Controlling the oil boiler ignition thru the Rk-2001 may be the highest wall I've hit in my first year of burning my biomass 40. Notice that I used I and My in the first sentence.That is because my wife has made it clear that there is no WE in this venture. I reprinted and read several copies of the controller operation manual, installed the wire from Honeywell R7184 oil primary to the Ar 0 ports on the Rk-2001unit. thermostat call for heat and oil boiler keep running with good fire in Biomass 40. Snipped the wire on jumper TT, now oil boiler will not fire at all.
Zennon tells me that I need a relay. I can' fint that page in the manual.
Oil boiler and zone valves are controlled by Honeywell L7224 electronic aquastat. Wood hot water is feeding into return to oil boiler just befor the circulator pump.
Does anyone have a wiring diagrahm for Dummies that will fire oil only when gassifier is not up to a usable temp. Alos need to know where and what kind of relay needs installed.
Read discussions about oxygen sensors used on the lambda boilers but never occurred to me to install one to optimize the inlet ports. Looking forward to seeing his solution for a display off the sensor and what sensor he uses. Keep us informed. I'd love to add to my boiler.
Man you have me jazzed about hot rodding my boiler. So what I think you're saying is you bought the MTX-L from some motorsports supplier and the Bosch sensor from, I guess, an automotive supply house. It looks like that automotive Innovate display does everything, including some neat outputs to a computer if you want. All you do is give the Innovate 12VDC power or something and you have a complete oxygen sensor system for fine tuning the boiler. This looks like a pretty simple add-on. This is very cool Trex! Tell your dad thanks for the research. Yes, keep us informed. I'm thinking this will be very useful for tuning air settings. BTW, 2800 liters is about 740 gals. For us down here that's an odd size and a little under the usual 1000 gal storage used with a 60 boiler. Is 2800l a standard propane tank size in Canada? Why 2800l or 740 gal?
I installed a biomass 60 on 12/04/12. I have nothing but trouble with it. I have spent probably 60 hours messing with it. First I was burning old wood for my wood stove. It was dry but split big. I was getting "FUEL" outs as you can expect. I split the wood down to 4-5 inch size with the same results. Then I had some 4 foot sticks that had been cut for two years, mostly small tops, about 4 inch diameter that I cut to 2 foot sticks and I get the same thing. I dont know what to do. I am getting a lot of smoke out of the chimney and not the steam that everyone talks about. I get a blueish whiteish flame when I have a good bed of coals but there is still smoke. My primaries are about 3/4 of the way open and my secondary is about 1/3. I will post pics later. Lately while gassing, the secondary port hole has been rattling. Im not sure what that means. Any advice? By the way, thank you to all who have posted on this topic. it has got me going in the right direction.....I think.
Also, has anyone tried suppletmenting with coal to extend burn times? In the manual it says "50% soft coal", what does that mean? I appreciate all replies.
Smoke is from unseasoned wood.....Well lets call in not enough seasoning for a gasser...lol
Tell us a little more info
fan shutter % open
Type of wood your burning
Also only 60 hrs messing with it? man you need to spend more time with it treat it like a new born child...LOL
Dont worry the guys here can get you burning like a pro in no time.
How old is the"old wood" for the stove and how long has it been split and stacked under cover?
2 year old rounds may not be dry enough. Wood that is completely encapsulated by the bark dries very slow. I usually try to split even the smaller rounds before I stack it. If a round is too small, I just zip the chainsaw down the length of the piece and it will dry twice as fast as long as you penetrated the bark and the sapwood is visible.
1/3 open on the secondary is too much. On the biomass the secondary inlet is a round hole with a piece of metal you can slide over it to close it down. A little adjustment makes a big difference.
Once you get a good fire going with a bed of coals you can adjust the secondary. Turn down the secondary air adjustment until the flame goes out. Then open it up and getting it going again, the continue opening until the secondary flame goes out again. Then leave it set in the middle of the two extremes.
I've had mine at ~15% all year with good results. 1/3 and the secondary gassification is very poor and intermittent.
OH MAN Larry! here we go we should race our boilers when we get done installing our lamda sensors. LOL
Trex, Did your dad stick with the components and part numbers you posted back in Jan 9 for the O2 sensor? I intend to add that sensor this summer when I do my system upgrades. Have one 500 gal propane tank and looking for the other for my storage add-on. Hope to be posting pics in several months of the new system.
BTW to all BioMass users. Just finishing my 4th season and I don't know if how/what I burn makes a difference regarding nozzle erosion, but my consumption has gone up dramatically with my worn out nozzle. I'll measure the opening and post, but I'd guess the nozzle opening on the primary side has doubled in size basically creating a funnel. The consequence is lots of coals approaching golf ball size in the lower. Easy to image the consequence of rapidly losing coals of that size. Just a heads up that by the 4th season having a spare nozzle on hand might be a good idea. I received mine several months ago from New Horizons and after an hour attempting replacement decided to just wait for end of season shut down to tackle. I'm tempted to cut an expendable metal nozzle entrance from ~1/4" steel to protect the nozzle's ceramic opening. Not sure if that's a good idea or not but have plenty of scrap plate on hand to try. Mainly posting giving a heads up on nozzle erosion so you guys don't get creamed on efficiency mid-season like I did. Ending another season. The best season yet and looking forward to the experiencing storage next season, but thankful at the moment to finally experience Spring and my other passions that need nice weather.
Any other BioMass lessons learned from this season I'd love to hear. AND glad to be still able to pick Mike's brain about his BioMass since he's not going V-gun.
