Boilers - Classification

Classification of boilers according the ASME Boiler and Pressure Vessel Code.

According the "ASME Boiler and Pressure Vessel Code" boilers may be classified as

boilers in which steam or other vapor is generated at a pressures exceeding 15 psig
high temperature water boilers intended for operation at pressures exceeding 160 psig and or temperatures exceeding 250 degrees F

boilers in which steam or other vapor is generated at a pressures not exceeding 15 psig
high temperature water boilers intended for operation at pressures not exceeding 160 psig and or temperatures exceeding 250 degrees F

ASME - International Boiler and Pressure Vessel Code
The International Boiler and Pressure Vessel Code safety rules governing design, fabrication, and inspection of boilers and pressure vessels, and nuclear power plant components during construction.
Boiler - Efficiency
Combustion gross and net calorific value.
Boiler Blowdown
Suspended solids in the feed water will remain in the boiler when steam is generated.
Boiler Blowdown Rate
Calculate boiler blowdown rate.
Boiler Horsepower
Boiler horsepower vs. heat transfer area.
Boiler Rooms - Sizing
Minimum area in a boiler room.
Combustion Processes and Combustion Efficiency
Typical furnace combustion efficiencies in fireplaces, space heaters, boilers and more.
High Pressure Steam Systems - Safety Valve Capacities
Sizing safety valves according boiler output power in high pressure systems (kW and Btu/hr)
Intermittent Combustion and Boiler Efficiency
Efficiency reduction due to intermittent boiler operation.
Steam Boiler Rating vs. Feed Water Temperature
Boiler output vs. feed water temperature.
Steam Boiler Shells - Stress vs. Boiler Pressure
Calculate the stress in steam boiler shells caused by steam pressure.
