EN 12952-12:2003,Water-Tube Boilers and Auxiliary Installations-Part 12:Requirements for Boiler Feedwater and Boiler Water Quality -A European Standard Put to the Test-

摘要

In December 2003,Part 12(Requirements for Boiler Feedwater and Boiler Water Quality)of the European Standard "Water-Tube Boilers and Auxiliary Installations" appeared.According to the Pressure Equipment Directive of the European Commission,this standard should ensure that the hazards associated with the operation of water-tube boilers are reduced to a minimum and that adequate protection is provided to contain the hazards that still prevail when the water-tube boiler is put into service.The standard is compulsory.Power plant chemists should keep in mind that non-compliance with this standard may have serious(legal)consequences.This contribution considers whether this standard actually addresses all safety-related parameters and whether it abstains from setting parameters that are not related to equipment and personnel safety.According to the Pressure Equipment Directive demands,parameters important for economics,availability and steam quality as well as those relevant to the operation of other cycle components should not be dealt with in this standard.
