Classification of Boiler

High-pressure boiler: This boiler produces steam pressure above 80 bar. Sub-critical boiler: The critical point of a boiler is a condition where boiler steam reaches a temperature of 560 ° C at a pressure of 221 bar. If a boiler works below these conditions, the boiler is called a subcritical boiler.

PDF HIGH PRESSURE BOILERS High Pressure Boiler, P > 60 bar

Benson in 1922 argued that if the boiler pressure was raised to critical pressure (225 bar), the steam and water have the same density and therefore the danger of bubble formation can be easily eliminated. The technical development at that time did not allow to build turbines for such high pressures. The first high pressure Benson boiler was ...

8. The Benson boiler can be operated most economically by varying the temperature and pressure at partial loads and over loads. The desired temperature can also be maintained constant at any pressure, 9. Sudden fall of demand creates circulation problems due to bubble formation in the natural circulation boiler which never occurs in Benson boiler.

US4484531A - Cyclic velox boiler

A cyclic velox boiler is described wherein solid carbonaceous fuels are burned in pressure vessel containers by cyclic compression and expansion with air or with air and steam as usual gas reactants. During compression air is forced deeply into the pores of the solid fuel and rapid primary burning to carbon monoxide results due to the large internal pore area available.
