SteamForm Pressure Reduc

P ressure reducing through a control valve is associated with a release ofenergy from the steam in the form of noise and vibration. Eliminatingthese undesirable effects of pressure reduction is the primary designobjective of the SteamForm valve. The FLEXIBILITY of the SteamFormvalve product allows Masoneilan to offer a wide range of cost effective

solutions, ranging from single or double stage Lo-dB trim to multi-stageV-LOG energy management trim. Each individual valve solution isengineered for Best Fit, addressing specific applications needsaccording to severity and customer specifications.

Lo-dB Technology

Smooth control and process stability are key requirements of many processcontrol applications. Critical steam applications are found in pulp & papermills, specialty chemical plants, oil refineries, and other industries that use asteady steam supply to drive a downstream process. The challenges of theseapplications, typically requiring low to moderate pressure drop control areeasily satisfied by using drilled hole single stage or double stage lownoise (Lo-dB) cages and plugs.

For more severe pressure drop applications, the SteamFormvalve can be equipped with a diffuser to provide anadditional stage of pressure reduction. These higher pressuredrop applications typically include an expanded valve outlet toaccommodate the volumetric expansion of the steam. Inaddition to reducing noise, the diffuser design also provides asecondary benefit as it disrupts the flow path and breaks thehigh energy flow jet exiting the valve trim. This flow transitiongenerates lower noise levels in the downstream pipe, andproduces turbulence to assist with desuperheating.

Low Noise, Energy Management Technology

Higher pressure drop applications such as bypass to condenserapplications found in power plants, may require a moresophisticated degree of technology to manage high energy levelsthrough the valve. The SteamForm valve design is customengineered inside and out resulting in a valve that is optimized forthe application. For high energy applications the valve body andoutlet are custom configured ensuring flow velocities areacceptable through the entire desuperheating system.

T

he management of pressure reduction and volumetric expansion

required in high energy steam flows is often accomplished withthe use of multiple diffusers. This approach creates a series of gradualexpansion areas as the steam transitions to outlet conditions. Theadditional diffusers create back pressure, reducing the amount ofpressure drop that is taken across the controlling surfaces of the trim.This minimizes the amount of wear on the controlling surfaces,protecting the shut-off integrity and further ensuring long term, accuratecontrol performance.

For top tier noise reduction V-LOG energy management trim is

utilized. This trim design gradually reduces the steam pressure bydirecting the fluid through a series of 90 degree turns in all threedimensions, combined with contractions and expansions in the flow

area. SteamForm valve designs can be engineered to include morethan 40-stages of V-LOG trim pressure reduction.

SteamForm Patented Desup

Desuperheating

The Masoneilan desuperheater is designed to reduce thesteam temperature by precisely injecting a finely atomizedmist of water into a highly turbulent mixing area.

Variable Orifice Spray Nozzles

Masoneilan achieves a wide range of control by using variable orifice,spring loaded spray nozzles. During low-flow operation, the Masoneilanspring loaded nozzles introduce a fine aerosol spray of water into the steam

line by slowly easing the nozzles off the seat. This provides properatomization of the spray water, even at minimal process flow. As the flow rateincreases, the water pressure lifts the nozzle plug further off the seat andopens the orifice to provide a full conical spray pattern. Masoneilan springloaded nozzles can provide Cv ratios in excess of 50:1.

The Masoneilan spray nozzleassembly design uses an easy toaccess, outlet area water injection

system for low cost and ease ofmaintenance over the life of the valve.Locating the water injection systemdownstream of the trim eliminatesunnecessary thermal stress on thevalve trim, and reduces the complexityof the parts that are critical foroperation. The SteamForm valvedesuperheating system providesreliable simplicity for technicallydemanding applications.

rheating Technology

Flow Profiler

The patented Flow Profiler has been designed tomaximize temperature control performance and toprotect the surrounding piping system from thermalstress induced by injection of cold water into hot flowingsteam.

Using time proven technology, the Flow Profiler isdesigned with all nozzles located inside the steamline. However, the nozzles are positioned so theirprotrusion into the process fluid is minimal. By injecting

the water from nozzles located in close proximity to thepipe wall, thermal shock to the desuperheater is greatlyreduced, as the desuperheater is no longer subject tothe dramatic temperature swings which are locateddeep within the center of the process stream.


