  • HRSG Boiler Tube Cleaning | PressureWave Plus™ | GE Power

    GE was called into a combined-cycle plant in the southeast US that was experiencing significant gas turbine back pressure and gas-side tube fouling on the cold-end modules of the HRSG unit following an extended outage. Initially, the plant tried an alternative cleaning method to remove the corroded material.

  • Condenser Backpressure High? Check Vacuum System Sizing

    Vacuum System StandardsAir-Venting DevicesFactory Tests Versus Hei RequirementsComparing CalculationsHybrid ArrangementsClosing ThoughtsThe Heat Exchange Institute’s (HEI’s) Standards for Steam Surface Condensersprovides clear directions on capacity requirements for venting equipment when operating in either holding or hogging modes. The capacity in the holding mode is more critical, as it has a direct effect on megawatt generation. The HEI recommends that the capacity of venting equipment in the holding mode “be no less than the values shown in [HEI’s] Table 9 at the design suction pressure to ensure adequate removal capacity under commercial operating conditions.” The HEI defines the design suction pressure for electric generation service as “1.0 inch HgA or the condenser design pressure, whichever is lower.” In addition, the HEI states that the saturation temperature of the gas vapor mixture must be considered as the steam temperature corresponding to the design pressure of the venting equipment less the greater of 7.5F or 0.25 (Tsat –Tcw,inlet). Tsat is the saturation temperature of the liquid in the condenser a...

  • Why is there low pressure in the condenser of a power plant

    Negative pressure or vacuum is created in a condenser so that steam can easily flow into the condenser and more work output is obtained from the turbine. The more the negerive pressure the more will be the work output as the area under the T-S curve will increase.

  • Why vacuum may be lost or not maintained in steam turbine system?

    The condenser cannot stand the steam pressure, the condenser tubes may leak from excessive temperature. Excessive pressure will also damage the shell, the exhaust and the low-pressure parts of the turbine. Identifying leaks: First, find the leak by passing a flame over the suspected part while the condenser is under vacuum. Leaks in the flange joints or porous castings can be stopped with asphalt paint or shellac.

    The vacuum is always applied to the permeate side of the membranes. Stage [2, 3, 4, x]: This process is replicated in further stages and each stage is at a lower pressure and temperature. Condenser: The vapour produced in the final evaporation–condensation stage is condensed in the condenser, using the coolant flow (e.g. seawater).
