Abstract: There are some fuzziness between boiler hidden danger and hidden danger symptom in boiler system. It is difficult to establish precise mathematical model to predict boiler hidden danger. A boiler hidden danger early warning and evaluation model based on fuzzy expert system and fault tree analysis is proposed. The model judges hidden danger symptom and alerts hidden danger. Safety, economy and other systematic evaluation of boiler are given. Important references of optimal system operation program are provided for managers. Finally, boiler hidden danger early warning and evaluation system based on B/S structure and WEB technology is designed and developed. System application results show that the accuracy of hidden danger early warning results is high. System evaluation results are reliable and effective.

Key words: boiler, early warning, evaluation, fuzzy, expert system, safety

摘要： 锅炉系统中安全隐患与隐患征兆之间具有一定模糊性，难以建立精确的数学模型预测锅炉安全隐患。提出了一种基于FES和FTA的锅炉安全隐患预警及评价模型，该模型通过模糊推理，判断安全隐患征兆，预警锅炉安全隐患，对锅炉系统进行安全性、经济性等系统评价，为管理人员提供最优系统运行方案的重要参考依据。最后，基于Web技术设计开发了B/S结构的锅炉安全隐患预警及评价系统，系统应用结果表明，安全隐患预警结果准确率高，系统评价结果可靠有效。
