Abstract
An injector for co-feeding liquid and solid fuels into a gasifier is provided. The injector includes a body, a first member, and a second member. The body comprises a first channel for conveying a liquid fuel. The first member surrounds the body to define a second channel for pneumatically conveying a solid fuel. The second member surrounds the first member to define a third channel for conveying a fluid stream for dispersing the solid fuel. The liquid fuel is atomized before being mixed with the solid fuel. A method for co-feeding liquid and solid fuels is also presented.
Claims27
An injector, comprising:
- a body comprising a first channel for conveying a liquid fuel;
- a first member surrounding the body to define a second channel for pneumatically conveying a solid fuel;
- and
- a second member surrounding the first member to define a third channel for conveying a fluid stream for dispersing the solid fuel,
- wherein the liquid fuel is atomized before being mixed with the solid fuel.
An injector, comprising:
- a body comprising a first channel for conveying a recycled fines slurry;
- a first member substantially concentric with the body to define a second channel for pneumatically conveying a solid fuel;
- and
- a second member substantially concentric with the first member to define a third channel for conveying a fluid stream,
- wherein the recycled fines slurry is atomized before being mixed with the solid fuel.
A feeding method, comprising:
- conveying a liquid fuel through a first channel;
- conveying a solid fuel through a second channel surrounding the first channel;
- conveying a fluid stream though a third channel surrounding the second channel;
- and
- atomizing the liquid fuel into an atomized liquid fuel before being mixed with the solid fuel.
