Water and Fire plus muscle and sweat. (And these days, passion and enthusiasm!) :)

But I'm worried about the wood needed for a steam train. Where to get it? Forests? :shock:

Welcome back Alec, Steam Trains burn coal by the way. :)

Thanks, Twilightcapers.

Good point, yes, coal.

In the USA, "clean coal" is a political football as the question of "reliance on fossil fuels" comes up. One side's candidate or the other will make a speech and "clean coal" will be mentioned, rattled off in a litany of promises ...

Coal is quite a problem.

Coal is quite available in Australia and in Germany.

A funnel of steam is so much more attractive than a funnel of smoke and seems less polluting -- appearance-wise -- to this particular beholder. 8) :wink:

Coal is indeed a problem if it is burned. (Absolutely no offence meant to our Dreamsville miners) But the term 'Clean coal' is a deceptively complete misnomer. There is nothing clean about it. It's just an attempt to 'gussy-up' regular old coal. But at an astronomical price. Coal is coal, what clean coal claims is a new technology which 'captures' pollutants from the burning of coal before they are introduced into the atmosphere. Sounds impressive.

But the few remaining steam trains are not much of a problem. The biggest emissions have always come from the burning of coal in power plants.

Coal is coal


Not quite, within this term lies many different forms & grades, the cheap & nasty stuff gives off many different chemicals I believe,

Quote:
As geological processes apply pressure to dead biotic material over time, under suitable conditions it is transformed successively into:

Peat, considered to be a precursor of coal, has industrial importance as a fuel in some regions, for example, Ireland and Finland. In its dehydrated form, peat is a highly effective absorbent for fuel and oil spills on land and water. It is also used as a conditioner for soil to make it more able to retain and slowly release water.
Lignite, or brown coal, is the lowest rank of coal and used almost exclusively as fuel for electric power generation. Jet, a compact form of lignite, is sometimes polished and has been used as an ornamental stone since the Upper Palaeolithic.
Sub-bituminous coal, whose properties range from those of lignite to those of bituminous coal, is used primarily as fuel for steam-electric power generation and is an important source of light aromatic hydrocarbons for the chemical synthesis industry.
Bituminous coal is a dense sedimentary rock, usually black, but sometimes dark brown, often with well-defined bands of bright and dull material; it is used primarily as fuel in steam-electric power generation, with substantial quantities used for heat and power applications in manufacturing and to make coke.
"Steam coal" is a grade between bituminous coal and anthracite, once widely used as a fuel for steam locomotives. In this specialized use, it is sometimes known as "sea-coal" in the US.[11] Small steam coal (dry small steam nuts or DSSN) was used as a fuel for domestic water heating.
Anthracite, the highest rank of coal, is a harder, glossy black coal used primarily for residential and commercial space heating. It may be divided further into metamorphically altered bituminous coal and "petrified oil", as from the deposits in Pennsylvania.
Graphite, technically the highest rank, is difficult to ignite and is not commonly used as fuel — it is mostly used in pencils and, when powdered, as a lubricant.
The classification of coal is generally based on the content of volatiles. However, the exact classification varies between countries. According to the German classification, coal is classified as follows:[12]

German Classification English Designation Volatiles % C Carbon % H Hydrogen % O Oxygen % S Sulfur % Heat content kJ/kg
Braunkohle Lignite (brown coal) 45–65 60–75 6.0–5.8 34-17 0.5-3 <28,470
Flammkohle Flame coal 40-45 75-82 6.0-5.8 >9.8 ~1 <32,870
Gasflammkohle Gas flame coal 35-40 82-85 5.8-5.6 9.8-7.3 ~1 <33,910
Gaskohle Gas coal 28-35 85-87.5 5.6-5.0 7.3-4.5 ~1 <34,960
Fettkohle Fat coal 19-28 87.5-89.5 5.0-4.5 4.5-3.2 ~1 <35,380
Esskohle Forge coal 14-19 89.5-90.5 4.5-4.0 3.2-2.8 ~1 <35,380
Magerkohle Nonbaking coal 10-14 90.5-91.5 4.0-3.75 2.8-3.5 ~1 35,380
Anthrazit Anthracite 7-12 >91.5 <3.75 <2.5 ~1 <35,300
Percent by weight

The middle six grades in the table represent a progressive transition from the English-language sub-bituminous to bituminous coal, while the last class is an approximate equivalent to anthracite, but more inclusive (US anthracite has < 6% volatiles).

Cannel coal (sometimes called "candle coal") is a variety of fine-grained, high-rank coal with significant hydrogen content. It consists primarily of "exinite" macerals, now termed "liptinite".


The UK deposits are some of the best grade Coal in the world.

Steam Locomotives were most often Coal Burners but Wood was also used as a fuel particlarally in forested areas and as an attempt to lower maintenence costs in the later years of the Steam era many Locomotives were converted to burn Oil

The main reason for the demise of the Steam Train was that they were labour intensive to operate........ Countries with low labour costs such as India ran Steam trains for far longer than Countries in Europe and in the US.

Coal is a dirty fuel and the lower the grade of coal the dirtier it is in terms of emissions when it is burned. At the moment Australia generates a lot of it's electricity by burning Coal, we have huge deposits of the stuff, some of it very polluting "Dirty" Brown Coal. Australia is also digging the stuff up as fast as possible and selling vast shiploads of it to China to fuel their economic boom......... a worrying situation if you believe that man made pollution is affecting the atmosphere.......

The burning of Coal or any other fossil fuels at an ever increasing rate does seem to be one of the Human Race's most misguided practices........

The race is on......... to either use up all the Earth's resources or to kill ourselves off by making the place unihabitable....... either way we lose.

And
The way we're going
earning a living from a career in music may not be a problem for much longer..........

NOT IN MY NAME


Not a big fan i must admit of Nitrogen Dioxide as it goes but i am a fan of a coal powered steam engines i stand over the bridge at Haworth and pelt my nose and face with THAT AROMA! If it could be bottled i should wear it's essence with pride!! :lol:

And my REGULAR earstuds are JET From Whitby cliffs! :lol:

Any chance you work for a newspaper, James? :lol: :wink:
