An exhaust treatment system is provided. The system may include a particulate trap configured to remove one or more types of particulate matter from an exhaust flow, the exhaust flow including at least a portion of a totality of exhaust gases produced by an engine. The system may further include a burner assembly configured to increase a temperature of gases in the exhaust flow at a location upstream from the particulate trap. The burner assembly may include an exhaust inlet oriented in a direction along a first axis and configured to direct the exhaust flow into the burner assembly and an exhaust outlet oriented in a direction along a second axis at an angle relative to the first axis, the exhaust outlet being configured to direct the exhaust flow out of the burner assembly toward the particulate trap.

What is claimed is: 1. A method of regenerating an exhaust particulate trap, comprising:directing an exhaust flow, produced by an engine, into a burner assembly, the exhaust flow including at least a portion of a totality of exhaust gases produced by an engine, the burner assembly being located upstream from a particulate trap configured to remove one or more types of particulate matter from the exhaust flow;directing the exhaust flow through a plurality of holes in an exhaust flow distribution member and thereby substantially evenly distributing the exhaust flow about a combustion chamber member to remove heat from the combustion chamber member, the heat being created by a flame within the combustion chamber member;heating the exhaust flow in stages as the exhaust flow passes through the burner assembly by exposing a portion of the exhaust flow to the flame at a first stage and exposing additional portions of the exhaust flow to the flame at each subsequent stage to create a heated exhaust flow;directing the heated exhaust flow out of the burner assembly and to the particulate trap to thereby increase a temperature of the particulate trap.
