Get price1/4/2012 · "One pump could not maintain boiler drum level and header pressure during sudden steam load changes," he replied. Wow! Two pumps in parallel should double the feedwater flow or increase the pressure to near a maximum shut-off head of 360 psig at half flow rate, I thought.
Get priceIn addition to the effect of the boiler margin, the boiler feed pump is designed to produce a rather higher feedwater flow than that needed by the normal boiler design condition. This is intended to cope with pump wear and transient conditions, and to act as an operational margin.
Get priceIn the single acting pump, the pumping action may take place on only one side of the piston, as in the case of the common lift pump, in which the piston is moved up and down by hand. In the double acting pump, the pumping action may take place on both sides of the piston, as in the electricity or steam-driven boiler feed pump, in which water is supplied to a steam boiler under high pressure.
Get price28/3/2016 · So in a 15,000 sq ft EDR system, where your pump is sized for 1 gpm per thousand square foot EDR, or 15 gpm, the boiler feed unit tank storage should be 15gpm times 5 minutes, or about 75 gallons of storage. A word about make-ups. The components of condensate return and boiler feed units are pretty much the same, with one noticeable difference.

Get price8/12/2017 · Boiler feed booster pumps are generally BB1 or BB2 configuration (see Figure 3.9) that have single-stage, double suction design and operate typically at four-pole motor speeds. The double suction impeller and low speed reduce the NPSHR of this pump type to suite the system design. The NPSHR by the booster pumps is much lower than that required

I've heard that residual mechanical unbalance of rotating parts is one factor that affects rotodynamic pump vibration.
Get price10/5/2021 · For pump 2B, we used the OEM, for the other two pumps, we used another vendor. The latest that we have heard from the 3rd party vendor was that the "as-found" impeller size would actually give us a higher H-Q curve (There's been talk at the plant that these pumps were "upgraded" at one point or another but no documentation has been found).
Get priceThecause of the boiler feed water contamination was found tobe a broken heating coil in one of the HFO tanks. Duringthe past year the vessel had been dry-docked at a NorthEuropean yard and the heating coil at the actual tank hadbeen renewed, but further inspections revealed that thecomplete coil was mounted without pipe clamps and as a result,vibration had caused the breakdown of the heating coil.
Get priceThe effect of transient suction pressure decay on a centrifugal boiler feed pump has been under study by Karassik, et al. Using concepts established by these authors, this paper presents an analytical method for determining the minimum permissible weight of water ratio between the deaerator storage tank and the suction piping to the boiler feed pump.
