Definitions

  • the discovery relates to heat-and-power engineering, and can be used in fuel combustion.
  • the objective of the invention is to save energy and to protect the environment.
  • a device which comprises a rod-shaped electrode connected to an alternating current source and a high-voltage pulse tension source [Russian patent no. 2058510, F24F3/16, published 20. 4. '96].
  • This type of oxydiser preparation makes it possible to increase the electronic emission and to obtain a gas discharge using an electrical tension of a few tens of kilowatts, instead of hundreds or thousands.
  • the nearest technical equivalent to the invention in question is a device which comprises a grid-shaped electrode, which is positioned in the oxydiser piping, and electrically insulated from the oxydiser piping walls [Ukraine patent no. 24193 A, F23C 11/00, published 7. 7. '98].
  • this device does not allow the desired depth of ionisation of the air (the oxydiser) and the desired uniform distribution of ionised particles across the oxydiser flow section to be obtained, or even the desired maximum intensification of fuel combustion.
  • the objective of the invention is to create an oxydiser preparation device for fuel combustion which could intensify the fuel combustion process as much as possible, and reduce the air feed level and the quantity of waste gases through the positioning of electric charge exhausters on the electrode grid, the pointed ends of which are orientated in the direction of movement of the oxydiser flow, which makes it possible to reduce the quantity of harmful substances ejected into the environment and to increase the efficiency of heating units.
  • a device for oxydiser preparation which comprises a rod-shaped electrode, positioned in the oxydiser piping and electrically insulated from the walls of the oxydiser piping.
  • the electrode grid is equipped with electric charge exhausters positioned at right angles to the grid floor;
  • the electric charge exhausters are preferably 60-120 mm. long;
  • the electric charge exhausters are tightly fastened by the blunt ends to the intersection units of the longitudinal and transverse conductors of the grid;
  • the pointed ends of the electric charge exhausters are orientated in the direction of the air flow movement.
  • An electric current of 20-25 kilowatts DC is applied to the grid-shaped electrode with the electric charge exhausters.
  • the charged grid creates a non-uniform electrical field in the airline, through which air is fed from the pressurised blower fan to the fuel burners of the heating unit.
  • the air As a result of the passage of the air through the electrical field, it is ionised.
  • the oxygen contained in the air, and used as an oxydiser during combustion is activated.
  • the activated charged particles of oxygen flow from the tips of the electric charge exhausters, and are uniformly distributed over the entire section of the oxydiser's mobile flow, are captured by them and taken away to the fuel device.
  • the degree of ionisation of the oxydiser is specified by the current leak level (cll), and depends on the height of the electric charge exhausters.
  • h 40 mm.
  • cll 3.5 ma h - 130 mm.
  • cll 3.4 ma
  • the actual reduction of the volume of oxydiser (air) leads to a reduction in heat losses through waste gases. And as a result of the fact that the amount of air fed into the combustion is reduced, there is a corresponding decrease in the quantity of smoke gases being led off into the atmosphere and as a result the heat loss is curtailed. Consequently, under unchanged conditions (from a percentage point of view), as regards the waste gases of harmful substances, their gross ejection into the atmosphere is reduced.
  • the fuel does not need to be heated up as much as would be necessary in normal circumstances to generate a unit of heat. All of this leads to an increase in the efficiency of heating units and, in sum, to a saving of fuel. The effect will be greater if the grid electrode is positioned directly in front of the fuel ignitor.
  • the drawing shows the device presented, set up in an airline.
  • the oxydiser preparation device for fuel combustion comprises a metallic electrode grid 1, set up inside an airline 2, separated from the walls of the airline 2 by continuous ceramic insulators 3. At the intersection points of the longitudinal 4 and transverse 5 electric charge conductors, electric charge exhausters 6 have been set up.
  • the electrical voltage on the electrode 1 is supplied by a power source 7 through the continuous ceramic insulator 3.
  • the proposed device works in the following manner.
  • Air containing an oxydiser is fed along the airline 2 into the fuel ignitor (not shown on drawing).
  • the oxydiser travels through an electrode which takes the form of a metallic grid 1, made up of longitudinal 4 and transverse 5 electric charge conductors, firmly fastened at the intersection points of the electric charge exhauster conductors 6.
  • An electric current of 20-25 Ka is fed onto the electrode 1 through a continuous ceramic insulator 3.
  • the grid becomes charged, and creates a non-uniform electrical field in the airline, under the influence of which the oxydiser travelling through the electrode is activated to generate atomic oxygen, and becomes a more powerful oxydiser than molecular oxygen.
  • the power of the rectifier used to obtain the essential current does not exceed 20 Watts.
  • Table 1 lists the comparative data which support the effectiveness of the electro-physical influence of the device presented and the prototype for fuel combustion.
  • Item no. Indicators Cherkass Instrument Making Plant (water heating boiler KV-GM-30) "Donyetsk Mettalurgical Plant” VAT (boiler BKZ-75-39-F5) 1 Operation of boiler with prototype ionisation device switched on: Efficiency of boiler, % 92.63 85.87 Specific natural gas expenditure, m. 3 /Gcal. 136.72 166.36 (kg. u. t./Gcal) Specific electrical energy expenditure on draught and blast, kilowatt hours/Gcal.
  • Table 2 lists experimental and calculated data if the temperature of the waste gases is reduced and the excess air ratio for the boiler if the prototype air ionisation device and the air ionisation device according to invention are switched on.

  • the device presented is capable of carrying out the fuel combustion process more intensely, due to a more intensive ionisation of the oxydiser, which makes it possible to reduce the expenditure of fuel in thermal power station boiler installations by a mean level of 0.5-1.5%, and in the boiler installations of thermal electric power stations for industrial plants by 2.5-3%; to increase the efficiency of thermal power station heating units by 0.5-1.0%, and of the heating units of thermal electric power stations for industrial plants by 2.0-3.0%, and to reduce the gross ejection of harmful substances into the atmosphere by a mean level of 8-12%.
  • the device presented is technically easy to manufacture, with the aid of known equipment, and using known technologies and accessible materials.
