A fuel combustion system comprises a discharge nozzle with concentric fuel and air orifices. A fuel conduit is coupled to each fuel orifice for supplying liquid fuel thereto. An air conduit is coupled to each air orifice for supplying air thereto. The fuel and the pressurized air only mixing with one another, upon being discharged from the respective fuel and air orifices, to form a fuel mixture. A supplemental air source supplies supplement air to facilitate combustion. An air deflector sleeve at least partially surrounds and accommodates the at least one discharge nozzle and a cylindrical blast tube surrounding the air deflector sleeve and an outlet end of the cylindrical blast tube supports a flame retention head. The flame retention head redirects the supplement air radially inward, through openings in the air deflector sleeve and the flame retention head, to assist with combustion of the fuel mixture.

A combustion chamber may include a first surface and a second surface interconnected by a wall forming a chamber having a central axis. The first surface may define an exhaust opening and the second surface defining a pilot opening, wherein the exhaust opening and the pilot opening align along the central axis. A plurality of inlet ports may be configured to deliver air to the chamber. A plurality of fuel ports may be arranged on an inside of the second surface to deliver fuel to the chamber. The air flow from the inlet ports and fuel from the fuel ports may oppose each other to create a vortex of product proximal to the second surface.

A system and method for optimizing combustion in boiler. The optimization of the combustion in the boiler involves obtaining various data relating to the flow of fuel and air to burners of the boiler and the flame in the burner zone of the boiler that is generated from the introduction of the fuel and air into the burner zone. The data is used to determine air flows to the burners. The data and air flows are used to balance air and fuel at individual burners by manipulating air to match the fuel flow. The balancing of air and fuel at individual burners by manipulating air to match the fuel flow uses a guided search optimization algorithm that mixes stoichiometry determinations with a custom search algorithm that accounts for measurement inaccuracies and unexpected interactions between burners.
