The pressures assumed in the tp are typical of the range of values experienced in steam headers during start-up asme tdp 1 2006 the STG. Steam Header Drain Control Logic Steam header drains function in accordance with the control logic assigned to the power-operated valve in the drain line.

The damage due to turbine water induction and water hammer in power plants is more common than you might imagine and has been experienced at many power plants. Figure 4 shows the final iterated critical pressure, which represents the mass flow rate where the basic Bernoulli equation and the td; velocity equation agree. Typical drain pot with redundant level elements.

Preventing Turbine Water Damage: TDP-1 Updated

They were placed on your computer when you launched asme tdp 1 2006 website. About ASME ASME is a not-for-profit membership organization that enables collaboration, knowledge sharing, career enrichment, and skills development asme tdp 1 2006 all engineering disciplines, toward a goal of helping the global engineering community develop solutions to benefit lives and livelihoods. In addition to the equations cited above, the basic Bernoulli and sonic flow equations are required as part of the calculation procedure.

If Vactual does not exceed Vs, then P2 will remain at 15 psia and the flow is not choked. The practices cover design, operation, inspection, testing, and maintenance of those aspects of the following power plant systems and equipment concerned with preventing the induction of water into steam turbines: Calculating steam flow through drains.

Proper Sizing of Steam Header Drains Prevents Water Induction ASME TDP-1 –

How to download and install: Full Description This Standard includes recommended practices concerned primarily with the prevention of water damage to steam turbines asme tdp 1 2006 for fossil-fuel-fired electric power generation. Figure 2 also illustrates that the rate of steam flow through the drain line decreases with a decrease in upstream pressure P1 and an increase 2006 drain line Resistance Factor k.

No items in cart. In this case, the choke point occurs asme tdp 1 2006 pressure falls off and velocity increases to sonic velocity at the downstream end of the pipe. Note that for a given steam header pressure P1 the rate of steam flow through the pipe reaches steady-state conditions for long pipes. This computation, though tedious, is quite simple when programmed in a spreadsheet program such as Microsoft Excel.

Note that the relatively low pressure of psia is typical for the reheat section during STG start, and this low pressure could limit steam flow through the drain line.

To reduce drain line resistance, use a shorter line length or increase pipe size. Asme tdp 1 2006 expected, the results of both sets asme tdp 1 2006 calculations illustrate that the vent inlet and vent outlet pressures decrease with ssme vent sizes. Please login to your authorized staff account to use this feature.

Both water induction and water hammer phenomena can be very destructive to steam piping and equipment. This article presents a useful calculation procedure for sizing drain lines so that they do not restrict the necessary drain flows.

Zaheer Akhtar, PE Not directly discussed in the ASME asme tdp 1 2006 is the fact that asje presence of water in steam lines can also result in water hammer in the steam piping. The results for a nominal asme tdp 1 2006 drain line for three different upstream pressures P1 are shown.

This calculation procedure can be used by plant designers to determine the blowdown flow rate through a specific piping system for any given upstream pressure. April 8, Price: To provide moisture-free steam to the STG, the supply steam lines need to be adequately sloped and fitted with appropriately located drain lines capable of discharging any and all collected condensate Tvp 1.

Similarly, if asme tdp 1 2006 drain line is discharging to the atmosphere, it is usually connected to a large-diameter manifold joined to the vent stack or directly connected to the vent stack. Asme Tdp 1 Pdf File azme Drains asme tdp 1 2006 downstream of attemperators are usually fitted with a drain pot with level instrumentation and are used to collect and xsme spray water leakage downstream of the attemperating station.

Domestic Water Pipe Sizing. The modified Darcy formula can be represented as tdo, in equation [1]: Our thanks to Dr. One important requirement for safe and reliable operation is preventing water induction in the steam turbine and avoiding water hammer in the steam piping system.

Full Description This Standard includes recommended practices concerned primarily with the prevention of water damage to steam turbines used for fossil-fuel-fired electric power asme tdp 1 2006.

Althoughwater induction into the high and intermediate pressure turbines has historically been recognized as the most damaging, experience has qsme that water induction in low pressure turbines can cause significant damage and should also be taken seriously.

The practices address damage due to water, wet steam, and steam backflow into a steam turbine.

Note that the horizontal line represents choked flow for the given steam pressure. I agree to the Terms. The job adme the plant designer is to ensure that, under asme tdp 1 2006 worst-case conditions, the drain line and the downstream manifold or vent are properly sized.
