Combined Combustion Required for Energy Fuels

Abstract

The problem of combustion for biofuels with low energy characteristics remains open. The main solution is to approach the combustion of a certain number of biofuels, aiming to capitalize their positive characteristics. It is proved that the combustion of more than two fuels simultaneously usually represents an unnecessary complication. When burning biofuel mixtures, their state of aggregation is of great importance. The combustion of a fuel in a furnace is the result (consequence) of fulfilling a complete set of gas-dynamic and thermal criteria. It is thus possible to achieve the processes of ignition, stable and complete combustion and finally controlled pollutant emissions, possibly to be within certain normal limits. The new range of biofuels of the future represented by wet agricultural waste, wet household waste and low calorific value, animal and poultry waste, sludge, animal fat, biogas from water and sludge treatment, biogas from fermentation of household waste, and gas and pyrolysis of biofuels and solid waste, present countless problems for their use in energy production, as presented in this paper. The generally applicable solution is to burn them in a mixture with another biofuel or fossil fuels. The present chapter highlights the innovative aspect of supporting the combustion of hydrogen-supported biofuels.
