Hi all,

I hope shortly to be receiving a DJB conversion kit for Edrig. While I have watched some coal firing and read a few articles, I know even less about this than I do most things. Two things presently concern me:

(a) where to get good coal -- I know that most coal is not suitable, but do not know what is presently available. Coles has not (yet) responded to an e-mail. (I have some lovely decorative coal courtesy of a kindly NY magazine publisher, but it is apparently composed of asbestos, won't light with a blow torch.)

(b) source for accessories, esp. blower fan.

And yes, past practice suggests that I won't need these for years, but I might actually fool mysself and get it running, so, any info gratefully accepted.

Best regards, Mike

I thought that the DJB projects have accessories...otherwise get an Accucraft or Aster fan, find a good spoon and modify it for a shovel, gun supplies for flue brushes, and some hard charcoal should get you started

Call Coles and place the order for the coal. Having Welsh will certainly help your success with firing.

the Southern Steam Trains site has a great article online regarding coal firing.
you'll find an Aster blower fan there, too.


agree with their recommendation of Welsh coal, but also agree it's not easy to find.

the Riverside Live Steamers (all steam ops) 90 minutes up the road from me is where i'd start.


good luck.
cheers...gary

GOOD COAL IS THE SECRET to success. First time I fired the Coal Ruby I didn't have Welsh coal. I used some I got from Chama. It put out the stinkeyest, yellow gunk you have ever seen. After three runs I couldn't get steam up any more (NOT ME THE LOCO). The smoke stack was stopped up from all of the unburn't volatiles, so I reamed it out with a drill bit and every thing was good again when the 6 gallons of Welsh coal arrived. (Complimets of Bob McHale) Thanks again Bob.
I also would suggest an axle pump which is almost a requirement for coal firing.

this a video we did a while back of Bill Courtwright firing his SRRL 24. He has great sucess using Charcoal to start and the Welsh coal. Ives uses only hard charcoal.
I found some charcoal here in the Houston area from Braziel that Jeff said worked fine in my Aster C-62. Hopes this helps. As you can see it does take patience.

I recently got 10lbs of welsh coal from Cole's, Just pick up the phone and dial (409) 547-3400. In the last few weeks I've successfully fired an engine that several people had tried and failed. I followed the instructions I found on Jim Pitt's web site. I followed his instructions to a TEE with the exception of lamp oil. I used the standard grade A-1 kerosene that I use to heat my garage in the wintertime. Here's the tips I tell my self while firing up:
  1. Have a GOOD, DEEP charcol fire going and on the steam blower before adding coal.
  2. Add a few scoops of coal, let it catch fire well.
  3. Add a few more scoops and wait again as in step two.
  4. I try to let all the charcol burn out and have a good deep bed of coal (as deep as possible) before pulling out on the track.
  5. DON"T FORGET to monitor the water level while steaming up on the blower.
I'm a rank novice as I have ran this engine only twice and I'm still working out the bugs with the loco (wheel gauge, water leaks from the tender pump, new clack valve fittings, etc), but it produced steam for about 45 minutes each time and I only quit because I wanted to shut it down.

P.S. I'm using an Aster suction fan to get it to 20psi before moving to the steam blower.

P.P.S. I watched John Shawe fire an engine of his own design and manufacture at Diamondhead this year. It was O GAUGE, talk about a small firebox! It ran perfectly. Check out his article on Jim's web site.

The only thing I will add is that the charcoal must be real charcoal, not bricketts. I have found misquet (My spelling isn't good without spell check)works good. At any rate it must be hardwood. I get mine at the local supermarket.

Also, the charcoal must be soaked in somekind of fluid to aid in lighting. I use regular charcoal lighter fluid.

And here are comments on the comments:
USE WELCH COAL!!!!!!!! I have always been able to get mine from Coles.
My Aster draft fan works just fine.
See both the Southern Steam Trains and Roundhouse - Engineering articles on coal firing.
You will need both a shovel and a pick. The pick is used mainly to open and close the firebox door.
Be sure to break up both charcoal and welsh coal to the proper size. This is not real critical but too big does not burn well. I use pruning shears to bust up both types of coal.
The axel pump is a must for really enjoyable coal firing.

When I made my first try at coal firing, I used a stationary test stand. I recommend this way to start.

Just a couple comments from another newbie to coal with a Sabre Steam Annette [Lady Anne conversion].

Stick with Coles for your Welxh coal. You get 20 pounds in a USPS flat rate box, normally the next day. In addition, they are good people to work with.

MOST IMPORTANTLY, REGARDLESS OF COAL TYPE, KEEP YOUR GRATE CLEAR OF ASH! No fan will provide a strong draft if the grate is plugged up with ash.
Good luck!

About twenty-five years ago, we burned Welsh coal in our 1/8 scale Mogul. It was hard to get then. Our source was David Rose (the music composer and member of Los Angeles Live Steamers). He had it shipped to his home in Sherman Oaks, CA in bags inside machinery crates he had purchased in England. It was the primo stuff alright! Now we have to use West Virginia Pocohontas coal. You get lots of clinkers with this coal.

I will cut and paste an email I sent to Britstrains on running her coal fired ruby, I think she had success with this and I hope you also do,


Hey Brittany,

I will explain what I do in a large paragraph, then answer yours questions underneath, but remember, every engine will act different (even the big ones do) and you have to learn your little engines specifics.

Here is what I figured out.

