Kalamazoo problems

PostBy: BigDog1947 On: Mon Oct 06, 2008 4:25 pm

Hello all, I would like help with maintaining a good all night burn in my hot air furnace. Currently I am unable to maintain a all night burn, it goes out before the coal is burnt up. All draft is from under the coal grates and I have a 25 plus chimney that burnes wood perfectly. What could I be doing wrong? The fire box is 3 feet deep by 2 feet wide and all of a foot from grates to the top of the brick. The grates are shaker grates as the main function of the furnace is to burn coal. I have achived a fair burn with leaving the ash pan door partly open, I know I cant do that as common practice. Any help would be great.

Before you shake it down and reload it for the night, open the ash door and get the fire revved up. Once it is banging out some heat, shake it down and reload. Dumping fresh coal on a low fire is not a good idea. If it is a V shaped firebox, you may want to bank the fire before reloading.

Do you have a barometric damper?

Hi, coaledsweat. Yes there is a barometric damper. Should I fasten that closed so it won't open to get more draft? There is a tee off the furnace and a length of pipe , an elbow and another length of pipe with the damper and then another elbow into the chimney. Thanks for getting back to me.

Are you filling the firebox with coal fully?

No, my concern was overdraft with out one, that would eat a fire up fast.

HI, Devil505 no I'm not filling the fire box full. I'm new to burning coal. I have had this furnace for 20 years but have always burned wood. The fire box is really big so am afraid of building too big of a fire. thanks

Anthracite coal needs a deep bed to burn. Too little will not burn very long. It;'s not like wood in that you control the heat output by controlling the air, not by the amount of fuel you put in.

Hi there bigdog1947. Devil505 brings up a very good point in that coal needs a deep bed to burn well or at all and that the heat is controled by air flow not the amount of fuel. It is hard for folks that have burned wood for a long time to grasp the fundamentals of burning coal as they contradict each other at certian points.

Thanks, Devil505. My furnace has a thermostat up stairs that controls the draft door. It is either open or closed. It has a chain going down to the draft door that could be adjusted to the amount of open or closed. I'm wondering if that should be left alone. thanks.

Bigdog, your air inlet damper on that model of furnace is what I like to call all or nothing. It would be very hard to near impossable to maintain a steady rate of burn in your hot air furnace with that type of air inlet. The thermostat tells the damper door to open all or close all, it does not adjust thats why I say its all or nothing. You can adjust the length of the chain or the throw on the arm/cam atached to the motor to allow the air inlet to be allmost closed to all open. Allmost closed will allow the coal fire to run in a throttled back state and be ready for when the thermostat says all open. 20 years ago I used a similar setup with good suscess burning coal. I see that you live in the finger lakes region aswell. I bet the fishing is great.

Bigdog just so you know, Homestead coal will be selling bulk for $218 a ton untill the 300 plus ton is gone then they will adjust the price to there new purchase price. You would be nuts not to go nuts on the nut coal. :D :D :D
