为了提高锅炉房运行效率,针对清华大学燃气锅炉房一次网母管制供、回水的情况,以实测锅炉数据的实矩阵为基础,利用最小二乘法和Householder变换进行分解,确定每台锅炉的燃料耗量特性方程,并利用Lagrange乘数法设计了3台锅炉任意组合运行时的锅炉房负荷分配方案。根据该分配方案,锅炉房可比每台锅炉平均分配负荷情况最多减少3%燃料消耗量。对该分配方案的分析表明,实行负荷优化分配必须在满足锅炉房总负荷要求下尽量少运行锅炉台数的基础上才能取得更好的效果。
In order to improve the operating efficiency of the boiler room, aiming at the primary network control of supply and return water for the gas boiler room of Tsinghua University, based on the real matrix of the measured boiler data, the least square method and Householder transformation were used to decompose the fuel of each boiler Consumption characteristic equation, and the Lagrange multiplier method was used to design the boiler room load distribution plan when any three boilers were operated in any combination. Under the distribution plan, the boiler room can reduce fuel consumption by up to 3% more than the average load distribution per boiler. The analysis of the distribution scheme shows that the optimal allocation of load must be based on the number of boilers operating as little as possible to meet the total load requirements of the boiler room to achieve better results.
