Frequently Asked Questions:

1] How does the waste heat recovery system work?
Ans. The system works by directing the furnace's exhaust gases into a case containing refractory material such as aluminum oxide. The heat energy from the exhaust is recovered and stored as the exhaust gas heats up the aluminum oxide media.

2] What is waste heat recovery?
Ans. "Waste heat recovery" is the process of reusing heat energy that would otherwise be discarded or simply released into the atmosphere. Plants can reduce energy costs and CO2 emissions while increasing energy efficiency by recovering waste heat.

3] What are the benefits of waste heat recovery?
Ans.Waste heat recovery reduces fuel consumption, which reduces the amount of flue gas produced. As a result, the equipment sizes of all flue gas handling equipment, such as fans, stacks, ducts, and burners, are reduced.

4] Can consumers put a heat recovery system in an old house?
Ans. A ProAir system can be retrofitted into an existing home. It would be a particularly good time to consider installing an MVHR system when improving insulation levels or doing other improvement work. When major renovations are carried out, the job is nearly identical to that of a new build.

5] Can waste heat generate electricity?
Ans. Bottoming cycle CHP—another term for WHP—can use waste heat streams to generate electricity. 1 In this configuration, fuel is first used to provide thermal energy, such as powering a furnace, and then the waste heat from that process is used to generate power.
