Polyamine Treatment in HP Steam System of an Ammonia Plant

3+ N. 2(3-23) Feed rates of about 5 times stoichiometric are required for good oxygen scavenging. For every 1 mg/L of oxygen feed about 5 mg/L of hydrazine. The excess will break down to ammonia in the boiler (equation 3-23) and may cause problems in copper condensate systems unless they are air free.

New Technology Will Recover Heat &Water from Flue Gas

Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.

Boiler – Fundamentals and Best Practices

Boiler Water Treatment Considerations. For prolonged boiler life, a water treatment program recommended by a water consultant is a must. Steam boilers are sensitive to even minor deposits on tube walls. Therefore, most feedwater treatment programs are oriented toward scale control. However, internal corrosion control cannot be ignored.


Apr 15, 2015 · Ammonia (NH3) is the most widely used volatile alkali because of its low cost, ready available and its stability at high temperatures 11. The objectives of any chemical treatment for a modern, safe and efficient thermal power plant are: To reduce corrosion of metals and equipments To avoid scale formation 12.
