Because modern high-pressure boilers evaporate several million pounds of water every working hour, the purity of feedwater circulating inside the boiler is essential. Chemical treatment reduces scale-forming materials and corrosive oxygen content. A Feedwater Evaporator can be used as an alternative method to chemicals by removing impurities through evaporating raw water with extraction steam. Most often, the purity of feedwater is achieved by chemical treatment.
Because support chemicals for water treatment can include caustics, sodium hypochloride, sulfuric acid or other additives, individual chemistry and storage requirements will dictate the level instrumentation selected.
