The amount of coal I used over a 24 hr period was 144 lbs, The unit is set for 18lbs per hour of run time, that computes to it must have run 8hrs over the coarse of a 24 hr period. I have no timer on it yet, it is just on and off to maintain set high temp.Protrucker wrote:PatT15 wrote:The feed is not adjustable and is set at 18lbs per hr and the air is set good with almost no unburned coal in the ash. The draft is good with a baro and while the stack temp is hot I have not checked the actual temp. The boiler is in my basement and is well insulated with a metal jacket covering it. It is burning well with no over fire pressure.I'm confused by your statements.PatT15 wrote:At 18lbs per hr this thing is running 8 hrs a day. I'm going to try some different thermostat wiring and see if that helps. I want it to be more like cold start rather than maintaining high limit temp. I know I have heard of a timer that lets the unit run for a min or two every 30min so the fire does not go out. Can someone tell me what that is and maybe a part number.
You say that the feed rate is set at 18 lbs per hr & is not adjustable......
Running 24 hrs a day, that would use 432 lbs a day.
You also say that it is running 8 hrs a day, but you're interested in adding a timer.
It sounds to me like you already have some sort of a timer?
I'm not real experienced with the controls, so let me ask a few questions.....
Is that feed rate of 18 lbs per hr only the feed rate when the thermostat is calling for heat?
Is your statement of, "running 8 hrs a day" just your guestimate of run time or is it an actual set run time?
I hope that I don't appear to ignorant about this!
I want to make it operate so that it runs only, when one of the 5 thermostats calls for heat, but I'm concerned I will need a timer to keep the fire burning. However I may not need it cause I have seen it go 8hrs without coming on and fire still be glowing, in warmer climates.
The house is warm and doesn't need any heat, yet every 20 minutes that thing is down there running for 20 minutes it seems. It runs to much, thats what I want to try and correct.
