Steam Boiler Shells - Stress vs. Boiler Pressure

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)

where

σ = hoop stress (Pa, N/m²)

P = boiler pressure (Pa, N/m²)

D = diameter of boiler shell (m)

t = thickness of boiler shell (m)

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.
