Use of waste heat from cement production to generated electricity from cement works in Khairpur
Electricity generated by waste heat.The first Kalina Cycle implementation in cement works.
Starting in 2012, waste heat has been generated during cement production, specifically during the cooling process of clinker and in pre-heater. This heat is used in Kalina Cycle to produce electricity. A solution of two fluids with different boiling points (around 340 °C) allows a maximum heat usage, which overheats the solution. This solution drives the turbine connected to the generator with power of 8.6 MW. The whole system had to be adjusted to be suitable for use in a cement works, but greatly improves its effectiveness.
