I couldn find the specific heat capacity of water in the env data book. Is this 4.1868kJ/kg/K?
The specific heat of water is indeed 4.1868 kj/kg/degC and it is in the Data Book on page 113 of the 2004 edition. The page number may be slightly different for the 2005 edition available in the exams, but it will be the first page of the Energy Section. • Co-firing- this is where biomass is burned in combination with another fuel (coal?) in a coal fired power station isn’t it? Or can it apply to just biomass being burnt in a coal fired power st (without the coal)? Co-firing can be used when more than one fuel is used in a pwoer station – some stations can burn a combination of coal and oil (or gas). Most coal fired power stations require some oil firing or gas firing to start – this owuld not normally be classified as co-firing. Co-firing would be the deliberate mixing of fuels. This can be beneficial if one fuel is in short supply – e.g. in the miners strike in 1985. More recently it has been used in conection of burning biomass in fossil fuel power stations. The rational behind this
