Emissions from Gas Turbine Combustors : Part 2, Analytical Model and Simplified Procedure to Predict NO Emission

A Multiple Inlet Swirler for Gas Turbine Combustors

The central recirculation zone (CRZ) in a swirl stabilized gas turbine combustor has a dominant effect on the fuel air mixing process and flame stability. Most of state of the art swirlers share one disadvantage; the fixed swirl number for the same swirler configuration. Thus, in a mathematical sense, Reynolds number becomes the sole parameter for controlling the flow characteristics inside the...

A Physics - Based Emissions Model for Aircraft Gas Turbine

In this thesis, a physics-based model of an aircraft gas turbine combustor is developed for predicting NO, and CO emissions. The objective of the model is to predict the emissions of current and potential future gas turbine engines within quantified uncertainty bounds for the purpose of assessing design tradeoffs and interdependencies in a policy-making setting. The approach taken is to capture...

Estimating greenhouse gas emissions using emission factors from the Sugarcane Development Company, Ahvaz, Iran

Background: Greenhouse gas (GHG) emissions are increasing worldwide. They have harmful effects on human health, animals, and plants and play a major role in global warming and acid rain. Methods: This research investigated carbon dioxide (CO2) and CH4 emissions obtained from different parts of the Hakim Farabi, Dobal Khazaei, and Ramin factories which produce ethanol and yeast. Seasonal rates ...

Developments of Gas Turbine Combustors for Air-Blown and Oxygen-Blown IGCC

On Accurate and Reliable Anomaly Detection for Gas Turbine Combustors: A Deep Learning Approach

Monitoring gas turbine combustors' health, in particular, early detecting abnormal behaviors and incipient faults, is critical in ensuring gas turbines operating efficiently and in preventing costly unplanned maintenance. One popular means of detecting combustors’ abnormalities is through continuously monitoring exhaust gas temperature profiles. Over the years many anomaly detection technologie...
