2004-3-19·Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

Boiler Operation with Low Furnace Pressure

Low furnace pressure if not handled by the boiler operator at the right time can lead to furnace implosion. Each large balanced draft boiler is designed for a particular implosion pressure. Like the high furnace pressure withstanding capability the balanced draft furnaces have a good implosion pressure withstanding capability. Implosion is large pressure acting on the walls of the furnace from

How to control the working pressure of a boiler - Quora

Most modern boilers are not controlled by an ON/OFF switch as they did in the past if automatic. A pressure switch with a cut out at high pressure and a cut-in at some span below the high cut-off is a tad old-fashioned, though still used in domest

2013-11-27·As MS flow incorporates pressure and temperature correction, a sudden loss of MS Pressure TX (one used for pressure compensation), results into lower MS flow measured by the system. The three element drum level control reduces the FW flow in response. Thus, BFPs start unloading and the drum level drops fast.
