Abstract

An emissions control system utilizes otherwise wasted heat to efficiently reduce emissions in a main exhaust flow. Heat stored in exhaust from an auxiliary generator (i.e., auxiliary exhaust) may be used to convert urea to ammonia used by a Selective Catalytic Reducer (SCR) system, and/or the auxiliary exhaust may be used to heat the main exhaust flow before entry into an SCR. Additionally, a heat exchanger may be used to transfer heat from a hot clean flow out of the SCR, to...
