Conceptual carbon-reduction oriented assessment of local flue gas waste heat recovery

Abstract

: The paper is focused on local recovery of flue gas waste heat from industrial combustion equipment (such as process furnaces, water-or steam-boilers, etc.). A simple and systematic assessment is introduced evaluating overall amount of produced carbon dioxide related to a specific option of the available flue gas waste heat recovery (FGWHR). The assessment compares the total CO 2 balance each of locally available option of FGWHR including production of CO 2 associated with the FGWHR system realization and savings of CO 2 associated with the FWGHR system operation. Based on an assessment of the total CO 2 balance of all potentially competitive options of FGWHR applicable in a considered location it is possible to identify the most environmentally friendly option of FGWHR system.
