我国小型工业燃油锅炉的油燃烧器大多为旋流式,由于其旋流强度较大,引起风油配合不甚理想,一般燃烧效率较差。又由于小型油炉的炉膛宽度较窄、高度低,采用旋流调风器常引起两侧墙甚至顶棚及炉底严重结焦。本文认为采用平流式燃烧器,除风油配合比较合理及耗电量较小外,尚有火矩较 Most of the oil burners of small-scale industrial oil-fired boilers in China are of the cyclone type. Due to the large swirling intensity, the oil-gas mixture is not ideal and the combustion efficiency is generally poor. Also due to the small furnace hearth narrow width, low height, the use of cyclone regulators often cause two side walls and even the ceiling and the bottom of a serious coke. This paper holds that the use of parallel flow burners, with the exception of wind oil with more reasonable and less power consumption, there are still more than the fire
