    BOILER COAGULANT prevents the formation of adherent deposits and sledges in boilers and thereby reduces clean-downs. Dosing Instructions Normal dosage is 20ml daily/tonne of boiler water capacity. Typically this equates to 0.1-0.3 litres/day. This is the recommended initial dose.Learn More

  • How do you calculate Boiler HP dosing system capacity

    Jul 21, 2020 · 1. Boiler capacity, operating pressure & temperatures be 100 TPH, 110 kg/cm2 & 530 deg C respectively. So phosphate dosing in mg/liter or ppm = 0.85 X 106 / (100*1000 X 24) =0.35. So per hour we have to dose (0.35 X 100 X 1000) / 1000 =35 gram of TSP into steam drum.Learn More

  • Boiler Chemistry Control and Treatment of Feed Water

    May 05, 2015 · Two types of AVT are; i) AVT (R) Using Ammonia (NH3) and as reducing agent like Hydrazine (N 2 H 4 ), ii) AVT (O) same as AVT ® minus reducing agent i.e. N 2 H 4. Ammonia is commonly used cheaper material to maintain pH in boiler water. N 2 H 4 is used to scavenge Dissolved Oxygen and protect Copper alloys from Ammonia.Learn More

    12. Boiler room layout and number of boilers. The dosage of sodium sulfite or other oxygen scavengers may be calculated by looking at their reaction rate to remove the oxygen and then their residual dosage to provide a feedwater or boiler water residual. Sodium Sulfite Example The reaction rate is: 2Na 2SO 3 (7.88 ppm) + O 2 ( 1 ppm) o 2Na 2SO 4Learn More

  • What is Carryover | Causes of Carryover - Leaders in Steam

    It can be practiced only when the drum size is big as in an oil-fired boiler with internal furnace. In external furnace cases, the steam space is less, thus feed water regulation would give purer steam. 9. Improper Chemical Dosage. A good water treatment is important to keep a check on carryover. Excess chemical dosage upsets boiler water Learn More
