Cogeneration energy balancing system

摘要

A system is provided which improves the ability of cogeneration facilities to meet varying electrical power and process steam demands. One or more thermal boosting systems each having a Rankine cycle evaporator coupled with a solution heat pump cycle is integrated with the turbines of the cogeneration facility to maintain full steam flow through the turbines and provide a portion of the process steam demands on the facility. Optionally, a bottoming turbine is added to the system to further improve its flexibility to meet varying demands.
