Heat Recovery Unit

In most cases Boiler flue gases leave at considerable extreme temperature taking away valuable heat. This heat is recovered by putting in an easy Heat Recovery Unit (Water Pre-heater). This heat is utilized to heat the Boiler Feed Water.By installing an easy Heat Recovery Unit, fuel consumption is generally reduced by 4–6 %. Each five degree increase in feed-water temperature can offer an potency improvement of 125th. Heat Recovery Unit (HRU) may be a easy shell & tube type Heat ex-changer sized for: The volume and temperature of flue gases.

* Pressure drop across it
* Fuel utilized in the boiler
* Quantity of warmth to be recovered
* Properly designed Heat Recovery Unit (HRU) has the power to cut back the fuel needs of a boiler by transferring heat from the exit flue gases to the feed water. but flue gas cooling below Sulphur dew-point isn’t best for top sulphur fuels to avoid corrosion & erosion of apparatus.

    Benefits of Heat Recovery Unit

    • Heat Recovery Unit (HRU) Recovers Waste Heat From Flue Gases, Thereby Rising Potency Of The Boiler System.
    • Helps The Boiler To Supply A Lot Of Steam In Same Value.
    • Heat Feed Water Puts Less Strain On Metal As Temperature Differential Is A Smaller Amount Therefore Serving To In Extending Lifetime Of The Boiler.
