TEAM UP!FOR Waste-Heat AND
Recovery SAVINGS
It can be as easy as re-using hot exhaust
air.

Why should we care?
For the environment
For the bottom line

Why should we care?
For the environment
Re-using hot exhaust air uncovers energy savings.

Why should we care?
For the bottom line
Re-using hot exhaust air saves money.

What are the sources?
Usable energy may be available from
Hot flue gases Hot or cold water
drained to a sewer Exhaust air Hot or cold product or
waste product

What are the sources?
Usable energy may be available from (cont.)
Cooling water or hydraulic oil Ground-source thermal energy Heat collected from solar panels Superheat and condenser heat
rejected from refrigeration equipment

What factors should be considered?
How does the supply compare with demand? How easily can the waste-heat source be
accessed? How far is the source from the demand? What’s the quality of the waste heat? Are there any implications for product quality? How much upgrading is required? Are there any regulatory limits? What will the payback period be?

What can we do?
1. Housekeeping2. Low-cost

What can we do?
1. Housekeeping Inspect and maintain equipment to
minimize the production of waste heat.
Identify sources of waste heat. Eliminate as many sources of waste
heat as possible.
Reduce the temperature of the remaining waste heat.

What can we do?
2. Low-cost opportunities Capture waste heat from a clean waste
stream that normally goes into the atmosphere or down the drain, and then pipe the waste stream to where it can be used.
Re-use hot exhaust air for drying.

What can we do?
2. Low-cost opportunities (cont.)
Use waste-process water as a heat source for a heat pump.
Use the heat of the plant effluent being treated in a wastewater treatment facility as a heat source for a heat pump.
![Page 12: TEAM UP! FOR Waste-Heat AND Recovery SAVINGS It can be as easy as re-using hot exhaust air.](https://reader036.fdocuments.in/reader036/viewer/2022072006/56649d205503460f949f4460/html5/thumbnails/12.jpg)
What can we do?2. Low-cost opportunities (cont.) Install improved automatic
controls. Re-use heat from cooling hydraulic
oil (e.g. within moulding machine and the injection moulds themselves). This reduces the electrical load on the production process as well.
![Page 13: TEAM UP! FOR Waste-Heat AND Recovery SAVINGS It can be as easy as re-using hot exhaust air.](https://reader036.fdocuments.in/reader036/viewer/2022072006/56649d205503460f949f4460/html5/thumbnails/13.jpg)
What can we do?3. Retrofits Install waste-heat reclamation
equipment (e.g. replace a cooling tower circulation loop with a shell-and-tube heat exchanger).
Upgrade or replace outdated waste-heat reclamation equipment.
![Page 14: TEAM UP! FOR Waste-Heat AND Recovery SAVINGS It can be as easy as re-using hot exhaust air.](https://reader036.fdocuments.in/reader036/viewer/2022072006/56649d205503460f949f4460/html5/thumbnails/14.jpg)
What can we do?3. Retrofits (cont.)
Recover flue gas heat and use it as a heat source for a heat pump.
Use an absorption heat transformer, which reclaims waste heat using a solution of lithium bromide.
Integrate a compact heat exchangerwith other processes.
![Page 15: TEAM UP! FOR Waste-Heat AND Recovery SAVINGS It can be as easy as re-using hot exhaust air.](https://reader036.fdocuments.in/reader036/viewer/2022072006/56649d205503460f949f4460/html5/thumbnails/15.jpg)
What can we do?3. Retrofits (cont.) In a large computer centre, capture
generated heat by using thermal storage. Recover heat generated through
refrigeration and upgrade it using a heat pump.
Convert high-temperature flue gas heat (e.g. from metallurgical furnaces) into superheated steam for electric power generation.

How can we do it?
We have the people.We have the tools.

Thank you
Together we can make it happen.
It’s good for the environment.
It’s good for the bottom line.
