内燃机夏季“高温病”的分析与解决方案

Analysis and Solution of"High Temperature Disease"Internal Combustion Engine in Summer

随着气候变暖,燃气内燃发电机组在夏季运行出力衰减甚至故障停机的问题频繁发生。对于一些能源服务公司而言,机组“高温病”亟待解决。通过对内燃机燃烧系统流程与原理分析,提出进风温度基本决定了混合气初始温度,为此可以通过冷却进风方式将混合气温度维持在高限值以下,这对于一些建筑通风管路复杂的既有项目,具有十分重要的现实意义。

With the warming of the climate,the problem of gas-fired internal combustion generator'sets'performance degradation or even failure and shutdown frequently occurs in summer.This"high-tem-perature disease"is an urgent issue for some energy service companies to resolve.By analyzing the process and principle of combustion system of internal combustion engine,it is proposed that the inlet air temperature basically determines the initial temperature of the mixture,and the mixture temperature can be maintained below the high limit value by cooling the inlet air,which is of great practical signifi-cance for the existing projects with complex building ventilation pipelines.
