and operates at 100 lbs per sq. inch pressure.
It is a side fired locomotive type with 101 fire tubes. The boiler can
be fired with coal but for environmental reasons is now fired with
high density wood briquettes made from waste sawdust and wood chips
from furniture manufacturing. This makes 'Alaska' completely carbon
neutral and saves approximately 15 tonnes of carbon dioxide emissions
in a typical year. |
