Abstract
The present disclosure generally relates to the introduction of a liquid biomass in heating systems such as commercial boilers in order to reduce dependence on petroleum-based heating fuel oils as a source of combustion fuel. More specifically, the present disclosure is directed to systems, methods, and apparatuses utilizing a liquid thermally produced from biomass into commercial and industrial boiler or thermal systems such as boilers, furnaces, and kilns, and methods for generating renewable identification numbers (RINs), alternative energy credits (AECs) and renewable energy credits (RECs).
Claims25
A dual-fuel method of heating, comprising:
- i) introducing a petroleum-based fuel into a dual-fuel burner followed by combusting said fuel, wherein the petroleum-based fuel is heating oil;
- and
- ii) combusting an unenriched renewable fuel oil, comprising:
- a) introducing said renewal fuel oil into the dual-fuel burner at a ratio of 1.5:1 to 2:1, on a volume basis, relative to the introduced petroleum-based fuel;
- b) atomizing the unenriched renewable fuel oil in the dual-fuel burner to form a spray cone;
- c) aiming the spray cone proximate a radiant surface to at least partially vaporize the spray cone;
- and
- d) combusting the at least partially vaporized spray cone proximate a heat sink, said heat sink in thermal communication with the radiant surface.

- b) atomizing the unenriched renewable fuel oil in the dual-fuel burner to form a spray cone;
- c) aiming the spray cone proximate a radiant surface to at least partially vaporize the spray cone;
- and
- d) combusting the at least partially vaporized spray cone proximate a heat sink, said heat sink in thermal communication with the radiant surface;
- iii) passing a combustion flue gas through fire tubes of a firetube boiler;
- and
- iv) providing at least one pulse of compressed gas per day to the fire tubes in the direction of flow of the combustion flue gas.
