Abstract

PURPOSE:To realize improvement of duration of a burner and stabilization of its combustion by regulating a ratio of primary air amount to a total amount of combustion air and an oil atomizing angle. CONSTITUTION:Oil is jetted from an oil gun 41, combustion air for this oil is divided into primary air and secondary air, and the primary air is swirled when it is supplied. In this case, it is regulated that a ratio of oxygen amount to combustion air amount is 21 to 60%, a ratio of primary air amount to all combustion air amount is less than 60%, and an oil atomizing angle of the oil gun 41 is less than 10 deg.. As a result, a long and stable flame of high temperature can be obtained. By this, inspite of an oxygen-rich oil combustion, rising-up of heating temperature of a burner 40 can be prevented, and clogging of the oil gun 41 due to burning damage and cabonization of oil can also be prevented.

2. Description of the Related Art In a steel mill, an oil burner that uses oil such as heavy oil as a fuel is used for heating a ladle and a scouring vessel after discharging molten steel to a high temperature and for cleaning. Oil is cheaper than gaseous fuel, and the equipment cost required for piping etc. when burning a large amount on an industrial scale is also low.

When a large amount of oil is burned on an industrial scale, it is general that an oil gun ejects fine atomized particles from the tip of the gun by an atomizing medium such as compressed air and water vapor. Here, when the oil spray angle is small, it is difficult to atomize the sprayed oil particles, and it becomes difficult to perform good combustion and the flame shape deteriorates. Therefore, the oil spray angle is often 25 to 55 degrees.

However, when the oil spray angle is increased in the oil burner, the sprayed oil particles spread in the vicinity of the burner and the flame becomes shorter. As a result, the burner and its oil gun become hot, and the burnout of these becomes significant. In addition, when the temperature of the tip of the oil gun becomes high, the oil is carbonized, and the gun is easily blocked.

When the fuel is a heavy flame-retardant oil such as tar, it is more preferable to provide the crater portion 30 with the wide-angle portion 31 and the narrow-angle portion 32. At this time, the combustion gas is the narrow-angle portion 31 of the crater portion 30. The corners 32 are sequentially passed. Since the front narrow-angle portion 32 has a smaller inclination angle than the rear wide-angle portion 31, the combustion gas is absorbed by the wide-angle portion 3.
Stand at 1. Due to this stagnation, the crater portion 3 of the swirled fuel
0 Adhesion to the wall surface is prevented and combustion continues stably.
The angle of the wide-angle part 31 is 20 to 90 degrees, the angle of the narrow-angle part 32 is 30 degrees or less, and 5/8 to 7/8 of the angle of the wide-angle part 31 is preferable.

On the other hand, the secondary air is directly ejected from the air ejection port 24 into the furnace. Here, the air ejection port 24 is closed at a plurality of positions in the circumferential direction by the filler 23. Therefore, the secondary air ejected from here is in a state of being divided in the circumferential direction, and the high heat in the furnace is introduced inside the secondary air flow through the divided portion, that is, the low pressure portion corresponding to the arrangement position of the filler 23. The gas flows in and promotes thermal decomposition and gasification of the oil. The filling material 23 is composed of the first cylinder 21 and the second cylinder 2.
Instead of interposing the two gaps in a closed manner, they may be intervened in a narrowed manner. In this case, the air ejection ports 24 have a series of current states in which the opening area is reduced at a plurality of positions in the circumferential direction. Is formed.

FIG. 4 is a graph showing the relationship between the ratio of the primary air amount to the total combustion air amount and the flame length when oxygen-enriched oil combustion was performed under the conditions of Table 1. A longer flame is achieved when the ratio of the primary air amount is 60% or less. However, if the amount of primary air is extremely reduced, particularly in heavy oil such as tar, the mixed gas of primary air and spray oil becomes insufficient, and ignition stability deteriorates. Therefore, the ratio of primary air volume is 15%
The above is desirable.

FIG. 5 is a graph showing the combustion stability when the amount of oxygen in the combustion air and the oil spray angle are changed using the same fuel A as in FIG. When using oxygen-enriched combustion air, it is better to make the oil spray angle smaller, and if the angle is 10 degrees or less, stable combustion with less oil gun blockage and oil adhesion to burner tiles is performed. This is because the flame becomes longer and the heating of the burner, in particular, the heating of the tip of the oil gun is suppressed by reducing the oil spray angle. Further, even if the oil spray angle is reduced, the atomization of oil and the flame shape are not particularly deteriorated. This is because the primary air is given a strong swirl so that the mixing property is good. Further, in this embodiment, the filler 23 is provided at the secondary air ejection port 24. It is also because hot gas in the furnace flows in, which promotes thermal decomposition and gasification of oil.

As is apparent from the above description, the oxygen-enriched oil combustion method of the present invention provides oxygen by defining the ratio of the primary air amount to the total combustion air and the oil spray angle in the oil gun. Despite the enriched oil combustion, the heating temperature of the burner is suppressed, the burnout of the burner and the blocking of the oil gun due to carbonization of the oil are prevented, and the durability of the burner is improved and the combustion is stabilized.
