INTEGRATED LOAD BANK AND EXHAUST HEATER SYSTEM FOR A DIESEL GENSET EXHAUST AFTERTREATMENT SYSTEM

摘要

An integrated load bank and exhaust heater for a diesel genset exhaust aftertreatment system of the type having a diesel particulate filter (DPF) and a selective catalytic reduction (SCR) section. The load bank/heater can function as a load bank when testing the genset, as a heat source to optimize SCR efficiency, as to thermally regenerate the DPF filter.

1. A method for operating a control system to control the application of power from a genset to a load bank/heater in an exhaust aftertreatment (AT) system of the type having a selective catalytic reduction (SCR) section coupled to the genset, including:
applying power from the genset to the load bank/heater during genset operation to heat exhaust from the genset; monitoring temperature of the exhaust in the AT system; and regulating the amount of power applied from the genset to the load bank/heater during the genset operation to maintain the monitored temperature of the exhaust in the AT system within an SCR operating temperature range.
