摘　　要：随着我国“极地战略”的不断深入,对燃气轮机等舰船动力装置防冰研究提出了更高的要求。以往研究主要关注引气流动控制及仿真,对引气防冰计算和参数研究尚很少涉及。基于进气冷凝结冰原理相关热力学公式分析,本研究首先明确了引气防冰标准,提出了压气机引气加热计算方法。进而通过某气电厂重型燃气轮机引气加热温升和湿降数据对比,验证了本文提出算法的正确性。最后,选取某型25 MW级船用燃气轮机数据,预测得到了不同压损和湿度条件下所需的引气温升、引气比例和引气热功率。指出极限防冰条件下,最大引气比例在1.1%~2.4%之间、引气热功率在370~770 kW之间。相关研究成果对指导引气防冰系统设计具有重要参考价值。With the deepening of my country's“arctic strategy”,higher standards are being set for anti-icing research in gas turbines and other marine power systems.Previous studies have primarily concentrated on bleed air flow control and simulation,but the calculation and parameter analysis of bleed air anti-icing remain largely unexplored.This study began with an analysis of thermodynamic formulas related to the principles of intake air condensation and icing,clarifying the bleed air anti-icing standards and proposing a calculation method for compressor bleed air heating.The correctness of the proposed algorithm was verified by comparing the bleed air heating temperature rise and humidity drop data of a heavy-duty gas turbine operating in a gas power plant.Finally,data from a 25 MW marine gas turbine were used to predict the bleed air temperature rise,bleed air ratio,and bleed air thermal power required under different pressure loss and humidity conditions.The study indicates that under extreme anti-icing conditions,the maximum bleed air ratio ranges from 1.1%to 2.4%,while the thermal power of the bleed air falls between 370 kW and 770 kW.These findings provide valuable reference for guiding the design and implementation of bleed air anti-icing systems.
