Pressurized Recuperator For Heat Recovery In Industrial High Temperature Processes

Abstract

PRESSURIZED RECUPERATOR FOR HEAT RECOVERY IN INDUSTRIAL HIGH TEMPERATURE PROCESSES CIŚNIENIOWY REKUPERATOR DO ODZYSKU CIEPŁA Z PRZEMYSŁOWYCH PROCESÓW WYSOKOTEMPERATUROWYCHRecuperators and regenerators are important devices for heat recovery systems in technological lines of industrial processes and should have high air preheating temperature, low flow resistance and a long service life. The use of heat recovery systems is particularly important in high-temperature industrial processes (especially in metallurgy) where large amounts of thermal energy are lost to the environment. The article presents the process design for a high efficiency recuperator intended to work at high operating parameters: air pressure up to 1.2 MPa and temperature of heating up to 900°C. The results of thermal and gas-dynamic calculations were based on an algorithm developed for determination of the recuperation process parameters. The proposed technical solution of the recuperator and determined recuperation parameters ensure its operation under maximum temperature conditions.

Modification of a recuperator construction with CFD methods

“…These characteristics enable installing them in locations inaccessible for traditional units, that often have oversized constructions. Examples of such difficult locations may be ceilings with a small load capacity, some areas of chimneys or even gas transport channels (Gil et al, 2015).…”
