Doser mounting system, components and methods

A doser mounting system comprising:

• a mounting plate including an aperture;
• a plurality of fastener brackets coupled to the mounting plate, the fastener brackets positioned about a peripheral portion of the aperture, at least a portion of each of the plurality of fasteners brackets being spaced from the mounting plate, each of the fastener brackets including an opening in the portion that is spaced from the mounting plate;
• a plurality of fasteners each having a fastener head and a fastener shaft positioned in the openings of the fastener brackets such that each fastener head is disposed between the surface of the mounting plate and the portion of the respective fastener bracket that is spaced from the mounting plate, each fastener shaft extending from a respective opening in a direction having an orthogonal component with respect to the surface of the mounting plate;
• and
• a thermal isolator coupled to the plurality of fasteners via the fastener shafts.

A method of coupling a doser system to a doser mounting system, the method comprising:

• coupling a plurality of fasteners to a plurality of fastener brackets coupled to a surface of a mounting plate, the mounting plate including an aperture in the surface of the mounting plate, the plurality of fastener brackets positioned about a peripheral portion of the aperture, at least a portion of each of the plurality of fasteners brackets being spaced from the mounting plate, each of the fastener brackets including a bracket opening in the portion that is spaced from the mounting plate, wherein the plurality of fasteners each have a fastener head and a fastener shaft, and wherein the plurality of fasteners are coupled to the fastener brackets such that a respective fastener head is disposed between the surface of the mounting plate and the portion of the fastener bracket that is spaced from the mounting plate, the fastener shaft extending from the bracket opening in a direction having an orthogonal component with respect to the surface of the mounting plate;
• coupling a thermal isolator to the plurality of fasteners via the fastener shafts;
• coupling a doser to the plurality of fasteners such that the fastener shafts extend through openings in legs of the doser, wherein an injector port of the doser is aligned with the aperture in the mounting plate;
• and
• coupling a plurality of nuts to the fastener shafts, such that the openings in the legs of doser are positioned between the nuts and the thermal isolator and such that a space is maintained between the fastener head and the surface of the mounting plate.
