### Boiler Water Evaporation Calculation

Let's determine what the real value of the salinity the boiler water will have. We calculate the coefficient of evaporation of the boiler water. К e = A bw /(A mw *А) = 22/(2,0*1)=11. Thus, the feed water in the boiler is evaporated by 11 times. Accordingly, the concentration of cations and anions of strong acids increases 11 times. Learn MoreLearn More

### BLOWDOWN CALCULATION FOR BOILER | v p - Academia.edu

The blow down is the water removed from boiler to maintain the solids level in the boiler drum. This can be calculated as follows: E = Evaporation or steam generation rate. S = Amount of solids (ppm) B = Blow down (m3 / hr) C = Maximum permissible concentration of solid inside the boiler drum B = E x S (m3 / hr.) C–S %B= S C–S This formula Learn More
