Eligibility Criteria
13
Criterion 1 The project utilizes waste heat from a cement production facility by waste heat recovery system (WHR) to generate electricity
Criterion 2 WHR system consists of a Suspension Preheater boiler (SP boiler) and/or Air Quenching Cooler boiler (AQC boiler), turbine generator and cooling tower
Criterion 3 WHR system utilizes only waste heat and does not utilize fossil fuels as a heat source to generate steam for power generation
Criterion 4 WHR system has not been introduced to a corresponding cement kiln of the project prior to its implementation
Criterion 5 Cement factory where the project is implemented is connected to a grid system and
the theoretical maximum electricity output of the WHR system, which is calculated
by multiplying maximum electricity output of the WHR system by the maximum hours
per year (24*365=8,760 hours), is not greater than the total amount of the
electricity imported to the cement factory from the grid system:
> During the previous year before the validation,
if the validation of the project is conducted
before the operation of the project, or
> During the previous year before the operation of
the project, if the validation of the project is
conducted after the operation of the project
