Abstract

The invention improved combustion efficiency in an apparatus for adsorbing or removing foreign substances melted or contained in a fuel by adsorbing and removing combustion obstruction substances dissolved in a liquid fuel such as kerosine oil and light oil and the like, and adsorbing and removing lower high molecular substances contained in vaporized fuel. Lower high polymer substances being combustion obstruction substances contained in the liquid fuel are adsorbed and removed when the liquid fuel passes through the activated carbon, and for the vaporized fuel foreign substances and impurities are adsorbed with a filter comprising a stainless raw material mesh, and then injection is executed with the nozzle for combustion.

Description

The apparatus for adsorption and removing of foreign matter of the fuel gasifying combustion device of combustion chamber of boiler for warming rooms

Fig. 1 is a longitudinal section of the present invention.

Fig. 2 is a part exploded perspective view of the present invention.

Fig. 3 is the amplification sectional view of nozzle segment of the present invention.

Fig. 4 is the part amplification sectional view of filter of the present invention.

10 the expression nozzle housings, 11 the expression nozzles, 12 the expression grooves, 13 the expression filters, 20 the expression active carbons, 21 and 21a represent filter paper, 22 the expression filters.

When the present invention relates to the fuel gasification combustion in making the combustion chamber of boiler for warming rooms, the adsorbable device of removing the impurity in the fuel burning.More specifically relate to not only remove the impurity that is dissolved in the liquid fuel, but also absorption remove the device that is included in the rudimentary polymer substance in the gaseous fuel through gasification.

The combustion method of fuel comprises the mode that liquid fuels such as making kerosene and light oil directly burns in the combustion chamber in the combustion chamber of boiler for warming rooms, and the applicant is made the gasification, and combustion mode of its burning again by nozzle ejection after the heating fuel that No. 138539 record invented by Korea S makes its gasification.When liquid fuel is directly burnt, being included in impurities from fuel removes through filter, this is the method for removing solid impurity, but can not remove the chemistry impurity that is dissolved in the fuel, as rudimentary polymer substances such as heavy metal substance, tar, wax, sulphur, in combustion process, just become the main cause that hinders burning like this.And, be adsorbed in the nozzle bore as the components such as tar, wax and sulphur of unburned rudimentary polymer substance in the combustion process, cause efficiency of combustion to descend, this just becomes the main cause that shorten service life the combustion chamber.

In addition, when using gasified combustion apparatus, liquid fuel such as kerosene and light oil filters through filter, spray from nozzle in economizer bank gasification back, at this moment, though solid impurity is filtered by filter, but be dissolved in the chemical impurity in the fuel, be not removed as rudimentary polymer substances such as heavy metal, tar, wax and sulphur, in the process that fuel gasifies with this state inflow economizer bank, the material of various obstruction burnings is remaining, unburned, formed gel in the inwall that is adsorbed in economizer bank and nozzle, this just becomes the main cause that the economizer bank internal diameter diminishes.And, even they also can hinder burning by nozzle bore, and producing coal smoke, this just becomes the efficiency of combustion main reasons for decrease, so, can not be widely used.

Therefore, the objective of the invention is to improve efficiency of combustion, when the method that adopts is a fuel gasification combustion in making the combustion chamber of boiler for warming rooms, make liquid fuel by the active carbon filter layer to remove solid impurity and to be dissolved in fine rudimentary polymer substances such as sulphur, tar and wax in the fuel, again fuel is imported economizer bank, make fuel gasification change gaseous fuel at economizer bank, meanwhile remove the various impurity of generation and hinder the material that burns, spray into vaporizer at last with filter absorption.

The top of combustion tube 1 is provided with the gasification, and combustion pipe 4 with vaporizer 2, and its bottom is provided with burning regenerator section 5, combustion preheater part 5a and has the economizer bank 7 of injection nozzle 6.Connected injection nozzle 6 on the part that connects delivery pump 8 on the cartridge 23 and constitute, this injection nozzle 6 connects nozzle 11 and constitutes on nozzle housing 10, the filter 13 that stainless (steel) wire constitutes is housed in the groove 12 of nozzle 11, is to have inserted the filter 22 that possesses filter paper 21a before and after active carbon 20 constitutes at the rear portion of the delivery pump 8 of cartridge 23.

Unaccounted 30 expression heating wires among the figure.

Among the present invention, the liquid fuel of fuel bath is earlier by cartridge 23, again by filter 22, be dissolved in the sulphur of liquid fuel, tar, rudimentary polymer substance such as wax and impurity are by active carbon 20 and

filter paper

21,21a adsorbs and filters, then, utilize delivery pump 8 that fuel is transported to economizer bank 7, the liquid fuel that has been delivered to economizer bank 7 is by combustion preheater part 5a or 5 heating of burning regenerator section, be converted to gaseous fuel, flow to injection nozzle 6 again, when being in the various impurity that comprise in the gaseous fuel of vaporized state and becoming the solid matter of the main cause that hinders burning, utilize nozzle 11 to spray with filter 13 absorption.Promptly, the gaseous fuel that ejects by nozzle 11 earlier through be positioned at being filled into of liquid fuel pipe 23 filter 22 of active carbon 20 once filter, after rudimentary polymer substances such as tar, wax, sulphur are removed in absorption, then be converted to gaseous fuel at economizer bank 7, filter 13 with nozzle 11 filters the various impurity that produce once more simultaneously, spray into vaporizer 2 then, utilize gasification, and combustion pipe 4 to burn.

Because fuel filters with the filter 22 of liquid state through active carbon 20, after economizer bank 7 is converted to gaseous fuel, the filter 13 that constitutes through the stainless (steel) wire of nozzle segment filters and burns again, so, do not produce the material that hinders burning in burning point, as rudimentary polymer substances such as sulphur, tar, waxes, but so just completing combustion has improved efficiency of combustion.

As previously mentioned, the present invention makes liquid fuels such as kerosene in the combustion chamber of boiler for warming rooms, light oil earlier after the material of the various obstruction burnings that are dissolved in fuel is removed in the filter absorption that has been filled into active carbon, be converted to vaporising fuel by the economizer bank gasification, then, filter through being arranged at nozzle segment carries out secondary filter, removes the material that hinders burning.Owing in combustion process, do not produce the material that hinders burning, so, can not stop up economizer bank and nozzle, their internal diameter is diminished, the generation of coal smoke sharply tails off like this, increased substantially efficiency of combustion, also prolonged the service life of combustion chamber simultaneously, so be a kind of invention of great use.
