Boiler Fuels, Emissions and Efficiency - CED Engineering
Discussions that follow focus on fuels commonly fired in boilers to generate steam or hot water, atmospheric emissions associated with fuel combustion, and factors that influence how effectively the energy content of the fuel is transferred into usable heat. 3.1 FUELS Many different solid, liquid, and gaseous fuels are fired in boilers.

High efficiency hydrogen evolution from native biomass
Protons from biomass diffuse to the cathode and are reduced to hydrogen. The electric energy consumption could be as low as 0.69 kW h per normal cubic meter of H 2 (Nm 3 H 2 ) at 0.2 A cm 2, which is only 16.7% of the energy consumed for the reported water electrolysis.

How can we increase the efficiency of the boiler in - MEEE
If the fuel has a high moisture content, the enthalpy losses taking place will be much higher and thus the efficiency of the boiler will without a doubt come down. For solid fuel-fired boilers, drying the fuel before combustion can prevent losses of enthalpy which results in improving the boilers efficiency.
