I have a royall indoor wood boiler and with the wright situation it back fires enough to blow my clean out door open anyone ever experience this
I had the forerunner to the Royall, the Energy Mate. Mine would backfire too at times. Make sure you have dry wood & good draft. Try to keep the grate from plugging. Thats about all I can suggest, Randyjimmywoody said:I have a royall indoor wood boiler and with the wright situation it back fires enough to blow my clean out door open anyone ever experience this
If you think the poofing on wood is bad try soft coal, I almost blew the stovepipe off mine. Lucky I had a barometric on it to blast out the side. Do you get extremely high flue gas temps with yours? I talked to the engineer & he said 1400 degrees external was normal & that meant 2800 degrees internal in the flue pipe. He said glowing a dull red was normal, Randycheapsx said:I have an energy mate and do experience the big POOF at times. I let the wood all catch and get going good before closing it up. If you can load when the fan wants to run that helps after closing it up to prevent the POOF. Mine is a draft issue because it's in the cellar with an outside ss chimney. There is a huge volume in these things for smoke to build then ignite or explode when enough air gets to it.
Yes, that is getting towards open hearth temps. The chimney really only saw the 1400 degrees though as the center stream was the part with the high temps, as they explained it to me, Randyjebatty said:With those numbers, this is a smelter, not a boiler. Very dangerous. Class A is only rated for somewhat over 2000F short term emergency chimney fire protection.
Just to clarify Jim, The engineer that I talked to in Franksville Wis at the factory said it was not unusual for the ones they were making to run 1400 degrees on the pipe out side & that the internal stream was around 2800 degrees. He said the pipe would glow at those temps & this wouldn't hurt anything. I didn't feel he was lying because he would have no reason to. The steel only saw the 1400 degrees. He also said this was necessary to "burn up the creosote". My Energy Mate didn't run those temps, that said the flue gas temps were off the chart for my gauge. My boiler was rated for 150,000 output, the owners manual stated that it was 50 percent efficient. So wood was being consumed at 300,000 btuh with this small boiler, fired hard I believe it was beyond this, approaching Garn territory from a small boiler. The ones made in Franksville had a grate area twice what mine was & straight sided chamber, they did that so it would burn anthracite & they put in standard shaker grates at that time. I know it seems preposterous that someone would make a "blast furnace" like this...... Randyjebatty said:Mild steel reaches a dull read at 1200F, and at 1400F is quite bright red. As to 2800F interior, mild steel melts at 2690F, and stainless steel melts at 2550F. Blacksmith It's hard to imagine any metal surfaces being in contact with 2800F temperatures.
