Since water impurities cause boiler problems, careful consideration must be given to the quality of the water used for generating steam. The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler design.

Testing Boiler Condensate. Steam condensate is like money in the bank for boiler owner-operators. It has already been purchased and treated, making it most desirable for reuse as feedwater. The more condensate returned to the boiler, the less make-up water needed. Its heat content, when recycled back to the boiler, generates energy savings.

In this case, the amount of continuous blowdown is 10% of the amount of steam produced by the boiler. Let's calculate the salinity of the boiler water using the conversion factor (n) equaling to 0.5. S bw = 7798*0,5=3899 mg/l. Next, we will calculate the percentage of …
Read MoreBoiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.
