摘要
热平衡计算是锅炉热力性能计算的关键。针对带涡轮增压机组做功的增压锅炉结构特点和工作特点进行分析和阐述,提出了考虑空气夹层吸热的船用增压锅炉热平衡及热损失的计算方法,给出了进入炉膛热量、各种损失、特别是增压机组热损失和保热系数的计算式,并对某增压锅炉有、无空气夹层的影响进行了热力校核计算,计算结果接近实际情况。本研究提出的计算方法可为船用增压锅炉热力性能计算提供参考。
Heat balance calculation is crucial for calculating the thermodynamic performance of a marine turbo-charged boiler.By performing an analysis and explanation in the light of the structural and operation features of a turbocharged boiler with its turbocharged unit doing work,the authors have proposed a method for calculating the heat balance and thermal loss of a marine turbocharged boiler with the heat absorbed by the air interlayer being taken into account,presented a formula for calculating the heat entered into the furnace and various losses,especially the thermal loss and heat isolation coefficient of the turbocharged unit and performed a thermodynamic check calculation of the turbocharged boiler with or without the influence of the air interlayer.The calculated results approximate to the actual conditions.The calculation method being proposed by the authors can provide reference for thermodynamic performance calculation of marine turbocharged boilers.
