Abstract

ABSTRACT In this study, the boiler blowdown was systematically examined and, the risks that increase the energy loss was determined using the potential Failure Mode and Effects Analysis (FMEA) method. Risk priority numbers (RPN) were calculated for each potential risk. It was revealed that ‘Performing more blowdown than it is necessary’ has the highest priority score. Improvement opportunities were identified by using the tree diagram, which is one of the process improvement techniques. Three suggestions were developed, such as flash steam heat recovery, reduction of water conductivity using the reverse osmosis technique, and the use of both methods. Repayment periods were calculated for each investment. If the flash steam unit and reverse osmosis system are applied together, 113.5 KW/h energy can be saved. It has been demonstrated that the FMEA technique can be used in the investigation and reduction of energy loss. Graphical Abstract

用FMEA方法降低蒸汽锅炉排污能耗

摘要在本研究中，对锅炉排污进行了系统的检查，并使用潜在故障模式和影响分析（FMEA）方法确定了增加能量损失的风险。计算每个潜在风险的风险优先级（RPN）。据透露，“进行超出必要的排污”的优先级最高。通过使用树形图来识别改进机会，树形图是过程改进技术之一。提出了三个建议，如闪蒸热回收、使用反渗透技术降低水的电导率以及使用这两种方法。对每项投资计算还款期。闪蒸气装置与反渗透系统配套使用，可节约能源113.5KW/h。已经证明FMEA技术可以用于研究和减少能量损失。图形摘要
