About Waste Heat Recovery

Waste heat recovery is generally associated with the process of capturing emitted waste heat from an industrial site or combustion process and using that wasted heat to generate useful thermal energy.  Nowadays, it is mostly used to produce useful thermal energy or transform it into clean electricity or mechanical power. That is why waste heat recovery for power generation is also known as bottoming cycle CHP or waste-heat-to power.

In fact, it is possible to reduce CO2 emissions as well as the overall energy cost for any plant by simply utilizing this. Besides that, it plays an important role to increase energy efficiency. So, using Waste Heat Recovery is proven extremely beneficial both for the user as well as for our planet also.

There are several ways for using the recovered waste heat. The retrieved heat can be either used within the same operation or transferred to any other operation. That is why a heat exchanger is used in every Waste Heat Recovery process. A heat exchanger is responsible for transferring the heat for heating and cooling processes.  However, there are three essential components required for Waste Heat Recovery and they are:

  • Source of waste heat
  • Recovery technology
  • End-use for the recovered heat

No doubt, Waste Heat Recovery provides one of the easiest and most cost-effective ways to boost the overall energy efficiency for any industrial, large commercial, and institutional applications. The basic idea behind Waste Heat Recovery is to capture the wasted heat from one part and re-use as much of it as possible in other applications. So, it is possible to transfer the surplus heat from any industrial plant to district heating in an energy-efficient manner with the help of a heat exchanger.

As per a recent report from the United States Department of Energy, approximately 50% of the energy generated from all fuels burned ends up in our atmosphere as waste heat. It also states that the recovery of wasted energy from industrial and large commercial sectors can fulfill 20% of total domestic electricity demand and result in a 20% reduction in greenhouse gas emissions.

Nowadays, Waste Heat Recovery technology is widely used in marine propulsion systems. No doubt, approximately 50% of fuel’s energy content is lost mainly due to the excessive heat even with the current conventional two-stroke propulsion power plant. By including a Waste Heat Recovery system in the ship’s main propulsion plant, it is possible to utilize the fuel more efficiently since it lowers the energy loss in the exhaust gas flow.  

So, implementing a Waste Heat Recovery system can provide numerous benefits including:

  • Reduces the overall operating costs
  • Decreases the overall energy consumption
  • Aids in reusing dangerous emissions

So, investing in a waste heat recovery system is probably one of the most logical investments a facility can make.
