Abstract
The utility model relate to a burner fuel quantitative shunt system comprising a gear pump and a shunt valve block. A suction inlet port of the gear pump is communicated with a fuel supply main pipe, and a fuel outlet port of the gear pump is communicated with a fuel inlet port of the shunt valve block component. A fuel outlet port of the shunt valve block component is connected with a quantitative fuel jet nozzle or quantitative fuel jet nozzle nozzles, which can be two, three, or four. The fuel shunt system of the fuel quantitative shunt valve block can be used to improve fuel return quantity of the valve block, increase the fuel supply quantity in the fuel supply pipe of the gear pump, reduce the reduction range of the fuel temperature in the fuel supply pipe under the condition of low load, and guarantee the fuel temperature not lower than the atomization temperature. The burner fuel quantitative shunt system provided in the utility model has advantages of high automatic igniting reliability and good burning effect.
Description
Technical field
The utility model relates to the quantitative separate system of a kind of burner fuel oil.
Technical background
Present position formula is regulated heavy oil burner, and under low fiery state, the fuel flow in the high-pressure gear pump discharge fuel feed pump is less, to the nozzle the oil temperature descend more, thereby cause automatic igniting reliability reduction and efficiency of combustion to descend significantly, even can smolder.
The utility model content
Its purpose of the utility model just is to provide a kind of burner fuel oil quantitative separate system, has the high and good characteristics of combustion efficiency of automatic igniting reliability.
The technical scheme that realizes above-mentioned purpose and take; Comprise gear pump; Also comprise the flow divider block assembly, described gear pump intake is connected with the fuel feeding house steward, and its oil-out is connected with the oil-in of flow divider block assembly; The oil-out of flow divider block assembly connects quantitative atomizer, and described quantitative atomizer quantity can be 1 or 2 or 3 or 4.
Beneficial effect
Owing to increased the return-flow burner oil return, guaranteed the atomization temperature of fuel oil, thereby overcome the original technique defective to have the high and good characteristics of combustion efficiency of automatic igniting reliability.

The specific embodiment
Comprise gear pump 7; As shown in Figure 1; Also comprise flow divider block assembly 8, the suction inlet of described gear pump 7 is connected with the fuel feeding house steward, and its oil-out is connected with the oil-in of flow divider block assembly 8; The oil-out of flow divider block assembly 8 connects quantitative atomizer, and described quantitative atomizer quantity can be 1 or 2 or 3 or 4.
Described flow divider block assembly 8 comprises return-flow burner 6, normally open solenoid valve 5, normally closed solenoid valve 4 and electric heating tube 3; The oil-in one tunnel of flow divider block assembly 8 connects the oil return opening of flow divider block assembly 8 through return-flow burner 6; One the tunnel connects the quantitative atomizer 1 of 2 ﹟ through normally closed magnetic valve 4; Quantitative atomizer 1 oil return of 2 ﹟ connects the oil return opening of flow divider block assembly 8, and another road of the oil-in of described flow divider block assembly 8 connects quantitative atomizer 2 oil returns of quantitative atomizer 2,1 ﹟ of 1 ﹟ and divides two the tunnel; One the tunnel connects the oil return opening of flow divider block assembly 8, and one the tunnel connects the oil return opening of flow divider block assembly 8 through normally open solenoid valve 5.
This device mainly is made up of high-pressure gear pump, flow divider piece, fuel nozzle.By the fuel oil that high-pressure gear pump sucks, Fen Sanlu quantitatively shunts.One the tunnel be gear pump in oil return opening, the one tunnel is flow divider piece oil-feed port, the one tunnel is flow divider piece oil return opening.
Flow divider piece oil-feed port is equipped with quantitative atomizer (quantity can be 1 or 2 or 3 or 4), and a quantitative atomizer of oil return also is housed on its oil return opening.
The gear pump intake is connected with the fuel feeding house steward, and its oil-out is connected with the oil-in of flow divider piece, and the oil return opening of flow divider piece is connected from oil return opening with gear pump.
1 separate system characteristic
This system generally is used for the pressure type heavy oil burner that a formula is regulated.Compare with the pressure type heavy oil burner fuel system of position formula adjusting in the past, this system has increased fuel oil flow divider piece.On the flow divider piece, be provided with oil return opening, and quantitative fuel nozzle has been installed.
2 operation principles
As shown in Figure 1; The amount of fuel that the gear pump inlet sucks is Q, and the amount of fuel that quantitatively sprays through flow divider piece oil-feed port nozzle is Q1, is Q2 by the quantitative recirculating oil quantity of flow divider piece oil return opening nozzle; High-pressure gear pump be Q3 from the oil return opening recirculating oil quantity, the relation that then has following formula to represent: Q=Q1+Q2+Q3.So when Q confirmed, the amount of fuel Q1+Q2 and the high-pressure gear pump that are transported to the flow divider piece were complementary relationship from recirculating oil quantity Q3.After Q1 confirms, improve the amount of fuel that the flow divider fuel feeding enters the mouth like need, then improve flow divider piece recirculating oil quantity Q2 and get final product.
3 major functions
The major function of this system is after Q1 confirms; Increase high-pressure gear pump and be exported to the fuel flow in the flow divider piece pipeline; To reduce the temperature drop of heavy oil in flow process after heating, guarantee that the heavy oil temperature that gets into burner noz(zle) is not less than its atomization temperature, guarantees the atomization quality of fuel oil.
After this system adopts, can make the fuel oil temperature in the pump discharge fuel feed pump of 2m～3m length promote about 20 ℃.
