Summary of required Calculation For a boiler that uses make up water and blow down the calculation steps are as given below: 1. Estimate the blow down rate based on the COC and steam rate. 2. Determine phosphate required to maintain a level 30-60ppm of PO4 in the boiler based on the chemical loss due to blow down. 3.
