In a gas turbine power plant, the lubrication oil must be hot enough for the turbine start-up where the unit is in standstill mode. Currently, the strategy to heat the lubrication oil of ANSALDO V94.2 gas turbine power plant is operating the units in turning gear mode or interval mode. However, these strategies cause to suffering the power plant from high power consumption rate and aging. In this study, an auxiliary portable heating system was added to the unit 5 of the MAPNA built MGT-70 (an Iranian version of V94.2) Aliabad Katoul-Iran power plant for increasing the lube oil temperature. Irreversibility, cost-effectiveness, and availability of the proposed heating system are studied by the concepts of exergy, economy, and reliability analyses, respectively. The result of the exergy analysis shows that by using the auxiliary portable lube oil heating system the exergy destruction decreases about 94.7% and 92.6% in comparison with turning gear mode and interval mode, respectively. The result of the economic analysis shows that the auxiliary portable heating system consumes less power rather than turning gear mode. Moreover, it is a cost-effective system which has no penalty and no non-profit production. Finally, the reliability analysis shows that the auxiliary portable lube oil heating system is a reliable tool during its lifetime.

停机状态下在Aliabad Katoul-Iran V94.2燃气轮机中使用辅助便携式润滑油加热系统的案例研究

在燃气轮机发电厂中,润滑油必须足够热才能在机组处于静止模式时启动涡轮机。当前,加热ANSALDO V94.2燃气轮机电厂的润滑油的策略是在旋转齿轮模式或间隔模式下运行机组。然而,这些策略使发电厂遭受高功率消耗率和老化的困扰。在这项研究中,向MAPNA建造的MGT-70(伊朗版本的V94.2)Aliabad Katoul-Iran发电厂的5号机组增加了一个辅助便携式加热系统,以提高润滑油温度。分别通过火用,经济和可靠性分析的概念研究了所提出的供暖系统的不可逆性,成本效益和可用性。火用分析的结果表明,与旋转齿轮模式和间歇模式相比,使用辅助便携式润滑油加热系统的火用破坏分别减少了约94.7%和92.6%。经济分析的结果表明,辅助便携式加热系统比旋转齿轮模式消耗的功率更少。而且,这是一个经济有效的系统,没有任何罚款,也没有非营利性生产。最后,可靠性分析表明,辅助便携式润滑油加热系统在其使用寿命期间是可靠的工具。而且,这是一个经济有效的系统,没有任何罚款,也没有非营利性生产。最后,可靠性分析表明,辅助便携式润滑油加热系统在其使用寿命内是可靠的工具。而且,这是一个经济有效的系统,没有任何罚款,也没有非营利性生产。最后,可靠性分析表明,辅助便携式润滑油加热系统在其使用寿命内是可靠的工具。
