The invention has the beneficial effects as follows: the present invention has the heating furnace of energy-saving and emission-reduction function after installing the high-energy radiation cover that is covered with the water conservancy diversion hole additional; The proal while of flame; The outer air communication of high-energy radiation cover is crossed the water conservancy diversion hole and is inhaled in the cover, has prolonged the time of staying of combustible; Form the crossflow disturbance, the liquid form of gas mixture becomes turbulent flow by direct current, produces turbulence effect, and fuel and air are more fully mixed, and has optimized combustion conditions, has promoted the efficient burning of fuel and realization to burn.
Description of drawings
Fig. 1 has the front view of the heating furnace of energy-saving and emission-reduction function for the present invention;
Fig. 2 is the left view of Fig. 1;
The structural representation that Fig. 3 launches for high-energy radiation cover of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
Shown in Fig. 1 to 3; Said heating furnace with energy-saving and emission-reduction function comprises support 9 and is arranged at the heating furnace cylindrical shell 6 on the said support 9; The inwall of said heating furnace is provided with furnace wall, and said heating furnace barrel has the radiation chamber 1 and convection cell 2 that is arranged side by side, and the inside of said radiation chamber 1 and convection cell 2 forms the hollow burner hearth; Said radiation chamber 1 comprises a furnace wall and a circle radiating furnace tube 7 that is provided with around said furnace wall; Said convection cell 2 comprises a furnace wall and a circle convection tube that is provided with around said furnace wall, and said cylindrical shell 6 is equipped with burner 3 near the fuel inlet place, center of said radiation chamber 1 one ends, in the said radiation chamber 1 high-energy radiation cover 4 is installed; Said high-energy radiation cover 4 is fixed on the heating furnace cylindrical shell 6 through bearing 10, has a plurality of equally distributed water conservancy diversion holes 5 on the said high-energy radiation cover 4.Fuel oil sprays into from the radiation chamber front end through burner, and radiation chamber forms the combustion zone, said radiation chamber and combustion zone unification, and flow media absorbs the radiation chamber heat continuously in the radiating furnace tube; Said radiating furnace tube is positioned at said burner hearth, is provided with along the radiation chamber furnace wall, and is coiled pipe or spiral coil; Said convection tube is coiled pipe or spiral coil.Said radiation chamber rear portion is a convection cell, and the convection cell structure is made up of furnace wall and convection tube, and after the radiation chamber high-temperature flue gas got into convection cell, the high-temperature flue gas waste heat was absorbed by convection heating surface again.
The cross section of said high-energy radiation cover can be selected multiple shape, and is preferred square or circular.Said high-energy radiation cover is coaxial with burner.Said pod apertures hole dia is 20～40mm, and distance is 150～200mm between the adjacent water conservancy diversion hole.
Said high-energy radiation cover afterbody is provided with flue gas shunting baffle plate 8, and said flue gas shunting baffle plate 8 is taper.Said flue gas shunting baffle plate 8 is a pyramidal structure, and angle of taper α is 20 °～160 °.Said high-energy radiation cover is to be processed by multifunctional material or metal material.Said flue gas shunting baffle plate is to be processed by multifunctional material or metal material.The installation of high-energy radiation cover raises the high-temperature flue-gas in the burner hearth rapidly, and to the continuous emittance of boiler tube, the crude oil that flows in the pipe constantly obtains the heat that is increased with convection type to high-temperature flue gas, and crude oil temperature is fully improved with ultrared form.Through adding the flue gas shunting baffle plate at high-energy radiation cover afterbody, prolonged the time of staying of flue gas in radiation chamber, strengthen the heat exchange amount of high-temperature flue gas and boiler tube, reach the effect that reduces exhaust gas temperature.
The high-energy radiation cover is installed in the heating furnace body radiation chamber, and fuel passes through high-temp combustion therein.The high-energy radiation cover becomes powerful radiation source, and the combustion chamber of a brand-new burning situation and " impartial high temperature " has been brought up in its internal radiation, and fuel is burnt more fully.It externally changes into the infrared ray electric electromagnetic wave radiation by original visible radiation, gives boiler tube through infrared ray with heat radiation, has improved the thermal energy that receives of working medium.
After the high-energy radiation cover is installed; Fuel completing combustion in the high-energy radiation cover; Avoided the local accumulation of unburnt on boiler tube, when not reducing boiler tube heat absorption, avoided safety problem again, solved because of the nozzles serious problems that flame licks pipe of making a fire partially because of local incrustation, overheated initiation.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
