I'm firing my gas kiln with one burner , input and chimney output shown in blue. It's not an option to add another burner at this stage.

I've always had a problem that the back lower and middle section is reduced more than elsewhere. Even with damper adjusted to wider and lower settings, I can't get properly oxidised bisque there, and glaze is a little over reduced compared to rest of kiln.

I recently added the bricks in green to deflect some flame into the front section more, I'm happy with how those helped. The back section here is how I've had it set for ages, it gives too much reduction at back bottom and middle.

Last firing I added the bricks in red. The middle section improved slightly I think, but the bottom back got super reduced, the tankards in red I probably won't even attempt to glaze. So this seems like I've made things worse overall at the back.

I'm wondering now if I should just removed everything at the back in yellow? Just make more space there, have a tiny one brick deflector on the back wall, and keep the green bricks at front. Any thoughts? Thanks
