Well I finally got started on the fabrication of my boiler!

You can check out some of the pictures here: https://www.dropbox.com/sh/h4lbsxbz8g5ckco/snOXOEeL1E

Alright, glad to see a current build thread!

Looking good, nice pics.  I would be interested in a better angle of how you laid the firebrick in the secondary.  It looks like your nozzle is in the middle of the burn chamber?  Does the firebrick route the gases forward first- or is it just open to go back towards the heat exchangers?  I'd also like to know what firebrick you used,  I'm trying to lay my secondary out in CAD with the brick, to minimize cutting.

Nice build!! Looks awesome and looks like you have the equipment to do it too!
Brings back memories of my build but mine didn't turn out that nice.

Actually, I will be using refractory cement instead of firebricks.  I have not put the cement in the boiler yet though.  That will be done once I get the water jacket on and tested for leaks.  I may lay some firebricks under the nozzle so that they can be easily replaced.

I have heard that the refractory cement is really hard to work with and expensive. Do you have any experience with it or just going to give it a go? Personally I always like to give anything a go and see what I can make happen.

I added a few more pictures to the Dropbox of our build.  We decided at the last minute before we put the top on to add a pipe for possible future burning of wood chips.  We installed a flapper on the bottom of the pipe that will be counterbalanced closed and will also build and install a rotary valve on the top side of the pipe to meter in chips fed from an auger.  That part will take some more designing at a later date.  We thought we should do it now to make it easier down the road.

I see you have 3 air channels into firebox, whats the purpose of the top inlet?  Most I've seen use air midway or even lower, and air at the nozzle.  I guess its better to have it and not need it than need it and not have it?

I finally got this boiler installed and have it heating my house and a 45x60 shop with floor heat.  It works great!

I am also measuring the temperatures with a Click PLC and some ESP8266 flashed with Tasmota.  I have the readings going to my Home Assistant instance and logging the data with InfluxDB and Grafana.
