一、前言 水煤浆与油、瓦斯相比,在燃烧性能方面存在着潜在问题:诸如水煤浆雾不易着火,火焰温度和释热率低;火焰不易稳定和燃烧不易完全等。虽然目前水煤浆已能在工业锅炉中燃烧,但上述这些问题仍是水煤浆燃烧的主要问题。 为了稳定燃烧往往采用旋转气流或不良流线体的方式。但对于水煤浆和低等级煤粉燃烧,这类方式可能不是太理想,还不足以解决上述的潜在问题。这主要是煤粒的燃尽时 I. INTRODUCTION Compared with oil and gas, coal-water slurry has potential problems in combustion performance. For example, coal-water slurry can not ignite easily, and the flame temperature and the rate of heat release are low. The flame is not stable and the combustion is not easy. Although coal-water slurry can be burned in industrial boilers at present, these problems are still the main problems of coal-water slurry combustion. In order to stabilize the combustion often use rotating airflow or poor flow body approach. However, for coal water slurry and low-grade pulverized coal combustion, this type of approach may not be ideal and not enough to solve the above potential problems. This is mainly when the burnout of coal particles
