Waste heat

Heat generated from cement production facility which would
not have been recovered in the absence of the project.

Suspension Preheater boiler (SPboiler)

Boiler which recovers waste heat from a suspension
preheater, which pre-heats raw materials fed into a rotarykiln, to generate steam.

Air Quenching Cooler boiler(AQC boiler)
Waste Heat Recovery system(WHR system)

Boiler which recovers waste heat from an air quenchingcooler to generate steam.
Power generation system consisting of a SP boiler and/or
AQC boiler, turbine generator and cooling tower that utilizes
waste heat from cement production facility.

Items
GHG

emissionmeasures

Summaryreduction Waste heat recovery (WHR) system which generates electricity
through waste heat recovered from cement production facility.
Electricity generated from the WHR system replaces gridelectricity resulting in GHG emission reductions of theconnected grid system.

Calculationofemissions

reference Reference emissions are calculated from net electricity
generation by the project which replaces grid electricity importto the cement factory where the project is implemented during agiven time period.

not utilize any fossil fuel.

Monitoring parameters

The quantity of the electricity supplied from the WHR system tothe cement production facility is monitored.

D. Eligibility criteriaThis methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1

The project utilizes waste heat from the cement production facility by waste
heat recovery (WHR) system 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 heatsource to generate steam for power generation.

Criterion 4

WHR system has not been introduced to a corresponding cement kiln of theproject prior to its implementation.

Criterion 5

The 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 greaterthan the annual amount of the electricity imported to the cement factory fromthe 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 thevalidation of the project is conducted after the operation of theproject.

Criterion 6

The WHR system is designed to be connected only to an internal power grid ofthe cement factory.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissionsReference emissions are calculated on the basis of net electricity generation by the project that
replaces the import of grid electricity to the cement factory where the project is implemented.
The quantity of electricity consumed by the WHR system except for direct captive use of theelectricity generated by itself is subtracted from the quantity of the electricity supplied from theWHR system to the cement production facility to calculate net electricity generation.
In order to ensure conservativeness, the quantity of electricity consumption by the WHR system
except for the direct captive use of the electricity generated by itself, is calculated by using thetheoretically maximum load for the capacity of equipments in the above-mentioned WHRsystem.
F.2. Calculation of reference emissions
REp = EGp * EFgrid

G. Calculation of project emissions
Project emissions are not assumed in the methodology as the WHR system utilizes only waste
heat and does not utilize fossil fuels as heat source to generate steam for power generation,
which is prescribed in the eligibility criteria 3.
Therefore, the following formula is used to express the project emissions:
PEp = 0H. Calculation of emissions reductions
Emission reductions are calculated as the difference between the reference emissions andproject emissions, as follows:
ERp ＝ REp - PEp
