An injection quill design and methods of use for injecting a first fluid into a second fluid. The injection quill may comprise a hollow stem having a closed end and a sidewall, the stem having a curved cross-section defined by a major axis, and a minor axis, and at least one orifice for injecting the first fluid into the second fluid, wherein the major axis is greater than the minor axis and/or the orifice extends through the sidewall and/or the orifice has an internal chamfer with a chamfer angle ranging from less than 0&#xb0; but greater than 90&#xb0;.

Injection quill designs and methods of use

The present application provides a slurry concentration system for concentrating a flow of slurry. The slurry concentration system may include a boiler for producing a flow of steam, a first evaporator for concentrating the flow of slurry with the flow of steam and creating a first flow of water vapor, and a second evaporator positioned downstream of the first evaporator for further concentrating the flow of slurry with the first flow of water vapor and creating a second flow of water vapor.
