A dual fuel burner system includes a fuel burner housing and a main fuel supply conduit within the fuel burner housing. A main fuel nozzle is positioned proximate to a downstream end of the fuel burner housing and is in fluid communication with the main fuel supply conduit. The main fuel supply conduit is configured to provide 100% of the heat input requirement of the dual fuel burner system. A secondary fuel supply conduit is within the fuel burner housing. The secondary fuel supply conduit is configured to provide 100% of the heat input requirement of the dual fuel burner system. An air circuit is in fluid communication with an outlet of the main fuel nozzle. A direct spark ignitor is positioned proximate to the outlet of the main fuel nozzle.

A wall-fired burner includes a fuel tip defining a fuel direction axis and a fuel tip pivot axis perpendicular thereto. A first air tip is adjacent to the fuel tip. The first air tip defines a first air direction axis and a first air tip pivot axis perpendicular thereto. A second air tip is adjacent to the fuel tip, opposite from the first air tip across the fuel tip. The second air tip defines a second air direction axis and a second air tip pivot axis perpendicular thereto. A mechanism operatively connects the fuel tip, the first air tip and the second air tip for at least one of independent and/or joint movement of the fuel tip, the first air tip and the second air tip.

Provided is a combustion device including: a burner that includes an ammonia injection nozzle having an injection port that faces an inner space of a furnace; and an adjustment structure that adjusts a separation distance between the injection port and the inner space.

A combined combustion burner and a combustion apparatus including the combined combustion burner. The combined combustion burner may include a center tube forming a center passage configured to supply cooling air, a fuel tube surrounding the center tube and forming a fuel passage through which premixed fuel mixed with solid fuel and primary air is sprayed, a secondary tube surrounding the fuel tube and forming a secondary passage through which secondary air is sprayed, and an additional spray nozzle inserted inside the center tube and configured to spray auxiliary fuel containing ammonia.

A frost prevention device for protecting crops in open fields from frost damage. The device may include a housing that encloses both solid and liquid fuel storage compartments, a combustion chamber, a solid and liquid fuel feeding system, and an air intake and exhaust fan. The combustion chamber is configured to burn organic solid fuels or combustible liquids, generating heat to raise the ambient temperature around crops. The device may further include a control unit with thermal and moisture sensors configured to automate its operation based on environmental conditions, and a Global Positioning System module configured to assist in navigating through a field.
