A method for converting agricultural biomass or industrial bio waste into biofuel using concentrated radiated energy is disclosed. Biomass or bio waste is stored inside a batch reactor in either solid or semisolid state. Unwanted moisture and unwanted oxygen are removed from the stored agricultural biomass or industrial bio waste. Concentrated radiated energy is directed towards the biomass or bio waste through a radiated energy concentrator that focuses the concentrated radiated energy. Biomass or bio waste is kept within the depth of focus of the concentrated radiated energy during the conversion operation. Due to substantial matching of the absorption peak of biomass or bio waste with the emission peak of the concentrated radiated energy, the biomass or bio waste that is within the depth of focus instantaneously decomposes into biofuel. The biofuel thus generated is at ambient temperature with higher energy density.

A radiant burner for treating an effluent gas stream from a manufacturing processing tool includes: a porous sleeve at least partially defining a treatment chamber and through which treatment materials pass for introduction into the treatment chamber; and an electrical energy device coupled with the porous sleeve and operable to provide electrical energy to heat the porous sleeve which heats the treatment materials as they pass through the porous sleeve into the treatment chamber. In this way, electrical energy, rather than combustion, is used to raise the temperature within the treatment chamber in order to treat the effluent gas stream.

A coal combustion process is described using cleaned coal and processed biomass to reduce adverse by-products in a coal combusting apparatus including the reduction of carbon dioxide by at least 50 volume %. The coal feedstock comprises an aggregate blend of cleaned coal and processed biomass. The biomass feedstock comprises processed biomass pellets. The total energy density is predetermined and can be similar to the coal component or higher than the coal component. The intracellular salt in the processed biomass is at least 60 wt % less for the processed organic-carbon-containing feedstock used to make the processed biomass pellets than that of the starting un-processed processed organic-carbon-containing feedstock. The cleaned coal has a sulfur content that is 50 wt % less than that of un-cleaned coal before it passed through the coal-cleaning sub-system.
