Title: Jet burner

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a burner, in particular to, a jet burner for sufficiently increasing the fuel burning efficiency. 
     2. Description of Related Art 
     According to prior art, the burner is widely used in a boiler, a heating furnace, a drying equipment and an industrial furnace and other thermal machinery, and the basic architecture of the conventional burner is shown as  FIG. 1 . The conventional burner is installed with a burning chamber  12  coupled to an air blower  11 , and interior of the burning chamber  12  is installed with a plurality of nozzles  13  coupled to a fuel providing device (not shown in the drawings). Mainly, the air blower  11  generates the accelerating gas fluid in the burning chamber  12 , and after the fuel injected into the burning chamber  12  is fired, accompanying the gas fluid in the burning chamber  12 , the fire can be spurted and burned at the front end of the burning chamber  12 . 
     The fuel of the conventional burner is mostly the diesel with good ignitability. Currently, there is also a burner provided as follows. After the burner utilizes a heater to heat the heavy oil to the high temperature of 110 degrees Celsius, the high-pressure pump transfers the heated heavy oil to the firing position via the pipeline, and thus the heavy oil can be the fuel. The most applications of the burners currently are applied thermal machineries and applied heat exchange devices, both of which are directly coupled to the front ends of the burning chambers  12  of the burners, and thus the increased efficiency is entirely determined according to the fuel burning efficiency and the reaction range of the fire at the front end of the burning chamber  12 . 
     Though the conventional burner utilizes the air blower to generate the accelerating gas fluid, in the actual application, the fuel injected into the burning chamber may be blew out from the burning chamber in the non-complete burning status due to the over-reaction of the accelerating gas fluid, such that the conventional burner cannot have the expected fuel burning efficiency.
