount of continuous blowdown is 10% of the amount of steam produced by the boiler. Let's calculate the salinity of the boiler water using the conversion factor (n) equaling to 0.5. S bw = 7798*0,5=3899 mg/l. Next, we will calculate the percentage of …

Read More12/5/2020 · The American Society of Mechanical Engineers (ASME) has recommended that one boiler horsepower is equivalent to evaporation of 15653 kg of water per hour from and at 100° C. Mathematically : where. We = Weight of water actually evaporated, H = Total heat of the steam formed, and. h1 = Sensible heat of feed water.

Read MoreEvaporation ratio = quantity of steam generation/quantity of fuel consumed.For example quantity of steam Is 310 ton/hr and fuel is 55 ton/hr then the evaporation ratio is 5.63. Evaporation ratio is also known as steam fuel ratio.A drop in evaporation ratio indicates drop in boiler efficiency.Boiler evaporation ratio depends on fuel quality.
