Sep 21, 2018· Boilers producing saturated steam need only control pressure because the temperature is a thermodynamic property of saturated steam. Figure 2 shows a photo of a burner retrofit for a 50,000-lb/hour, 150-psi saturated steam boiler with a new burner assembly with combustion safety controls. In this retrofit, a grade no.

Fluidized bed combustion - Wikiped

Fluidized bed combustion is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials through which jets of air are blown to provide the oxygen required for combustion or gasification. The resultant fast and intimate mixing of gas and solids promotes rapid heat transfer and chemical reactions within the bed. FBC plants …

Fluidized Bed Combustion FBC Boiler - Boilersin

ADVANTAGES OF A FBC BOILER. Considerable reduction in boiler size is possible due to high heat transfer rate over a small heat transfer area immersed in the bed. Low combustion temperature of the order of 750°C – 900°C facilities burning of coal with low ash fusion temperature, prevents NOx formation, reduces high temperature corrosion and erosion,

4.5/5(1) [PPT]· Web viewWith the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.