Materials:

1. Coal Fired Engine
2. Blower (aster one works fine, has to be powerful enough to keep the hardwood charcoal fire up)
3. Lamp Oil (paraffin) (people use other things also)
4. Hard wood charcoal, the stuff you find in those fancier supermarkets or home depot(I think) the regular charcoal is pressed sawdust doesn't get hot enough
5. Welsh Coal (Its from poland now I think LOL) http://colespowermodels.com - you have to call him and ask for the USPS flat rate box welsh coal special lol (cheapest in shipping this way)
6. 4 small bins, easly accessible
7. wire fencing with bean size holes in it
8. bucket
9 small sifter (anything that will hole your nice coal on top and let the silt fall through, healthy fires require that the coal be uniformed(ish) and bean size for djb ruby firebox anyway)
10. water sprayer with goodall adapter to advert disaster (incase your water falls too low - unsafe conditions)

(optional)Dirty bituminous coal

Hi all,

I would be amazed at the outpouring of helpful advice, except that I've gotten such responses before. Many, many thanks.

For years, I've explained to non-believers that normal people think that guys who play with trains are strange. Sparkies say, "No, we're all right, but have you seen the live steamers?" Live steamers say "No, the real eccentrics are the guys burning coal." BUT I've wanted to be an eccentric for a really long time.

Thanks, and best regards, Mike

1 more thing about tools, I hope your coal fired kit comes with the shovel. I know the shovel has to be a certain size to your firebox hole, so whoever builds your boiler also needs to supply the shovel in most cases. I use the aster (2 C battery version) and bring my coal fired ruby up, just keep in mine most electrical blowers can not keep a coal fire going but can easily keep the charcoal part of the fire going good. to run on coal you need steam driving draft (in most cases, - yes I know you can put your vacuum cleaner on it... lol)

Just some of my experiences, I too read all the websites and postings on running the coal engine but you have to figure out what methods are best with you and you need to tweak them as you go, every coal engine seems to have a soul and they act a little bit different every time you fire them up. It is what makes it fun! Till this day, most of the time, my ruby wants to run and sometimes it likes to limp around (depends on how much I am paying attention on that particular day), but I know 1 thing for SURE, it LOVES to run on the diamondhead white track circle!!!

On the real wood charcoal vs. briquettes discussion...

I went into a Meijer's store here in suburban Detroit, and asked the young man, "Do you have any real wood charcoal--not briquettes?" He looked at me kind of strangely and asked, "Isn't all charcoal briquettes?"

Wrong generation!

There is a real charcoal around here from time to time, I think the brand is "Royal Oak". I recall a guy using it, I think he soaked it in kerosene to get it started.

One can run on real charcoal. Yves Guillaume only uses "real coal" what he calls "smokey coal" to make a plume and a little smoke smell his main fire is charcoal; however, it is not just plain old charcoal. He has told me where he gets the charcoal and what type it is but I do not remember. It is not a wood I ever heard of before. The engine he takes to Diamondhead was designed by ASTER to run on charcoal.

In theory wood will work but it would take a lot of firing.
 
#22 ·
I remember going to Diamondhead years back and when you walked into the place the alcohol fumes would just about burn your eyes. Now, you walk in and the coal smoke and aroma is thick as a knife. Who would have thought that coal firing would have become as big a part of the hobby as it has become.

Here is an overview of coal firing while using rollers:
Building the initial fire with a bit of hard charcoal


Image


Image

Awaiting for the bed to set with a good charcoal fire as per John Shawe:

All now looks rosy, however the crucial moment is now looming when the paraffin burns away there will be no more flames and it is quite possible the top of the fire will appear black and very unhealthy, most disconcerting for a fireman trained on a meth burner. Confidence is now all important and the trick is to do nothing, shutting the door and allowing the fire to burn through; honest, it hasn't gone out!


Image

Pressure is up, fan off and blower on. again as per John: If your blower is exceptionally feeble (as mine often is due to the antiquity of my batteries) you may have to continue with charcoal until there is enough pressure to use the steam blower. Continue to build up the fire with coal and by the time working pressure is reached all of the charcoal will have burnt away.


Image

Feeding the hungry dragon a spoon of Welsh coal- Once pressure has risen to about 20 psi, the electric blower can be removed and the steam blower turned on. Continue to build up the fire with coal and by the time working pressure is reached all of the charcoal will have burnt away. The fire will consist of the, now red hot coal that you've been busily shoveling in since taking the electric blower off. (J Shawe)


Image

Good estalibshed coal bed, pressure and set to go


Image


Fire box and grates glow and no sign of ash buildup

Image

Open the throttle and let the beast run.....With a good thick bed of hot coal you will find it possible to completely fill the firebox before departure[ for us about the bottom of the door opening], allowing a longer run before more coal is required. (J. Shawe)


Some aspects of failure (yes, have encountered many)
Air flow: ash pan and the flues (especially if you have too big or too small coal that either blocks or get sucked into the flue blocking air flow)
Too much/too little: too much charcoal and too little time getting that deep bed of glowing coal
Size: size does matter (except for the K27 that are very forgiving)
Balance: keeping the pressure up with a good balance of fresh coal and adequate water. Allow the fire box to get to cool with too much "new" nuggets and/or having to pump too much water thus cooling the boiler will be cause for a station stop
Ash: make sure the grates have good air flow, might require a poke and rake once in a while other wise the critical space for air flow and capacity for nuggets to be in the bed of hot flames will be lessen

As with any "hands on" keeping elements in balance is an art with balance and a good routine the glow with make you smile with less messing with requirements than one would think is necessary.

BTW- cleaning the fiery dragon is not a difficult task nor that time consuming either. About the same as any other steam locomotive.
