SYSTEM AND METHOD FOR CONTROL OF EXHAUST GAS RECIRCULATION (EGR) UTILIZING PROCESS TEMPERATURES
First Claim
1. A system, comprising:
- a reciprocating internal combustion engine comprising one or more reaction zones configured to receive a charge flow, wherein the charge flow is configured to react within the one or more reaction zones and to form an exhaust gas flow, and the charge flow comprises an oxidant flow, a fuel flow, and a recirculated portion of the exhaust gas flow; and
a controller configured to control a ratio of the recirculated portion of the exhaust gas flow to a fuel mixture comprising the oxidant flow and the fuel flow based at least in part on a first temperature, a second temperature of the charge flow, and a third temperature of the recirculated portion of the exhaust gas flow, wherein the first temperature comprises one or any combination of a sensed temperature of the oxidant flow, the fuel flow, or the fuel mixture.

Abstract
A system includes a reciprocating internal combustion engine with one or more reaction zones configured to receive a charge flow that is configured to react within the one or more reaction zones, thereby forming an exhaust gas flow, and a controller. The charge flow includes an oxidant flow, a fuel flow, and a recirculated portion of the exhaust gas flow. The controller is configured to control a ratio of the recirculated portion of the exhaust gas flow to a fuel mixture. The controller controls the ratio based at least in part on a first temperature, a second temperature of the charge flow, and a third temperature of the recirculated portion of the exhaust gas flow. The fuel mixture includes the oxidant flow and the fuel flow. The first temperature includes one or any combination of a sensed temperature of the oxidant flow, the fuel flow, or the fuel mixture.
