I have a EFM model DF520 stoker boiler and would like to replace the coal pipe bin feed end that goes over the auger. Can anybody tell me;
1. The width (it looks like it's either 2 or 2 1/4 inch)
2, Length of pipe I need
3. Is the pipe a standard type? Can I go to my local plumbing store to buy it?
4. What is the substance I place between the pipe and the coupling?
Thanks for your help.

On a 520 the bin and feed pipes are standard 2" schedule 40 pipe. The bin pipe is usually galvanized steel , but some people have used PVC because it's cheap and easy to cut. The PVC will work but it won't last as long as steel.
The length of the bin pipe is directly related to the length of your bin auger. You need to measure it. You want the bin pipe just long enough so that there are 1.5 to 2 auger flights sticking out the end.
I'm not aware of any "substance" between the coupler and the pipe. I would put a bead of caulk around each end of the pipe coulper though to keep the coal dust from leaking out.
