针对内燃式热风炉提高燃烧强度后产生的振动问题,从热风炉燃烧与压力特性角度,采用数值模拟方法进行研究,分析内燃式热风炉燃烧过程中的振动特性。研究表明:内燃式热风炉的振动属于低频振动,其振动是燃烧过程所导致;燃烧能力增加,燃烧室内压力波动振幅迅速增大,压力波动频率与实测频率相吻合,表明振动是因燃烧过程中的压力波动所导致。 Aiming at the vibration problem of the internal combustion type hot blast stove which enhances the combustion intensity, the numerical simulation method is used to study the vibration characteristics of the internal combustion type hot stove combustion from the perspective of the combustion and pressure characteristics of the hot blast stove. The results show that the vibration of the internal combustion stove belongs to the low frequency vibration and its vibration is caused by the combustion process. The combustion ability increases and the amplitude of the pressure fluctuation in the combustion chamber increases rapidly. The frequency of the pressure fluctuation agrees with the measured frequency, indicating that the vibration is caused by the combustion process The pressure fluctuations caused.
