12:30 (during lunch) Breaking the Heat Recovery Paradox

Peter Garforth

Abstract: Waste heat is an undervalued resource in the glass industry, using valuable fuels, costing money and causing greenhouse gas emissions. Low energy costs have encouraged the industry to accept these losses. However, times are changing and waste heat is increasingly seen as an opportunity, triggering useful low cost actions, such as replacing hot water boilers with recovered heat, pre-heating batch and gas, space heating buildings and various drying applications.

Heat that can be used in these cost effective ways is a tiny fraction of the waste heat, increasingly triggering studies to eliminate or use this excess heat. The only really successful approach to eliminating waste heat is to redesign the process itself, usually technically difficult and rarely cost effective. Occasionally there will be process breakthroughs, but in reality, these are rare, with low energy prices rarely creating the urgency to invest in research.

The obvious alternative is to find uses for the balance of the waste heat, typically as cooling or electricity. Economics normally kill these projects. This is the paradox. Vast amounts of valuable fuel are wasted as heat. Cost effective uses in a typical plant are a small percentage of the waste. Capturing and using the balance on site is not cost effective at today's energy prices. Are we condemned to view this excess waste a cost of doing business for the foreseeable future, or could there be another way to look at this unused resource, especially when major capacity expansions or new plants are built?

The presentation will explore the strategic options open to the glass industry, when a new plant or a major expansion is in the works, by teaming with the local community. To retain local employment, communities frequently give generous tax and other incentives. Communities also have growing energy and climate change challenges. By rethinking the energy costs and risks for both the glass plant and the surrounding community there may be creative ways to create significant energy breakthroughs and benefits for both players. Capturing these will require new relationships and new approaches to incentives Instead of the glass plant accepting the heat waste as inevitable, with some creativity the technical, economic and social relationship between the plant and the community can be redefined.
