Abstract

Abstract A perfect fuel gasification device for use in combination with a combustion apparatus in which there is provided a hollow cylindrical main body divided into a plurality of operation zones, an air or fuel conduit extending from and in fluid communication with said main body, fuel intake-spraying or intake-heating-spraying means and air heating means wherein liquid fuel is heated to a temperature below its boiling point under a high pressure, with the heated fuel being introduced into the spray means in a mist form to provide a wide contact surface and the fuel mist being mixed with an elevated temperature air to be perfectly gasified thereby.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 246 words
A fuel gasification-increasing device for use with fuel-combustion apparatus comprising: a hollow, cylindrical main body having upstream and downstream ends, the interior of said main body including intercommunicating fuel-intake, combustion-air supply, heating, fuel-spraying and mixing zones in series, the mixing zone being downstream of the fuel-spraying zone, said fuel-spraying zone being defined in said main body by a liquid-fuel nozzle connected to a fuel-pressurizing means, said nozzle being directed axially in said main body toward to the downstream end thereof and having means for discharging a wide, pressurized-spray of fuel as a mist into said main body toward said downstream end, said combustion-air supply means including means for heating and forcing combustion-air into said main body into said mixing zone so that the pressurized fuel mist is substantially perfectly gasified upon entering pressurized, increased-temperature combustion-air whereby the fuel-air using combustion apparatus receives gasified fuel in an optimum condition, said combustion-air supply means comprising a vertically-extending conduit communicating with said main body, blower means connected to an upper portion of said air conduit, and pre-combustion means in said air conduit intermediately of said blower means and the main body, said fuel-pressurizing means comprising an hydraulic pump connected to said liquid-fuel nozzle, said liquid-fuel nozzle including heating means for heating the fuel pressurized by said liquid pump prior to the fuel being directed into said mixing zone, said liquid-fuel nozzle including a plurality of heat-transferring fins disposed about said nozzle for increasing the heat-conducting area of said nozzle.
Claim 2
Dependent Claim 246 words
A fuel gasification-increasing device for use with fuel-combustion apparatus comprising: a hollow, cylindrical main body having upstream and downstream ends, the interior of said main body including intercommunicating fuel-intake, combustion-air supply, heating, fuel-spraying and mixing zones in series, the mixing zone being downstream of the fuel-spraying zone, said fuel-spraying zone being defined in said main body by a liquid-fuel nozzle connected to a fuel-pressurizing means, said nozzle being directed axially in said main body toward to the downstream end thereof and having means for discharging a wide, pressurized-spray of fuel as a mist into said main body toward said downstream end, said combustion-air supply means including means for heating and forcing combustion-air into said main body into said mixing zone so that the pressurized fuel mist is substantially perfectly gasified upon entering pressurized, increased-temperature combustion-air whereby the fuel-air using combustion apparatus receives gasified fuel in an optimum condition, said combustion-air supply means comprising a vertically-extending conduit communicating with said main body, blower means connected to an upper portion of said air conduit, and pre-combustion means in said air conduit intermediately of said blower means and the main body, said fuel-pressurizing means comprising an hydraulic pump connected to said liquid-fuel nozzle, said liquid-fuel nozzle including heating means for heating the fuel pressurized by said liquid pump prior to the fuel being directed into said mixing zone, said liquid-fuel nozzle including a plurality of heat-transferring fins disposed about said nozzle for increasing the heat-conducting area of said nozzle.
Claim 3
Dependent Claim 34 words
The device as claimed in claim 1 in which said pre-combustion means comprises a chamber connected to a separate source of fuel, and ignition means operatively connected to said chamber intermediately of said air-conduit.
