Direct Steam Injection Water/Liquid Heaters

Pick offers two standard models of steam injection water/liquid heaters - for constant or variable water flow rate demand.

 

Our Direct Steam Injection Heaters are delivered as a complete, compact system including all piping, valves and controls.  They can be easily customized to meet your plant specifications.

Constant Demand

The Pick Constant Flow Heater is used wherever a relatively constant flow of heated liquid at a precisely controlled temperature is required.

 

It is ideal when the flow rate is fixed or varies over a narrow span (3:1), or where variations in flow are gradual and on/off cycling does not occur.

 

 

Typical Applications Include:

CIP

Pasteurizers

Jacketed Kettles

Tank Filling

Tank Car Heating/ Washing

Slurries

Green Liquor Heating

Felt Showers

Boiler Feed Water

Reactor Vessels

Centrifuge or Filter Back Flush

Tempered Water

Retorts

Extruders

Sterilization

Liquid-to-Liquid Mixing

Condensate Mixing

Resin Bed Regeneration

How the Pick "Constant Flow" Heater Works:

 

1. Water (or water-miscible liquid) enters mixing chamber here.

 

2. Set controller to desired outlet temperature.

 

3. Modulating steam control valve is activated by the temperature controller.

 

4. Steam and liquid mix thoroughly within the heater body.

 

5. Heated liquid outlet.

 

Constant Flow Heater Technical Specifications:

Sizing Formula:

Steam demand (lb/hr)= 0.43 x flow(GPM) x ∆ T (ºF)

or

Steam demand (kg/hr) = 0.092 x flow(LPM) x ∆ T (ºC)

Example: 200 GPM x 50ºF temperature rise x 0.43 =

4,300 lb/hr of steam. You would require a 6X50-3

which has a maximum rated steam capacity of 5,000 lb/hr, and a maximum water flow rate of 230 GPM

with threaded connections (500 GPM with welded

flanged connections).

Heaters are readily available with cast iron, carbon steel, or 316SS.  Other alloys/materials available upon request. Water and steam piping is available in threaded or flanged construction.

Variable Demand

The Pick Variable Flow Direct Steam Injection Heater is designed to deliver hot water at a precisely controlled temperature over a wide range of water flows. It will also reliably supply hot water for applications with frequent start-stop cycles, such as hose stations.

 

The Pick Variable Flow Heater is ideal as a central utility heating system for multiple use points such as wash-down stations, and plant sanitation.

Typical Applications Include:

Multiple Hose StationsPlant SanitationCan ToppingCan Washing 

Filter Back FlushFreezer Belt DefrostingLaundriesIndustrial Process Water

Variable Flow Heater Technical Specifications:

How the Pick "Variable Flow" Heater Works: 1. Water (or water-miscible liquid) to be heated enters mixing chamber here. 2. Set controller to desired set point. 3. Pump circulates water within the system to prevent stratification of water during low-flow conditions or intermittent use. 4. Modulating steam control valve is activated by the temperature controller. 5. Steam and liquid mix thoroughly within the heater body. 6. During idle mode (no demand) the relief valve discharges added condensate as steam is admitted to maintain set point temperature. 7. Heated liquid outlet  

Sizing Formula:

Steam demand (lb/hr)= 0.43 x flow(GPM) x ∆ T (ºF)

or

Steam demand (kg/hr) = 0.092 x flow(LPM) x ∆ T (ºC)

Example: 200 GPM x 50ºF temperature rise x 0.43 =

4,300 lb/hr of steam. You would require a 6X50

which has a maximum rated steam capacity of 5,000 lb/hr, and a maximum recommended water flow rate

of 230 GPM when furnished with 3”water piping.

Variable Flow Heaters are normally used on water service and are offered with cast iron housings as standard. Piping, fittings, and valves are iron, bronze, and steel. Alternate alloys/materials are available upon request. Water piping 3" dia. and smaller is threaded. 4" dia. and larger provided with 125# FF companion flanges and fittings.
