  • Frustoconical combustion chamber for a fluid heating device and methods for making the same
    Patent number: 11906159
    Abstract: The disclosed technology includes a fluid heating device including a frustoconical combustion chamber and a heat exchanger that can include heating tubes. The combustion chamber can have a first end and a second end that is in fluid communication with the heating tubes. The surface area of the second end of the combustion chamber can be larger than the surface area of the first end of the combustion chamber.
    Type: Grant

  • Optimized burners for boiler applications
    Patent number: 11603991
    Abstract: A boiler can have a combustion chamber, a burner, a heat exchanger in fluid communication with the combustion chamber, and a flue for removing a combustion product from the boiler. The burner has a protruding taper shape such as a cone or similar shape. The protruding taper shape of the burner distributes heat to the heat exchanger more evenly than a cylindrical shaped burner thereby reducing heat losses at the combustion chamber wall and increasing the thermal efficiency. The protruding taper shape of the burner also reduces noise associated with the operation of the burner.
