摘要
燃气内燃发电机组在高温高湿环境下运行效率下降显著,进气参数对燃烧反应与功率输出构成复合作用机制。针对德清分布式能源站夏季带载能力波动问题,构建包含温度、湿度与风量三变量组合的27组实验工况,开展燃烧效率、机械效率与整机热效率的响应测试。结果显示,低温中湿中风组合具备最佳能量转化能力,25℃/61%RH/1600 m^(3)/h条件下系统表现最优,燃烧均匀性、气缸充气密度与中冷器热交换效率显著提升,整机效率提升2.3个百分点。研究验证了进气系统结构优化与参数调控在提升运行稳定性与负荷响应能力方面的有效性,为分布式燃气系统的运行策略设计提供理论依据与参数边界。
Gas-fired internal combustion generator sets exhibit significant efficiency degradation when operating in high-temperature and high-humidity environments,with intake parameters forming a compound mechanism affecting combustion reactions and power output.To address the load-bearing capacity fluctuations of Deqing distributed energy station during summer operations,this study established 27 experimental conditions combining three variables—temperature,humidity,and air flow rate—to test the response characteristics of combustion efficiency,mechanical efficiency,and overall thermal efficiency.Results indicate that the combination of low temperature,medium humidity,and medium airflow delivers optimal energy conversion performance.Under conditions of 25℃/61%RH/1600 m^(3)/h,the system achieved peak performance with notable improvements in combustion uniformity,cylinder charge density,and intercooler heat exchange efficiency,elevating overall system efficiency by 2.3 percentage points.This research validates the effectiveness of structural optimization and parameter regulation in intake systems for enhancing operational stability and load response capability,providing theoretical foundations and parameter boundaries for designing operational strategies in distributed gas-fired energy systems.
