Bottoming cycle type of co-generation:

i) Bottoming cycle of co-generation system is that in which high temperature heat energy is produced using primary fuels. ii) This heat produced is mainly used for other processes except generation of electricity.  iii) Rejected heat from process is utilized to generate electricity. iv) The rejected heat is taken from recovery boiler and it is then applied to the turbine connected to the generator to produce electricity. v) From manufacturing process of some products heat at high temperature is required in furnaces and kilns. vi) After the manufacturing process, the heat rejected or not utilized is also at significantly high temperature which cannot be neglected. And if neglected it will reduce the overall efficiency of the system greatly. vii) Bottoming cycles are suitable for cement industries, ceramic factories etc.
