Mark Fecke, P.E., CFEI

Managing Engineer

Thermal Sciences

Professional Profile


Mr. Fecke’s mechanical engineering expertise focuses on steam or hot water generating systems, especially boilers and burners used to generate steam or hot water for electric power utilities, industrial plant utilities, agrochemical and specialty chemical processing plants, hospitals and multi-tenant buildings. He has provided consulting services to clients on most aspects of steam boiler and hot water systems including failure analysis, repairs, startup/shutdown, operation, safety/risk assessment, operator training and performance assessments. Mr. Fecke successfully works with his clients to define complex system problems and to assemble and lead the multi-disciplinary teams often necessary to address these issues.

Mr. Fecke is active in the field of combustion safety including the design and operation of various coal, biofuel, gas, and oil fuel trains, and burner management and combustion control system relating to boilers, furnaces, dryers, ovens, oxidizers, heat exchangers, and radiators. He has assisted his clients in identifying the appropriate level of safeguards necessary for safe operation and control of their systems, the implementation of those safeguards, and auditing their installations. He is well versed in the industry standards and has used those in combination with process hazard analysis techniques to conduct these studies.

In addition to his consulting on various types of combustion systems, Mr. Fecke applies his expertise as a mechanical engineer to the failure analysis and investigation of incidents, with particular emphasis on fires and explosions or failures of valves, pumps, fans compressors, regulators, and other mechanical systems. He has reconstructed incident sequences from various sources of evidence including witness interviews, process measurement data, electronic event logs, laboratory testing, and examinations of physical artifacts. His incident investigations have included fire and explosions or failures of residential, commercial, and industrial equipment.

Besides projects involving combustion systems and incident investigations, he has performed scientific investigations and failure analyses’ on hazardous materials tank cars, induction furnaces, bulk solid and dust handling equipment, chemical process equipment, and rail accidents, He has significant experience operating in confined spaces under supplied air, Level B PPE. Prior to joining Exponent, he worked as a Field Service Engineer for The Babcock and Wilcox Company.
