【Abstract】 This paper deals with the necessity of boiler water pretreatment,and the adverse effects of the scale. Some physical process of boiler water pretreatment have been summed up. Also the priniple and result of the technologies about thermal softening, magnetizing and electric energy treating have been general described. Their merits and demerits have been contrasted. The paper pointed out that the physical process have some advantaqges over chemical process. The developing direction of the boiler water protreatment was studied.更多还原
