A heating apparatus and method for use in an exhaust gas system is provided that includes a container body defining an exhaust gas pathway, a heater flange component attached to an exterior of the container body, and a heater assembly disposed in the exhaust gas pathway and secured to the heater flange component. The heater assembly includes at least one heater element, a bracket assembly that secures the at least one heater element in the container body, and a conformal bracket for securing the at least one heater element to the bracket assembly.

Exhaust gas heating apparatus

A method of controlling a heating system is provided that includes having at least one heater assembly, the heater assembly comprising a plurality of heater units, each heater unit defining at least one independently controlled heating zone, supplying power to each of the heater units through power conductors electrically connected to each of the independently controlled heating zones in each of the heater units, and modulating power supplied to each of the independently controlled heating zones. A voltage is selectively supplied to each of the independently controlled heating zones such that a reduced number of independently controlled heating zones receives the voltage at a time, or at least a subset of the independently controlled heating zones receive a reduced voltage at all times.
