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 thermal balance relationship between the turbocharger unit and the booster boilers, the pressure balance relationship and the power balance existing inside the turbocharger unit, considering the resistance characteristics of the unit piping system and the boundary condition constraints, The method of collective parameter method is used to set up a joint working equation system which works together for booster and booster boilers. A thermodynamic equilibrium calculation model suitable for the work matching characteristics of both booster and booster boilers is established. An iterative solution method is proposed. On this basis, through the comparative analysis of the simulation test and the main test data of the unit, the feasibility of the calculation method and the correctness and effectiveness of the established model are proved. Further study and analysis of the impact of changes in the inlet conditions of the sea environment on the thermodynamic characteristics of both. This study lays a certain theoretical foundation for establishing and mastering the thermal matching design method of turbocharger unit and main boiler in pressurized boiler plant.
