Ready Set Go Back to the Future

Hello everyone Im a 55 year old steamfitter who is ready to begin the refurbishment of a 520 that is 3 years younger then me. I found it in a Pa coal town home converted to apartments and was just pushed to the side after the oil boiler was hooked up. As I was removing it I said you should be piping this back up but my advice did not go anywhere. the unit is in good shape . It has some metal erosion around the domestic hot water tube bundles . It held under pressure test for days with a new gasket but I will reinforce with weld ment and regrind smooth. ONe mystery is that the ash quide plat was completly cut out and there are just remnants left along the side wall, Why was this done? anyone know.? repair or to allow more ashes to build up before removal required? I plan to reinstall a new ash quide,but would there be any negative effects of not doing so? The door is the old round doors and the data code plate states Gibbons was the boiler manufacturer. 181223a 1956 nsb 33767
I would also like to design a 5 ton rice coal bin but I need to know the slope chacteristic of rice coal flow as I will have a long run from where the truck could get to the bin but I do have a lot of slope available. It on the side of mountain we live on. I thank everyone for this wonderful forum and hope to keep everyone updated as to the progress. We use coal in just a stove now but the 520 will enable me to heat both buildings on site. ARe the round door handles and ash bin handles identicle or unique to each appication ? The baffles are warped should I reinstall or get new ones. Iam not sure exactly where they go but I will read the literature for guidance. I am naming this project "back to the future"

Your best bet would be to send a private message to scrapper_23jr

He sould have access to any repair parts you might need.

Piled coal naturaully makes a 30 degree angle by gravity. If the coal bin has a sloped floor it should be 45 degrees. Less just won't quite do it.
I did a bunch of testing because I'm about to build an indoor bin. I could go on a long time about strel floor, vrs, plastic, vrs wood, but the bottom line is make it from wood with 45 degree slopes.....or no slope at all, the coal will form it's own downward funnel, you'll just have a ton of coal that never gets used.

what slope will rice coal flow down a metal chute that is critical info need and I thank you for your response
