HEAT RECOVERY

Tri-Tech has been involved in the engineering for a variety of energy-savings and energy-recovery efforts for many of their large industrial and institutional clients. Energy projects have included ice storage systems (for off-peak electrical savings), cooling water conservation (vs. once-thru cooling water), energy recovery ventilators (for large areas of asembly), and heat recovery from oven flue exhausts (as discussed hereafter).

During the past two years, Tri-Tech has been involed in the heat recovery engineering for a large food processing manufacturer. This effort has included the engineering for various baking processes in several plants nationwide. To accomplish energy savings in these baking processes, heat recovery from each oven's flue is attained through air-to-air heat transfer, then it is re-introduced into the same oven's combustion air intake. Though the task seems very straight forward, a series of engineering procedures are required to justify each project's cost.

Tri-Tech engineers visit the site and take various readings at the equipment where heat recovery and energy savings are desired. This information is used to determine the feasibility and estimate the payback (or return on investment). The recovery effort requires an up-front capital expentiture which includes preliminary on-site testing, energy savings calculations, feasibility reports and cost estimates, engineering and installation drawings, and mechanical equipment installation and start-up. After the installation, additional testing is performed to verify and quantify the actual savings.
