Good evening! We tend to say we can get ten days cruising out of a tonne. 4x 25kg bags a day. (one an a 'arf to two hundredweight) - Emilyanne holds about 1.5t, which is about 12days or so, without grovelling out the last dozen bags worth from the back of the bunker.
On a river you will clearly use more than that. Possibly even twice as much, if you going for it, against the tide. - But at the same time, a heavy day of locks, and your only really using the bag and a half your lit up with all day. Emilyannes boiler is a little bit marginal for river work (its certainly the limiting factor of overall power output) so when your running hard it does get increasingly less efficient, plus she weighs 22ton, so unless you get her onto fairly open water, your speed is limited anyway. Lower oxford you can forget about averaging 4mph. Coal at the moment is an interesting topic, where just working out what we burning next. About 10 years ago we bought about as many tonnes, palletised in 25kilo sacks. Which dry stored, we've been using basically since. We now have 10 sacks left. - I think back then we paid a close to £100/tonne as anything else for some very burnable polish coal. - Looking around now, you can pay upto £250/tonne. However the current plan seams to be to mix some columbian bituminous housecoal with some chinese anthracite. And see how it goes. Closer to £150/ tonne. Daniel
