The primary function of a boiler is to transfer heat from hot gases generated by the combustion of fuel into water until it becomes hot or turns to steam. The steam or hot water is then used in a variety of facility processes. Boiler feedwater often contains impurities, which impair boiler operation and efficiency. To improve feedwater quality and steam purity, as well as correct other problems caused by impurities, chemicals can be injected directly into the feedwater or steam. Chemical additives increase boiler efficiency, reduce fuel, operating and maintenance costs, minimize maintenance and downtime, and protect equipment from corrosion and extend equipment life.
