Calculate the stress in steam boiler shells caused by steam pressure.
The stress in a steam boiler shell can be calculated as
σ = P D / 2 t (1)
σ = hoop stress (Pa, N/m2)
P = boiler pressure (Pa, N/m2)
D = diameter of boiler shell (m)
t = thickness of boiler shell (m)
- Sizing of steam and condensate pipe lines - pressure loss, recommended velocity, capacity and more.
- Combustion gross and net calorific value.
- Suspended solids in the feed water will remain in the boiler when steam is generated.
- Calculate boiler blowdown rate.
- Steam boilers output can be expressed in Boiler Horsepower, MBTU or in Pounds of Steam delivered per hour.
- Classification of boilers according the ASME Boiler and Pressure Vessel Code.
- Temperature changes introduces stress fixed pipes.
- Saturated Steam Table with steam properties as specific volume, density, specific enthalpy and specific entropy.
- Steam table with sensible, latent and total heat, and specific volume at different gauge pressures and temperatures.
- Stress is force applied on cross-sectional area.
- Radial and tangential stress in thick-walled cylinders or tubes with closed ends - with internal and external pressure.
- Stress is force per unit area - strain is the deformation of a solid due to stress.
