Burning coal from Cornwall Supply in Cornwall,NY. Coal -trol max at 40 & Min at 6. Burning 1 to 2 inch thick line on grate at approx. 2-1/2 inches from end of grate.
Coal-Trol regulates to +/- 1 degree. Burned about 100 lbs in two days of 18-25 degree weather to heat 2000 sq ft.
Is it normal for fire blower fan to run at a constant speed or should it vary?
Can an adjustment of my Max setting somehow make the coal burn completely?
Any explanations for the unburned coal and possible fixes are appreciated. I hope it is as simple as adjusting the max setting.
Other than the unburned coal I am very happy with the LL Hearth & Coal-Trol combination.
P.S. Sieve pic blurry but that's a dime for size reference.
I do not have the Coal-trol but a Keystoker Ka-6 boiler. I am burning a load of coal I purchased from Steve at Cornwall Coal. He supplies a dealer north of hear and heard nothing but good things from him so I got 24 tons. When I first started burning last month I had a lot of unburned coal and I mean a lot. Many told me the coal is bad. Then I realized I did not have the small combustion blower intake open. Once I opened it the coal burned great. I have both blowers wide open now and there is very little unburned. This coal is very hard and shiny and needs lots of air. Some have said it may be from Jeddo's but I really don't know. If there is a way to increase your air I would do it. I believe you will see a huge difference.
I have been burning 60-70 pounds a day since it got colder last week in a 2000 sq foot house built in 1838. It has been around 12-16 at night and 20-26 during the day and very windy. Thermostat is at 67. I am burning buckwheat and have both air feeds wide open.
Here is a link to a discussion on it.Pictures of ash and quality
