摘要: 摘要:针对火力发电企业实际燃用煤种繁多、煤质特性各异、锅炉燃烧不稳定以及经济性差等问题,构建了以燃煤成本最低为目标函数,以发热量、硫分、挥发分、水分、灰分等指标为约束条件的数学模型。在此模型基础上开发了燃煤掺配模拟系统,该系统能够根据锅炉对发热量、灰分、水分、挥发分、硫分的不同要求做出计算调整,给出满足锅炉稳燃要求的原煤混配方案。

Abstract: Abstract:In some thermal power generation enterprises, the practically fired coals are of various types, and the coal quality and characteristics are different, which causes unstable combustion in boiler and poor economic efficiency. Aiming at above problems, a mathematic model of raw coal blending was established. The goal function of the model is the lowest coal cost, and the constraint conditions of the model are the indexes of the calorific value, the sulfur content, the volatile component, the moisture and the ash content. Based on this model; a coal blending simulation system was developed. According to the requirements of boiler on the calorific value, the ash content, the moisture, the volatile component and the sulfur content, using the simulation system, a raw coal blending scheme can be obtained, which can meet the requirement of stable combustion of the boiler.
