Claims
- 1. A method of controlling combustion in an amendment or compost mass, comprising:
- injecting a fire control fluid flow into the compost or amendment mass through at least one lance;
- providing said lance with an outer fire control fluid flow wall spaced from an inner air control insert; and
- providing a plurality of openings in said inner air control insert and means for separating portions of said insert and said outer wall to form separate fluid flow zones to provide a fire control fluid flow profile along the length of said lances into said compost or amendment mass.
- 2. The method as defined in claim 1 including adjusting said separating means to change said fire control fluid flow profile.
- 3. The method as defined in claim 1 including varying the spacing of said control insert openings along the length of said lance.
- 4. The method as defined in claim 1 including providing a plurality of said lances and injecting the fire control fluid flow through said plurality of lances.
- 5. The method as defined in claim 1 including providing valve means for controlling the fire control fluid flow through said plurality of openings.
- 6. An apparatus for controlling combustion in an amendment or compost mass, comprising:
- at least one lance means for providing a fire control fluid flow profile in the compost or amendment mass, said lance means including an outer porous wall and means for forming at least two inner fluid flow control zones to form said fire control fluid flow profile; and
- said means for forming said zones include a single inner fluid control insert having a plurality of openings along the length thereof spaced from said outer porous wall with at least one laterally adjustable gasket sealingly engaged on said insert between said insert and said wall to form said zones.
- 7. The apparatus as defined in claim 6 wherein said insert openings have at least two different spacings along the length of said insert.
- 8. The apparatus as defined in claim 7 including a plurality of gaskets adjustably mounted on said insert to form a plurality of variable zones.
- 9. The apparatus as defined in claim 6 including internal valve means for adjusting the fire control fluid flow through said insert openings.
- 10. The apparatus as defined in claim 9 wherein said outer wall is formed from a mesh tube, said control insert is formed from a stainless steel tube spaced from said wall by said gaskets and said valve means is formed from a stainless steel tube formed to fit inside said control insert.
- 11. In an apparatus for controlling combustion in an amendment or compost mass, including means adapted to inject a fire control fluid flow into the compost or amendment mass, said injection means including a plurality of lances having at least one fluid flow passageway in each lance, manifold means coupled to the fluid flow passageways in said lances for directing fluid flow towards said lances, the improvement comprising:
- at least one lance means for providing a fire control fluid flow profile in the compost or amendment mass, said lance means including an outer porous wall and means for forming at least two inner fluid flow control zones to form said fire control fluid flow profile; and
- said means for forming said zones include a single inner fluid control insert having a plurality of openings along the length thereof spaced from said outer porous wall with at least one laterally adjustable gasket sealingly engaged on said insert between said insert and said wall to form said zones.
- 12. The apparatus as defined in claim 11 including internal valve means for adjusting the fire control fluid flow through said insert openings.
- 13. The apparatus as defined in claim 12 wherein said outer wall is formed from a mesh tube, said control insert is formed from a stainless steel tube spaced from said wall by said gaskets and said valve means is formed from a stainless steel tube formed to fit inside said control insert.
- 14. The apparatus as defined in claim 11 wherein said insert openings have at least two different spacings along the length of said insert.
- 15. The apparatus as defined in claim 14 including a plurality of gaskets adjustably mounted on said insert to form a plurality of variable zones.
