摘　　要：基于涡轮增压机组与增压锅炉匹配工作两者之间存在的热平衡关系、压力平衡关系,以及涡轮增压机组内部存在的功率平衡关系,考虑机组管路系统的阻力特性和边界条件约束等,采用集中参数法给出了增压机组与增压锅炉两者配合工作的联合工作方程组,建立了适用于研究两者工作匹配特性的热力平衡计算模型,提出了一种迭代求解计算方法。在此基础上,通过仿真试验与机组主要测试数据的对比分析,证明了计算方法的可行性,以及建立的模型的正确性和有效性。还进一步研究分析了海况环境进气温度条件变化对两者的热力配合特性的影响。本研究为建立和掌握增压锅炉装置涡轮增压机组与主锅炉的热力匹配设计方法奠定了一定的理论基础。Based on the thermodynamic and pressure balance relationship between a supercharged boiler and its turbocharged unit,both of which are matched and work together,and on the balance relationship of the power output existing inside the turbocharged unit with due consideration of the resistance characteristics and restriction by the boundary conditions of the pipeline system of the unit,by using the centralized parameter method,presented were a joint equation group controlling the matching of the supercharged boiler and its turbocharged unit.Furthermore,a thermodynamic balance model controlling their matching characteristics was established and an iterative solution-seeking calculation method was presented.On this basis,through a contrast analysis of the simulation test data with the main measured ones of the unit,it was proven that the calculation method in question is feasible and the model thus established is correct and effective.In addition,the influence of the change of the inlet temperature under the sea conditions on their thermodynamic matching characterisitics was studied and analyzed in detail.The research findings have laid a certain theoretical foundation for formulating and grasping the mthod for thermodynamic matching design of a main boiler and its turbocharged unit in a supercharged boiler unit.
