industrial boiler drum pressures ranges

Fluidised Bed Combustion Boiler,PCFB – Pulverised Coal Fired Boiler,Oil Fired Boiler .Super critical boiler At drum pressure of ∼200 bar and SH/RH temperature of 540/565°C, limits are reached in natural circulation drum-type boilers in respect of steam pressures and temperatures with

In the water tube boiler the upper drum (Boiler steam drum) provides for separation of steam from water. It also provides liquid holdup capacity (typically 10 to 60 seconds) to allow for a dynamic response to load changes without losing liquid in the downcomer and riser tubes. The size of …

"O" Type boiler pressure ranges from 250 PSIG to 1,500 PSIG and steam temperatures up reach to 1,050 degrees F. FUELS: NATURAL GAS, BIO GAS, OFF-GASSES OR #2 - #6 OIL . For more information on O type watertube boilers, or to discuss your specific steam plant needs, contact the experts at Industrial Boiler & Mechanical.

According the "ASME Boiler and Pressure Vessel Code" boilers may be classified asSection I Power Boilers - process boilers, power boilers and high pressure boilers. 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

Jul 09, 2011· Re: Boiler Drum Size for Different Pressures and Capacities 07/09/2011 8:51 AM Rajeswari, basically the limiting velocity should be the criteria for design, which depends on boiler capacity in (tones/hour) and pressure.
