Chemical Treatment Requirements for Steam and Hot Water

Jun 12, 2017 · What is a boiler? A boiler is simply a heat exchanger that uses radiant heat and hot flue gases, liberated from the burning of fuel, to generate steam and hot water for heating and process loads, including power generation. In a steam plant, the boiler is best defined as a vessel for the generation and enclosing of a vapor under pressure.

In the case of industrial process contamination, it is possible for organic contaminants to decompose under boiler temperature and pressure to form organic acids. Sugar is an excellent example of an organic which, when returned in a large quantity, can cause rapid loss of boiler water alkalinity and reduce pH of the boiler water to 4.3 and lower.
