Description

A short boiler blowdown is performed by quickly opening the blowdown valve.This createsa short-term low-pressure areaaround the blowoff opening atthe bottomof the boiler, causing a suction effect thatremoves accumulated sludge and sediments that have setted out in the lower part of the boiler.

Thesuction effectofan intermittentblowdown isonlyeffectiveat the moment when the valve is being opened.For this reason the valve should only be opened for approx.2 seconds.Longer opening periods waste boiler water.

For the closing process the design of the valve is of great importance. The closing force of the spring of the intermittent blowdown valves (M)PAis increased by the boiler pressure,whichmeans that the valve is in a good condition for breaking up any dirt particles settled on the valve seat/plug,thus ensuring a positive shutoff.

Theservice life of thevalveseat/plug is further increased by the pressure reduction that takes place in the radial stage nozzle installed downstream of the valve.The time interval between bottom blowdownprocessescanonlybe calculated indirectly by taking the boiler efficiency,the feedwater qualityand theadmissible boiler water quality into account.

Application

In steam boiler plants operating without constant supervision. Automation of intermittent blowdown by generating electric pulses to initiate a blowdown cycle via the GESTRA rapid-action intermittent blowdown valve MPA.

If space underneath the boilder is of concern, (M)PAs that can be tilted by 4 5 ^ { \circ } are available on request.

Ingress of Oil in Cooling Water Systems Digital Indicator

GeSTRA

Purpose and Application of Oil Detector

The oil detector ORGS 11-2 is used for monitoring coolingwater to detectany ingress of oil.An alarm and control unit installed downstream of the detector will dump contaminated cooling water,thereby preventing oil contamination of the installation to be cooled. The equipment detects all low-density matter that is insoluble in water, not emulsified,and hasalower electricalconductivity thanwater. Antirust oils,which emulsify in cooling water, do not trigger an alarm.

Principle ofMeasurement

Vortex flowmeter

The design is based on the Karman vortex street principle using a body installed perpendicular to the axis of the pipe.The vortices generated in the flow stream produce pressure oscilations which are converted into electrical signals bya sensor.The output signal is then evaluated and processed in the flow computer.

System Description

stem1Injection cooler wit fixed jet orifices

The coolingwater is injected through special jet orifice into thesteam flow.Theamount isadjusted by a control valve upstream of the desuperheaterand controlled by the high differential pressure.The typeand numberof nozzlesare dictated by the operating data. The internals of the pipe installed downstreamof the equipment prevent temperature shocks at the external pipe.

System2 Water-bathdesuperheater

The heat of the superheated steam causes the cooling water/condensate to evaporate, thereby cooling thesuperheatedsteam.The steam produced is conducted through steam separating units and has a steam content of more than 9 8 % (i.e. less than 2 % residual moisture).

Criteria forSystemSelection

1.What is the ratio betweenminimumand maximum steam quantity in the control range?
2.What is the pressure and the temperature of the available cooling water?
3.How close must the temperature of the desuperheated steam be to that of saturated steam?

Application

To avoid corrosion damage to steam boiler plants,the content of aggressive gases, such as oxygen and carbon dioxide,in the feedwatermust beas lowas possible.The German Technical Supervisory Association (VdTUV) has issued directives concerning boiler feedwater quality which are applied by German boiler manufacturers when giving a warranty on their boilers. Thermal deaeration in addition to chemical deaeration is very important for maintaining the required feedwater quality.

Recommendation:

For quality of soft water: Concentration of chloride approx. 5 0 ~ { m g / l } Conductivity approx.250 uS/cm

Application

Condensate flash vessel

Condensate flashvesselscanbeused inall steam plants where condensate from steam consumers isreduced toa lowerpressure. This pressure drop constitutes a change of the energy content that causes some of the condensate to revaporize and form flash steam.

In the flash vessel the flash steam is separated from the water,and then fed into a low-pressure steam system.The condensate remaining in the flash vessel is discharged into a condensate tank.

Blowdown flash vessel

Blowdown flash vessels are used if the flash steam formed downstream of continuous blowdown valves is to be utilized.
