Burning apparatus and method

专利汇可以提供Burning apparatus and method专利检索，专利查询，专利分析的服务。并且The burning apparatus and method are specially suited for burning comminuted solids contained in a liquid slurry, and are particularly useful in the burning of floatable wastes known as ''''skimmings.'''' The skimmings are removed from the surface of a liquid in a skimming tank for sewage or other wastes. The skimmings are then sent through a grinder to grind up the solid floatable wastes, and mixed with water, if necessary. The resulting slurry is pumped to a holding and settling tank, where the water and floatables are allowed to separate from one another. The water is decanted off, and the skimmings are heated and delivered to a rotary-cup type burner with enlarged liquid flow passages. Steam is fed into the slurry before it is atomized, and the atomization product is ignited and burned. Supplementary fuel can be added to the slurry-steam mixture, if necessary. Preferably, a combustion chamber is used to help support combustion. After the chamber has been heated, the slurry can be burned without supplementary fuel.，下面是Burning apparatus and method专利的具体信息内容。

权利要求

1. Apparatus for burning comminuted solids in a liquid slurry, said apparatus comprising means for introducing said slurry into an atomizing fuel burner with liquid flow passageways relatively larger than the size of the solid particles in said slurry, means for introducing steam into said passageways, and means for igniting the atomization product, said atomizing fuel burner including means for spinning a portion of the conduit containing the mixture of steam and slurry at a relatively high speed to form a thin fluid film on the inside of said conduit portion, and forming an air jet to mix with the mixture flowing out of said portion.

2. Apparatus as in claim 1 including a combustion chamber receiving the atomization product, and means for pre-heating said chamber.

3. Apparatus as in claim 1 including means for pre-heating said slurry, and in which said introducing means is a steam conduit.

4. Apparatus as in claim 1 for introducing a fluid fuel into said slurry.

5. A skimmings disposal system including means for comminuting solids in said skimmings, a settling container for separating water from said skimmings, means for heating said skimmings, a rotary cup atomizing burner with enlarged fluid flow passages, means for introducing steam into said skimmings, means for introducing a fluid fuel into said skimmings, and means for delivering the mixture of steam and skimmings, together with any fluid fuel used, into said burner.

6. A system as in claim 5 including a combustion chamber in which the burner output is burned.

7. A method of burning comminuted solids mixed with a liquid in a slurry, said method comprising the steps of atomizing said slurry, mixing steam with said slurry prior to atomization, and igniting the atomization product, said atomizing step consisting of spinning said mixture at a relatively high speed to form a thin liquid film on the inside of a fluid flow conduit and forming an air jet to mix with the mixture flowing out of said atomizer.

8. A method as in claim 7 including the steps of heating said slurry to a temperature of from 180* F. to 200* F. prior to atomization.

9. A method as in claim 7 including the step of discharging the atomization product into a combustion chamber, and pre-heating said chamber to a temperature of at least 1,000* F. prior to forcing said slurry through said atomizer.

10. A method of disposing of waste skimmings including solids, said method comprising the steps of grinding a mixture of said skimmings and water so as to comminute said solids, holding the resulting mixture in a container, separating a substantial portion of the water from said skimmings, mixing steam with said skimmings, atomizing the resulting mixture, and igniting the atomized mixture, said atomizing step consisting of spinning said mixture at a relatively high speed to form a thin liquid film on the inside of a fluid flow conduit and forming an air jet to mix with the mixture flowing out of said atomizer.

11. A method as in claim 10 including the step of adding a fluid fuel to said skimmings.

12. A method as in claim 10 including heating said skimmings to a temperature of approximately 180* F. to 200* F.

13. A method as in claim 10 including discharging the atomization product into a combustion chamber, heating said chamber to a temperature of at least 1,000* F. with the use of a fLuid fuel in said atomizer, and continuing combustion without said fuel.

14. A method of disposing of waste skimmings including solids, said method comprising the steps of grinding a mixture of said skimmings and water so as to comminute said solids, holding the resulting mixture in a container, separating a substantial portion of the water from said skimmings, mixing steam with said skimmings at a rate of approximately one-half to one and one-half pounds of steam per gallon of skimmings, at from 5 to 15 P.S.I.G., atomizing the resulting mixture, and igniting the atomized mixture.

15. A method of disposing of waste skimmings including solids, said method comprising the steps of grinding a mixture of said skimmings and water so as to comminute said solids, holding the resulting mixture in a container, separating a substantial portion of the water from said skimmings, decanting said water from said container, heating said skimmings in said container to approximately 180* F. to 200* F., mixing steam with said skimmings, atomizing the resulting mixture, and igniting the atomized mixture.
