Thanks to Horslips I think some of the mucis may be
|What do they burn in hell? (14/09/13 17:51:29)||Reply|
"The excess of hydrogen in a coal, above the amount necessary to combine with its oxygen to form water, is known as disposable hydrogen, and is a measure of the fitness of the coal for use in the manufacture of coal gas. Such coal, although of very small value as fuel, commands a specially high price for gas-making. Cannel coal was used as a major feedstock for the historical manufactured gas industry, as the gas produced from it was valuable for lighting due to the luminosity of the flame it produced. Cannel gas was widely used for domestic lighting throughout the 19th century before the invention of the incandescent gas mantle by Carl Auer von Welsbach in the 1880s. Following the introduction of the gas mantle, cannel coal gradually lost favour as a manufactured gas feedstock as the gas mantle could produce large quantities of light without regard for the flame luminosity of the gas burnt."
Hah - when I was a boy back in the 1950ies and 60ies we used coke for heating. We started the fire with wood and paper, then poured coke over it, closed up the oven and let it glow. Coke - porous and rather light, typically the remainder after coal distillation for coal gas manufacture.
My parent told me that coal firing was a real nuisance because of the soot and the smell. The big steam locomotives were coal fired, AFAIK. I remember vaguely something about the smell of their smoke - but that must be 1955 or 1956.
(Ah yes, they were taken out of service in 1957)

(I think I remember that one)
(no idea about the coal quality they were using)

Talking about locomotives if you haven't seen Kray(2010) yet then you want to.
|Heavy oil (19/09/13 17:49:16)||Reply|
Steam valves seems to have been a challenge - to constructors and drivers of the locomotives
Hah - I know the mechanics of the steam engine from elementary school. .no was really backward in the 1960s, ruled as we were of old stalinists (not the police part, but the industry part. Steel, coal, heavy bulk-oriented industries. Margarines from hydrogenated whale or herring oil. Ugly.)
Lots of interesting stuff in Wikipedia - historical and technical.
(All of this because I read in one Lucky Luke magazine that they fired their locomotives with pitch/asphalt/bitumen. I could not find a reference for that, so I suppose coal was the preferred fuel anyway).
|The lighter qualities (21/09/13 21:06:42)||Reply|
(A Burmese that I know of used to say that there are two sorts of winter in Norway: The green winter and the white winter. The green one was the worst, because then the Norwegians turned off the heating.)
Anyway - last winter I let myself be fooled by the tank level indicator, so we ran empty during the worst of the winter. As a preliminary remedy I kept the system running by paying through the nose for "hobby kerosene" - a high-quality lamp kerosene type.
Today I did the annual maintenance on the heater - changing the wick and removing all the coke deposits from the base of the system. I've been doing this for 26 years, and I've never seen deposits like that before.
So one might think that oil products are the same and interchangeable. But no - there are specialised additives for the various uses, and one would not like to be without them.
Plenty room for standard commercial FUD - but maybe sometimes for a reason.
