Boilers - Classification

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

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.
Intermittent Combustion and Boiler Efficiency - Efficiency reduction due to intermittent boiler operation.
Safety Valve Capacities in High Pressure Steam Systems - Sizing safety valves according boiler output power in high pressure systems (kW and Btu/hr)
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.
