- In the bottoming cycle, cogeneration system fuel is burnt mainly to produce useful heat, unlike the previous system.
- Then rejected heat in this process is recovered by heat recovery boiler and associated turbine generator to generate electrical power.
- This system proves suitable for manufacturing processes which demand high-temperature heat for it and exhausts heat at high temperature as well.
- In this, leftover gases from existing plant process are recovered to generate electricity.
Some of the applications areas are steel industries, cement industries etc.
