Energy efficiency is a strategic objective in the majority of world countries. However, there are still many industrial facilities that operate with substantial energy losses due to underutilization of gas heat generated during production processes. Simply because the heat is either used inefficiently or is not used at all, energy losses occur on a factory – wide level.
Energy efficiency solution offered by ECAT Company is heat recuperation. It is a heat exchange process that involves heat transfer from exhaust to fresh pressurized air. Heat recuperation system can act as a core module of catalytic gas emissions abatement system or can be operated as. a standalone equipment unit.
Heat recuperation system consists of plate heat exchanger. Heated gas as well as cool air from inlet ventilation go through it. Heat exchange bay consists of profiled plates.
General configuration of recuperator
ECAT Company provides the following services: heat recovery calculation, economic calculation, design of heat exchange modules mounting in ventilation system as part of catalytic gas emissions abatement system or independent from it.
Methods of calculation of heat recovery and resistance to gas flow allow to design, manufacture and commission high-performance custom equipment that fully complies with technical design specification.
