Abstract

PURPOSE:To efficiently remove iron oxide scale by contg. a citric acid, a reducing agent an alkylbenzenen sulfonic acid. CONSTITUTION:The titled scale dissolving and removing agent for boilers consists of a citric acid or its salt, a reducing agent, an alkylbenzene sulfornic acid or its salt. An l-ascorbic acid or its salt and deriv., an l-sorbic acid or its salt and deriv. are used as the reducing agent, and the amount of the use thereof is 0.01-0.1wt% in the scale dissolving and removing agent. The pH of this scale dissoling and removing agent is kept at 3-6.
