专利汇可以提供Anti-pollution after burner专利检索，专利查询，专利分析的服务。并且This disclosure is directed to an anti-pollution after burner and method for transforming the carbon particles and/or carbon monoxide found in exhaust gases discharging to atmosphere to carbon dioxide. This is attained by providing an after burner adjacent an exhaust stack and utilizing a liquid fuel which has been transformed into a substantially gaseous state mixed with excess combustion air prior to ignition. The hot products of combustion thus generated by the after burner are co-mingled with the exhaust products flowing through the stack whereby the heat and excess air of the generated hot gases effect the combustion of the carbon particles and/or the transformation of the carbon monoxide constituent to carbon dioxide.，下面是Anti-pollution after burner专利的具体信息内容。
2. A method of eliminating combustible emissions and/or the carbon monoxide constituents from exhaust gases discharging to atmosphere, comprising the steps of directing the exhaust gases to a combustion chamber, generating hot products of combustion by effecting the substantial gasification of a liquid fuel, said gasification of the liquid fuel being effected by circulating a portion of the hot products of combustion and mixing said circulated portion with said fuel prior to ignition, mixing an excess amount of combustion air with said gasified fuel to form a homogeneous fuel mixture prior to combustion and mixing said hot products of combustion with said exhaust gases and entrained combustible emissions in the combustion chamber whereby said hot products of combustion with excess air effect the transformation of carbon and/or carbon monoxide constituents to carbon dioxide.
3. An antipollution after burner capable of reducing unwanted emissions from an internal combustion engine, such as a diesel engine and capable of utilizing a low-grade liquid fuel, such as diesel fuel, to operate the after burner, said after burner including a combustion chamber to receive the emissions from said engine, said chamber having an inlet to receive said emissions and an outlet, a generator to generate hot combustion gases, said generator including a gasifying chamber, means to supply liquid fuel to said gasifying chamber, a burning chamber, an air inlet to said burning chamber, and means to return a portion of the products of the combustion occurring in said burning chamber to said gasifying chamber to supply gasifying heat for use to gasify liquid fuel entering said gasifying chamber and means to direct the hot gases together with excess air to said combustion chamber whereby said engine emissions will be subject to further combustion to reduce the unwanted pollutants.
4. The invention as defined in claim 1 and including means disposed in said combustion chamber to effect the intimate mixing of said exhaust products of combustion with said generated hot gases and excess air.
5. In combination with an exhaust of internal combustion engine, a combustion chamber having means defining an inlet and an outlet thereto, means for connecting said exhaust of said engine in communication with said inlet whereby the exhaust products of said engine and any combustible emission entrained therein are directed to said combustion chamber, burner means operatively associated with said combustion chamber, means for introducing liquid fuel and an excess of air to said burner and burning said fuel therein so that the resulting products of combustion define a mixture of hot combustion gases with an excess of air, means for recirculating a portion of said products of combustion back to the inlet of said burner, and means for directing said hot mixture of combustion gases and excess air to said combustion chamber to co-mingle with said exhaust products to change any carbon particles or carbon monoxide in said exhaust products to carbon dioxide.
6. An antipollution after burner comprising: a combustion chamber having an inlet and an outlet, said inlet being adapted to connect in communication with a stack through which exhaust products of combustion and any unburned carbon emission are exhausted, a burner means operatively connected to said combustion chamber, said burner means including burner head, a burner nozzle connected to said burner head, means in said burner head defining a mixing chamber, said burner head having an orifice communicating said mixing chamber with said nozzle, a fuel gasification chamber connected in communication with said mixing chamber, means for introducing liquid fuel into said gasification chamber, means for heating said liquid fuel within said gasification chamber to effect substantial gasification of said liquid fuel, means for introducing excess combustion air into said mixing chamber to form a homogeneous fuel mixture with said gasified liquid fuel, means for effecting ignition of said homogeneous fuel mixture, and means connecting said nozzle to said combustion chamber for directing the hot products of combustion from said burner nozzle to said combustion chamber whereby the hot products of combustion co-mingle with said exhaust gases to transform any carbon or carbon monoxide in said exhaust gases to carbon dioxide.
7. The invention as defined in claim 6 wherein the means for effecting gasification of said liquid fuel includes means connecting said nozzle to said gasification chamber for recirculating a portion of thE products of combustion to said gasification chamber.
8. The invention as defined in claim 7 wherein said means connecting the nozzle to said combustion chamber introduces the hot products of combustion tangentially of said combustion chamber.
9. The invention as defined in claim 8 and including a baffle means disposed in said combustion chamber, said baffle means being disposed over and spaced from the exhaust inlet thereto for directing the exhaust gases entering therein toward the periphery of said combustion chamber so as to enhance the co-mingling of the exhaust gases with the products of combustion of said burner.
10. In combination, an internal combustion engine having an exhaust stack, a combustion chamber having an inlet and an outlet, said exhaust stack being connected in communication with said inlet, a baffle means disposed in said combustion chamber in spaced relationship to said inlet, said baffle means being spaced from the walls of said chamber for directing the exhaust products flowing through said stack toward the walls of said chamber, a burner means operatively connected to said chamber, said burner means including a burner head having a face portion, means defining a burner orifice formed in said face portion, a flame nozzle connected to the face of said burner head, means defining a mixing chamber formed in said burner head, an air injector nozzle extending into said mixing chamber, means defining a gasification chamber disposed in communication with said mixing chamber, means interconnecting said burner nozzle in communication with said gasification chamber for effecting the recirculation or a portion of the hot products of combustion generated in said flame nozzle to said gasification chamber, whereby the heat of said recirculating products of combustion is utilized to effect gasification of said fuel, means for directing combustion air to said air injector to mix with said gasified fuel to form a homogeneous fuel mixture, means for effecting ignition of said homogeneous fuel mixture, and means interconnecting said flame nozzle to said combustion chamber to effect a co-mingling of said hot products of combustion with said exhaust products in said combustion chamber to transform any carbon or carbon monoxide to carbon dioxide.
11. The invention as defined in claim 10 wherein said last mentioned means introduces said hot products of combustion tangentially of said combustion chamber.
