In general, the SCR unit is located between the furnace economizer and the air heater, and the ammonia is injected into the catalyst chamber through an ammonia injection grid. As in other SCR applications, the temperature of operation is critical. Ammonia slip (unreacted ammonia) is also an issue with SCR technology used in power plants.

Selective non-catalytic reduction (SNCR) is a method to lessen nitrogen oxide emissions in conventional power plants that burn biomass, waste and coal.The process involves injecting either ammonia or urea into the firebox of the boiler at a location where the flue gas is between 1,400 and 2,000 °F (760 and 1,090 °C) to react with the nitrogen oxides formed in the combustion process.
Then knit the stitches that were slipped and slip (again wyif) the stitches that were knitted. In the end, one should obtain a "pocket" that can be opened (be sure to use wyif slip-stitches during binding off as well!) The wyif slip stitch prevents the yarn from crossing over to the back fabric, so that only the front fabric is knitted in any row.

Herringbone stitch [6] Linen stitch is a pattern that creates a tightly knit fabric that resembles woven linen. Tailored garments are especially suited for the linen stitch. It is a durable stitch, and is often used to reinforce the heels of hand-knitted socks. It includes knit and purl stitches, as well as slipped stitches. [7] Loop stitch [8]
To execute it, start by figuring out how much yarn is required for the cast-on row, and pull out that amount of yarn. With that, put a slip knot on the needle (this is not absolutely necessary, since the first cast-on stitch will create a slip knot in the process, but it is generally more secure to start with a slip knot).
