Automatically feeding your boiler is an appealing option for a lot of people. Typically, as a boiler manufacturer, we like to stay out of providing feed systems (which typically require custom desigin) and supporting them out in the field. Instead, it works better for us (and you) if you look into buying directly from a local farm supplier. This way, you avoid the expense of a middle man (we just buy from our local farm supplier) and you get local support if you ever have any maitenance issues.
That said, you're probably wondering what to ask for when you do talk to that local farm supplier. We recommend a 6" tube standard grain auger with screw type flighting. Don't go with the open core flighting as it allows the coal to fall back down the middle of the auger. Also, depending on how large your coal bin is, you may want to get another larger piece of tubing to run the auger through so that the weight of the coal doesn't crush the auger. In our setup here, we are using an old farm silo as a coal bin (it holds upwards of 50 tons), so we definately needed something to keep the full weight of the coal off of the auger iself.
To control your auger, you have two options. You could activate it by hand as needed, saving yourself the work of shoveling the coal up to the hopper or you could use some sort of a sensor to automatically activate the auger when the hopper gets low. If you choose the second route, you are looking for something typically labeled as a "hopper level control". It should be available from any feed handling company (hopefully from that same local farm supplier).
With an autofeed system, you might also want to consider a way of controlling the coal dust that will come from the coal falling out of the auger. On our machines, we sell a special hopper cover that has a hole in the top to attach your auger and a hinge in the middle to still allow you access to the hopper.
If the do-it-yourself route is not for you and you'd prefer the convenience of a ready-made system, we do provide custom automatic feed systems containing all the components I just mentioned.
Automated ash handling is a bit more novel of an idea than automated fuel loading. We do have some customers who use an auger in a manner similar to above to carry the ash away from their boiler. You would need some sort of funnel to channel the ash from the boiler into the auger. Once again, you can hand activate the auger on an as-needed basis or use some sort of electronic sensor to activate it automatically. One soultion to ash removal that is both simple and elegant (in our opinion) is to raise your boiler up on blocks or on a concrete platform to allow you to get a skid-loader bucket underneath the boiler to scoop out the ash. This is the method that we use here to remove ash in our setup. It works particularly well in a new construction where you can "sculpt" a concrete base for the boiler and build a small access door for the skid-loader, giving you a very professional looking setup.
