This site features a list of the most compelling energy auditing projects I have conducted. These projects are presented through industry-inspired applied research papers that have been published in top-tier, peer-reviewed professional journals. Please feel free to contact me to receive a complimentary copy for your personal use.

Energy Audit is a complex procedure of assessing energy streams including energy conversion processes, associated with a manufacturing. An auditor, during the energy audit should be able to identify and quantify them using a unique combination of theoretical knowledge, measurements, estimations, simulations, etc. My energy auditing experience has been summarized in the following publication:

• Kluczek A., Olszewski P., Energy audits in industrial processes, Journal of Cleaner Production (2017), DOI: 10.1016/j.jclepro.2016.10.123

An energy audit I conducted in an energy-intensive corn ethanol plant provided significant thermal improvement opportunities. For the purpose of detailed analysis, a complex mathematical model was developed for a dryer–thermal oxidizer system. The results indicated a major potential for improvement in the following areas: (i) water recovery from humid gas; (ii) heat recovery from moisture condensation, and (iii) fuel savings by reduction of humid gas flow through a thermal oxidizer. I presented detailed analysis, including methodology and results in the applied scientific publication:

• Olszewski P., Heat Recovery Investigation from Dryer-Thermal Oxidizer System in Corn-Ethanol Plants, Applied Thermal Engineering (2015) DOI: 10.1016/j.applthermaleng.2015.02.033

Cogeneration systems are widely used in industrial applications. This case study presents optimization analysis, which I performed for a partially loaded cogeneration, multiple-stages steam turbines system. Owner-developed code (C++) has been used to model turbine characteristics, as well as steam tables and genetic optimizing algorithm. Based on the results three strategies where chosen as the most effective: the first thermodynamic law, energy and exergy efficiency maximization, and total equivalent energy minimization. Optimization methodology and results are presented in the research paper:

• Olszewski P., Genetic optimization of steam multi-turbines system, Applied Thermal Engineering (2014) DOI: 10.1016/j.applthermaleng.2014.06.007
