What is condensate recovery system?

Condensate recovery is a process to reuse the water and sensible heat contained in the discharged condensate. Recovering condensate instead of throwing it away can lead to significant savings of energy, chemical treatment and make-up water. As hot water, for cleaning equipment or other cleaning applications.

How do you calculate condensate recovery?

Energy Calculations for Return Condensate

1. (hc – hm) = Energy Loss per Pound.
2. 44,000 lbs of steam = 44,000 lbs of condensate (90 percent Return) = 39,600 lb.
3. 39,600 lb x 157.33 (BTU/lb) = 6,230,268 BTU.
4. 6.230268 x \$15.30 = \$95.32 per hour.
5. \$95.32 x 8,760 (hours/year) = \$835,003.20 per year.

Which of the following is advantage of condensate recovery pump?

Condensate is an excellent source of feed water as it is relatively pure (compared to most water supplies) being condensed water vapor. Condensate can also be used as the hot process water to use the enthalpy for heating coils or heat exchange units.

What is CRS boiler?

TCRS – Thermax Condensate Recovery System comprises of Flash Vessel, steam operated condensate transfer pump and Atmospheric deaerator head for effective pumping and mixing of condensate along with flash steam and makeup water in feed water tank. We are achieving the feedwater temperature to the boiler at 90 Deg.

How high can steam push condensate?

Steam Condensate Lift using an On-Off Control Scheme This is enough pressure to lift the condensate 12 feet to a gravity return main.

How can I improve my condensate recovery?

In order to improve the condensate in the existing system, the steam traps play a very important role. The type of steam trap also plays an important role. If the steam traps function to their fullest ability then there will be an increase of condensate recovery by approximately 10%.

How much is a ton of condensate?

A general rule of thumb is that . 1 to . 3 gallons of condensate is produced for every ton-hour.

How does a condensate return system work?

In a pumped condensate return system, the flashing condensate is discharged into a vented tank, from which the flash steam is removed. The condensate must be pumped from the vented tank to the collecting tank, and then pumped from the collecting tank to the boiler.

What are the benefits of recovering condensate?

Benefits of Condensate Recovery

• Significant savings on energy costs.
• High boiler feed water temperature minimises dissolved oxygen and therefore helps prevent corrosion.
• Reduces the total dissolved solids (TDS) in the boiler feed water.
• Minimises the need for makeup water and associated costs.

What chemical is fed to the deaerator?

Chemical Deaeration Equipment manufacturers state that a properly operated deaerating heater can mechanically reduce the dissolved oxygen concentrations in the feed water to 0.005 cc per liter (7 ppb) and 0 free carbon dioxide. Typically, plant oxygen levels vary from 3 to 50 ppb.

How hot is steam condensate?

Significant fuel savings occur as most returned condensate is relatively hot (130°F to 225°F), reducing the amount of cold makeup water (50°F to 60°F) that must be heated. A simple calculation indicates that energy in the condensate can be more than 10% of the total steam energy content of a typical system.

What happens when a steam trap fails?

Failed traps will prevent proper operation of sensitive equipment. When steam traps fail in a closed position, over time, the stagnant condensate will turn to carbonic acid (co3). In some cases water hammer can occur when a portion of the steam condenses into water within steam piping.