Flow Profiler Technology

Masoneilan Desuperheater withOptional Lo-dB Plate

Stand-alone Desuperheaters

The Masoneilan desuperheater utilizes proven technologyof the SteamForm valve. The patented Flow Profilertechnology reduces the length of downstream pipingrequired for the temperature control sensor installation. Thepatented Flow Profiler further reduces the thermal stress onthe surrounding piping system by moving the process flow

heat transfer area to the center of the pipe away from thepipe wall.

For installation flexibility, the desuperheater is availablewith flanged or welded end connections. The design is also available with an optional in-line diffuser, which generatesa more turbulent flow pattern breaking up high velocity steam jets. Due to the simplicity of the design, and no movingparts, the desuperheater can be installed in either a horizontal or vertical orientation.

The desuperheater technology allows for reduced thermal stress, and improved process and temperature control forin-line desuperheating systems.

SteamForm High Efficiency

High Rangeability

Many applications use steam conditioning valves tothrottle across a wide range of operating conditions.For instance, many installations require theSteamForm valve to throttle at start-up conditionsas the plant comes on line and continue to controlas pressure builds up to the plants maximumcapacity. Startup duration may be prolonged andcan require the SteamForm valve to control atupwards of 50:1 rangeability over this time span.For these applications Masoneilan uses 2-active

stages of pressure reduction to properlymanage the energy letdown, whilepreventing excessive noise andvibration across the wide range ofconditions.

Thermal Cycling

Thermal stress in a process system can lead to severe

damage including sticking of the control trim, prematurewear of the valve, and even cracking of surrounding piping under

extreme temperature swings. Masoneilan uses a hung cage designto allow for free trim component expansion within the valve. This

design relieves the control valve trim of excessive thermal stress (themass of the cage absorbs the heat from the steam and expands).

The key to this design is allowance for unrestrictive expansion along theaxis of the plug. This axial expansion prevents excessive friction on themoveable parts such as the valve plug. As a result, smooth and accurate control

is provided under severe temperature conditions.

erformance

Long Term Shutoff

The SteamForm valve achieves tight shutoff consistent with ANSI/FCI Class IV and Class V leakage, as well as MSS-SP-61. Masoneilan considers this specification as one of the most critical for many applications including turbinebypass, as steam leakage will directly impact the efficiency of a plant.

To ensure long-term shutoff integrity, the Masoneilan SteamForm valve provides a design which seats upstream of theactual flow restriction area. Any condensate that may find its way into the system will flash downstream minimizingdamage to critical seating surfaces. Tight shutoff maximizes throughput to the steam turbine and other steam consumingequipment.

Fast Response & Precision Control

The Masoneilan SteamForm valve can be accessorized for fast opening (less than 1 second) in response to a turbinetrip to protect the turbine from undesirable conditions during either start-up or an upset condition. The SteamFormvalve will allow the steam in the system to bypass the turbine and cycle through the plant as if it were on line duringnormal operation. The undesirable alternative would be to trip the safety valve and vent the steam to atmosphere.

The addition of the Masoneilan SVI II AP digital positioner to the SteamForm valve provides extreme control accuracy

with best-in-class response to the slightest change in input signal. This combination results in reduced plantdowntime and improved bottom line return.

Power Industry Designs

The variations across industries and application specific operatingconditions make customization a necessity for steam conditioning.The SteamForm valve design can be engineered in both angle andglobe style configurations, as well as in both cast and forged bodyconstruction. This FLEXIBILITY allows Masoneilan to customize eachvalve specifically to fit our customers needs.

Power Industry Designs

Many power industry applications pose greater steam conditioningchallenges due to extreme conditions. Todays plants are operatingat higher pressures, higher temperatures, and are continuously cyclingon/off each day. Extreme duty cycling can be very demanding on anysteam conditioning valve. Masoneilan offers an upgraded body design tofit high-end trim solutions for these applications.

As a high end solution the SteamForm valve can be designed as arugged piece of equipment to withstand the cyclical nature of todayspeaking plants. The SteamForm valve is available in a forged bodyconstruction to absorb the rigors of these plants. In addition, anexpanded body gallery accommodates high end options such as the freeexpanding hung cage construction (thermal cycling) or V-LOG trim.

The SteamForm valve is ideally suited for large pressure dropapplications such as turbine bypass, that result in a large reductionin the steam density. Each SteamForm valve body is engineered toaccept custom connections and an enlarged outlet, so that the changein steam density does not result in an excessive velocity profile at anypoint within the valve. Further, each design is customized with the idealnumber of water injection points (spray nozzles) and the proper amountof water injection to accuratelycontrol the downstreamtemperature.
