[Weekly Topic] What is the impact of the boiler flame center position on its operation? (6.13--6.20)

The position of the flame center can change due to human factors and other influences, and such changes in the flame center position affect both the heat transfer in the boiler and its safe operation. If the position of the flame center is too low, it may cause slag formation in the cold ash hopper ； The flame center is too high, which raises the flue gas temperature at the furnace outlet; this leads to slag formation on the convective heating surfaces at the furnace outlet as well as an increase in the wall temperature of the superheater ； When the flame center is offset to one side within the furnace, slagging occurs on the furnace wall on that side. Of course, sometimes, to adjust the steam temperature, the position of the flame center can also be changed manually.

In the boiler furnace, as the fuel burns and releases heat, heat transfer also takes place. Since different parts are in different combustion stages, the heat release intensity varies, which results in different temperatures in various areas of the furnace. The highest temperature point in the furnace is called the flame center, also known as the combustion center. The correct position of the flame center within the furnace should generally be at the geometric center of the plane corresponding to the average height of the burner. The position of the flame center can change due to human factors and other influences, and such changes in the flame center position affect both the heat transfer in the boiler and its safe operation.

1. The upward movement of the flame center can lead to incomplete vaporization and an increase in gas carryover； If it is moved downward or shifted, it can cause local high temperatures at the nozzle and on the wall surface, leading to slag formation. 2. Center. The correct position of the flame center within the furnace should generally be at the geometric center of the plane corresponding to the average height of the burner. The position of the flame center can change due to human factors and other influences, and such changes in the flame center position affect both the heat transfer in the boiler and its safe operation.

Of course, sometimes, to adjust the steam temperature, the position of the flame center can also be changed manually.

An offset flame center can easily cause slagging on the water wall. Typically, the burner nozzles can be tilted up and down within a certain range, with the purpose of adjusting the position of the flame center; this is mainly used to regulate the temperature of superheated steam and reheat steam.

Do you guys find it interesting to keep copying things over and over?

The position of the flame center can change due to human factors and other influences, and such changes in the flame center’s location have an impact on heat transfer as well as on safety considerations. If the position of the flame center is too low, it may cause slag formation in the cold ash hopper ； The flame center is located too high, which increases the temperature of the flue gas at the furnace outlet; this leads to slag formation on the convective heating surfaces at the furnace outlet as well as an increase in the wall temperature of the superheater ； When the flame center is offset to one side within the furnace, slagging occurs on the furnace wall on that side. Of course, sometimes, to adjust the steam temperature, the position of the flame center can also be changed manually.
