Um, luznug, isn't lignite actually brown coal??? I dont generally agree with your posts at all, but let me know if I am missing something here
AKAIK anthracite is black coal, in no way equivalent to lignite - and NSW has some of the cleanest burning in the world (even if some of it is burnt in way below par power stations) - that's why the NSW 38s could be hand fired but only on Hebburn coal or similar and this was also specified for the VR S class prior to oil firing conversion.
Lignite is far far lower in calorific value and also wetter, thus burns far dirtier, only one step up from peat, this is why a proper ETS would be good rather tha what w are being offered at present , force the Vic power stations to either adopt latest drying technologies or else close down and spare us all
Not to question your intentions but coherence and capacity could do with more supporting evidence
Yes Lignite Is commonly know as "Brown Coal" and It Is an young (age)type of coal that has a very high water content In It 70%
The coal It's self Is very soft and loose (like potting mix) It Is very easy to dig out of the ground (no blasting required)
Power station that burn It can only reduce the water content down to about 30% So when the coal Is burnt that 30% water still has to be boiled out before all of the coal can vaporise and this consumes energy (wasted energy)
Loy Yang Power Station was built with four 500 MW units and required boilers that are 105 metres high.
Compare that to Bayswater Power Station that was built with four 660 MW units and only requires boilers that are 80 metres high
That is why Loy Yang Power Station Is the largest Power Station In Australia (but not the most powerful) and Is said to be the most heaviest constructed steel building In the Southern Hemisphere
(the amount of steel In this complex Is daunting)
Once all the water Is extracted out of Lignite coal the coal Is said to be like gun powder with a very high energy value, but to get all the water out Is not a very easy task to do In any commercial quantity
(there Is a plant at Loy Yang that can do this, but I can only produce a very small amount)
