Product overview

Boiler control and systems

An extensive range of boiler controls and systems are available. Whether it’s a completely new boiler house plant or a simple blowdown valve replacement, Spirax Sarco will have the answer.

1. Feedtanks The Spirax Sarco feedtank is an atmospheric deaerator fully constructed in stainless steel - no rusting, no linings, coatings or joints to leak. It is fitted with a flash condensing deaerator head which combines: cold make-up, condensate return and flash recovery. Flash steam is condensed whilst heating and deaerating the cold make-up.

4. Steam injection systems Steam injection systems can be used to inject steam into feedtanks to drive off the dissolved oxygen. This reduces the amount of oxygen scavenging chemicals required, and maintains a high and steady feedwater temperature to the boiler. 5. Level controls and alarms Significant developments have taken place in recent years considerably improving the standards of safety and reliability of boiler level controls. Probes without moving parts and modern electronic controllers are so reliable that major boiler accidents should be a thing of the past. The range offered has been approved as complying with the relevant Codes of Practice and European regulations. 6. Feedpump check valves Feedpump check valves are fitted with heavy-duty springs and soft seats to prevent a shutdown boiler from flooding with feedwater.

1.5 10

The deaerator head is also available for fitting into existing feedtanks.

2. Boiler blowdown systems As steam forms it leaves behind impurities in the boiler water that will concentrate unless removed. The TDS (Total Dissolved Solids) in the boiler must be accurately controlled. High TDS can result in carryover of boiler water and impurities causing problems with production and plant. Low TDS due to too much blowdown increases fuel and water treatment chemical costs. Systems are available for all sizes and types of boiler.

3. Sample coolers To be sure that a boiler is operating at the desired

concentration of TDS it is necessary to take a sample of the water and test it. The stainless steel sample cooler lets the operator do this safely and accurately.

spiraxsarco.com spiraxsarco.com spiraxsarco.com

7. Heat recovery systems Flash steam recovery from blowdown has two advantages. In addition to the heat recovered the flash steam is condensed to ‘pure’ water, reducing the amount of make-up water and chemical treatment required. For certain conditions it may be more economical to pass the blowdown directly to a heat exchanger without using a flash vessel. Spirax Sarco can provide a range of alternative heat recovery solutions. 8. Bottom blowdown valves For the precise and regular control of precipitated solids in steam boilers. A choice of manual key operated or fully, automated valves are available. 9. Vent heads The vent head separates condensate from flash steam and vents it safely without spray. Vent heads are manufactured in stainless steel for a corrosion resistant long life.

10. Blowdown vessels Blowdown vessels are now manufactured to ASME VIII to allow operation to an ambient temperature of -10°C. 11. Conductivity meters The temperature compensated conductivity meter is an essential instrument to have in the boiler house for checking boiler water and feedwater TDS levels, and calibrating control instrumentation. 12. Condensate contamination detection systems Even low levels of contamination can cause foaming, scaling and corrosion in the boiler. The contamination detection system monitors the conductivity of the condensate and will raise an alarm and divert it to drain if a pre-set limit is passed.

DH Type Flash Condensing Deaerator Heads

A simple low cost solution for deaerating boiler feedwater at atmospheric pressure - Mixes hot and cold incoming flows - Liberates oxygen and other gases - Stainless steel for long maintenance free life - Easy to install

2.1 1

Description Spirax Sarco flash condensing deaerator head is designed to mix incoming flows of cold make-up, condensate return and flash steam to the boiler feedtank. This mixing action is achieved by directing the downward flow through a baffle arrangement within the unit. This liberates dissolved gases from the cold make-up, which are vented to atmosphere. The cold make-up inlet is fitted with a spray screen which diffuses the flow, increasing its surface area to promote thorough mixing with the condensate and flash steam. A Spirax Sarco flash condensing deaerator head consists of three parts: - A mixing unit, which is bolted to the top of the tank and is supplied with connections to customer specification for cold make-up, condensate return, flash steam from blowdown etc. - An immersion tube, which distributes the mixed fluids into the tank and has an integral plate flange which is sandwiched between the tank and mixing unit flanges. Immersion tubes are fully described in separate literature. - Gaskets. Two gaskets are required, one fitted each side on the immersion tube flange. They are ordered separately. Available types The mixing unit is available in five nominal diameters (DN150, DN200, DN250, DN300 and DN400) flanged to EN 1092 PN16 or BS 7076 Class 150. Immersion tubes are available in diameters to suit the deaerator heads and lengths of 950, 1200, 1600 and 2100 mm to suit TM metric feedtanks. Since each deaerator head is built to suit specific plant requirements we recommend that your local Spirax Sarco Engineer is contacted for a connection layout sheet and to discuss your requirements.

Application Spirax Sarco flash condensing deaerator heads are ideal for boiler feedtank applications. They are suitable for both new and retrofit applications. Each head is fitted with a connection for air vent and recirculating feedwater spray nozzle. The air vent is for the immediate venting of liberated gases (the connection should also include a vacuum breaker). For further details on the RFS recirculating feedwater spray systems see separate literature.

RFS1 and RFS2 Recirculating Feedwater Spray Systems

• Increases flash steam condensing capability • Improves thermal efficiency of the feedtank • Improves deaeration within the feedtank • Energy saving three speed pump Description The Spirax Sarco RFS1 and RFS2 recirculating feedwater spray systems are designed to provide additional flash steam condensing capacity on boiler feedtank applications. When the condensate return flowrate is high and the cold make-up flowrate is intermittent it is likely that valuable flash steam will be lost through the vent. To ensure that this flash steam is condensed it is often worthwhile to take feedwater from a relatively cool part of the feedtank and pump it to a spray nozzle. Approximately 20% of the feedtank content can be circulated per hour to provide this additional flash condensing capacity. By using a low energy pump the thermal efficiency of the feedtank can be improved. Application The RFS1 and RFS2 systems are specifically designed for use with Spirax Sarco flash condensing deaerator heads. The mixing unit of each head is fitted with a connection for the spray nozzle. System components System type Isolating valve Y-Type strainer Pump Spray nozzle

Installation For new applications

For new applications a specific connection should be incorporated into the feedtank design. This connection should be the same nominal size as the pump and should be positioned as near as possible to the bottom of the tank. The suction side isolating valve, strainer and pump should be positioned as near to the tank as possible whilst allowing access for operating the ball valve and removing the strainer screen. The discharge side pipework should be as short in length as possible. On RFS2 systems the discharge pipework should be reduced to 1" at the spray nozzle. The pump must be wired in accordance with The Electricity at Work Regulations, that is, using a direct on-line (DOL) starter fitted with a thermal overload plus local isolator. For retrofit applications Where no suitable spare connection is available it is recommended that the drain connection be utilised by fitting a 'T' piece as follows. It should be noted that the tank does not need to be drained to fit these pieces.

To recirculating pump suction

Caution For all applications the pump shaft must be horizontal, or slightly higher at the vent plug end to prevent premature wearing of the top bearing and shaft. Operation The pump should run continuously when the boiler(s) is on load. Water should flow through the pump at all times while the pump is running. Maintenance At convenient regular intervals it is recommended that the strainer screen is inspected and any debris removed.

IT Immersion Tubes

Description Spirax Sarco immersion tubes may be: - Connected directly to the pipeline, to distribute condensate into feedtanks. - Used with a mixing unit to form a flash condensing de-aerator head (not applicable to the IT100 unit). Note: A flash condensing de-aerator head can be used to mix flash steam (from a TDS control system), cold make-up water, and condensate, and sparge it into a feedtank. It is described in separate literature. Immersion tubes offer a much neater solution than traditional sparge pipes, and can reduce many of the problems associated with them, for example vibration, rusting, and waterhammer. Immersion tubes are suitable for both new and retrofit applications where the feedtank is adequately constructed and braced.

Available types Available as types IT100_, IT150_, IT200_, IT250_, IT300_, and IT400_ with an integral inside bolt circle sandwich flange to suit ANSI 150 or EN 1092 PN16. They are available in lengths to suit TM metric feedtanks. Other lengths can be made to special order. Immersion tubes are designated by IT followed by DN followed by length of immersion tube in mm. e.g. IT250-1600 is DN250 and is 1 600 mm long from the underside of the flange. It is suitable for a 2 000 mm deep tank.

Capacity - when used without a Mixing Unit (MU) * Gravity condensate (with 5% Flash) Pumped condensate

* For other quantities of flash steam the capacity may be determined pro rata i.e. for 10% flash capacity is half that shown.

As a general rule the size of an immersion tube should be at least one DN larger than the condensate return main. Important note: The above table is only valid for condensate, where the flash steam content has to be considered. When sizing an immersion tube for use with a de-aerator head, use the guidelines in the flash condensing de-aerator head TI. The DH/IT has a higher overall capacity as it is able to condense the flash steam content of the fluid before it enters the tank. We do not make a mixing unit to suit the IT100.

Limiting conditions PN2.5 rating. Suitable for condensate at up to 1 bar g, 120 °C.
