Description
Technical Field
The utility model belongs to the technical field of the burner of the heating furnace, a distribution of air energy-saving burner is related to.
Background
The heating furnace is a main energy consumption device of an oil refining enterprise, and the burner is a key part of the heating furnace. The problems of optimizing air distribution, lowering nitrogen, improving the heat efficiency of the combustor and prolonging the service life of the combustor are always the subjects of the industry. The temperature of the refractory bricks of the burner rises sharply when the burner is burned, resulting in that the temperature of the peripheral area of the burner of the heating furnace is significantly higher than that of other areas. A series of problems of high temperature of furnace walls around the burner, large heat loss, high temperature of refractory bricks, short service life of the burner and the like are formed.
SUMMERY OF THE UTILITY MODEL
The utility model provides an overcome above-mentioned problem, provide a novel optimize air distribution energy-saving burner. The burner can reduce the temperature of the refractory bricks of the burner and the peripheral furnace wall plates, reduce the heat dissipation loss of the heating furnace, and adopt a novel air distribution mode; the service life of the combustor is longer; the temperature fields of the furnace wall plate and the steel structure are more uniform, and the internal thermal stress of the steel structure is reduced.
The technical scheme of the utility model:
an optimized air distribution energy-saving burner comprises an air inlet 1, a burner nozzle 2 of a pilot burner, a main fuel nozzle 3, a primary air inlet 4, a cyclone distribution disc 5, a burner refractory brick 6, a secondary air inlet 7 and a tertiary air inlet 8. The fuel gas is sprayed out through a fire nozzle 3 of the main fuel pipe and is mixed and combusted with primary air passing through a primary air port 1 and a cyclone distribution disc 5; the air volume adjusting device is arranged at the air inlet volume of the primary air, the secondary air inlet 7 and the tertiary air inlet 8 are both opened on the firebrick 6 of the burner, the outlet position of the secondary air inlet 7 is positioned near the inner flame of the flame sprayed out by the main fuel pipe nozzle 3, and the outlet position of the secondary air inlet 8 is positioned near the outer flame of the flame sprayed out by the main fuel pipe nozzle 3; the secondary air is subjected to heat exchange with the high-temperature combustor refractory brick 6 and then sprayed to the inner flame of the flame to support combustion, and the tertiary air is subjected to heat exchange with the high-temperature combustor refractory brick 6 and then sprayed to the outer flame of the flame to support combustion, so that the fuel is fully combusted, and the flame is rigid, powerful and not floating.
The cold air exchanges heat with the high-temperature refractory bricks through the secondary air inlet and the tertiary air inlet, so that the temperature of the refractory bricks is effectively reduced, the heat efficiency of the heating furnace is improved, and the service life of the burner is prolonged. The temperature of the refractory bricks of the burner is reduced, the temperature fields of the furnace wall plate and the steel structure at the periphery of the burner are more uniform, and the thermal stress in the steel structure is reduced. And processing secondary air and tertiary air channels according to design conditions after the refractory bricks are fired. The proportion of the first air, the second air and the third air of the burner is controlled by the size of the primary air hole, the secondary air hole and the tertiary air hole and the primary air inlet adjusting device.

Fig. 2 is a partial cross-sectional view of the present invention.
In the figure: 1. an air inlet; 2. a burner of a pilot burner; 3. a main fuel nozzle; 4. a primary air port; 5. a cyclone distribution plate; 6. a burner tile; 7. a secondary air inlet; 8. and a tertiary air inlet.
Detailed Description
The following is further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, an air distribution energy-saving burner mainly comprises an air inlet 1, a pilot burner nozzle 2, a main fuel nozzle 3, a primary air inlet 4, a cyclone distribution disc 5, a burner firebrick 6, a secondary air inlet 7 and a tertiary air inlet 8.
When the burner is used for combustion, secondary air and tertiary air are subjected to heat exchange through the refractory bricks of the burner 6 and then are injected into inner flames and outer flames of the burner in a high-temperature air mode to support combustion. The temperature of the refractory bricks after heat exchange can be obviously reduced, the temperature of the wall plates around the burner is reduced, and the heat efficiency of the heating furnace is improved. The reduced temperature of the refractory bricks increases the useful life of the burner.
The size and the number of the holes of the I, II and III points are determined according to the characteristics, the load, the fuel and other factors of each combustor. The burner is in the optimal combustion state.
