How many pounds of anhydrous Trisodium phosphate (TSP) are used per 1000 gallons of feed water in the boiler boiling-out procedure?

In the boiler boiling-out procedure, anhydrous Trisodium Phosphate (TSP) is used to help clean and prepare the boiler for operation by removing contaminants. The standard practice for this procedure involves using 120 pounds of TSP per 1,000 gallons of feed water. This amount is calculated to ensure effective cleaning while maintaining the integrity of the boiler and associated systems. The TSP works by reacting with scale and other deposits, effectively breaking them up so that they can be flushed out, thereby helping to improve boiler efficiency and longevity. The selection of this specific quantity ensures that the cleaning process is thorough and meets operational standards for safety and performance.
