A.4. Description of the project activity
Ma Steel (old plant) CDQ and waste heat utilization project (below abbreviated as the
proposed project) aims to reduce GHG emissions through installation of two sets of coke dry
quenching (CDQ) systems at the No. 1, 2, 3 and 4 coke ovens in the old plant of Maanshan
Iron & Steel Co., Ltd. (abbreviated as Ma Steel). At present coke wet quenching process
(CWQ) systems have been utilized and a large amount of heat from red-hot cokes emitted into
the atmosphere. The CDQ systems will recover waste heat from red-hot coke produced by
these four coke ovens and utilize the sensible heat for power generation.
The generation capacity of the proposed project is 30 MW. The generated electricity of the
project will be supplied to Ma Steel with an annual net supply of 197.0 GWh, replacing the
equivalent amount of electricity that otherwise would be purchased by Ma Steel from the EastChina Power Grid (ECPG), which is dominated by coal-fired power plants. The expected
emission reductions from the project are estimated at 176,464 tCO2e per year for a fixed
ten-year crediting period.
The project, which recovers waste heat from red-hot coke and then uses the heat for
electricity generation, has significant environmental and social benefits. It contributes to
sustainable development as follows.
The project will reduce the waste of energy resources and promote energyconservation.
Electricity generated by this project will displace coal-fired power generation in theECPG, reducing the environmental pollution generated from burning coal.

A.8.2. Monitoring methodology:
The project has implemented a monitoring methodology developed in compliance with
ACM0004 - Consolidated monitoring methodology for waste gas and/or heat and/or pressurefor power generation for monitoring of CERs. The methodology requires monitoring of the
following:
- Gross electricity generation of the 1# CDQ- Gross electricity generation of the 2# CDQ- Electricity consumption of 1# CDQ- Electricity consumption of 2# CDQ- Steam consumed by the CDQ unit for the de-oxygenizing process- Enthalpy of the steam at certain pressure, saturated temperature
The monitoring meters installation site program is as follows:

The power generated by 1# and 2# CDQ will be transmitted outside via line and line , on
which the electricity energy meters A1 and A2 are mounted respectively to monitor the power
generated by each CDQ.The power consumed by No.1 CDQ will be supplied by line and
line , on which electricity energy meter A31 is mounted. The power consumed by No.2 CDQ
will be supplied by line and line , on which electricity energy meter A32 is mounted. A
part of the power consumed by the two sets of CDQ will be changed from 10kV to 380V
through 324# Substation, and the other part power of 10kV will be directly consumed by the
two sets of CDQ. The four electric energy meters monitoring the electricity generated or
consumed by two sets of CDQ systems will be in 31# Substation.
The electric energy is measured continuously, daily and monthly totals are records as part of
the monthly report.
The steam consumed and the enthalpy of CDQ
Steam consumption supplied by the common steam header to the project activity will be
measured by installing standard steam flow / pressure / temperature metering instruments to
ensure that steam used for the de-oxygenizing process. As the steam is vented after use there
is no need to install equipment to monitor the feedback of steam to the steam header.
The steam consumption is measured continuously, daily and monthly totals are records as part
of the monthly report. The enthalpy data is calculated by the pressure and the temperature of
the steam, the pressure and the temperature are measured daily, and the conservative value
will be used in calculation.
A.9. Calculation Methodology
The amount of CERs that is generated is calculated based on the fundamental CDM equation:
Emission reductions (ER) = Baseline Emissions (BE) Project Emissions (PE) Leakage (L)
The project specific elements of the equation are described below.
Project Emissions
The project activity will consume a small volume of steam which is used in thede-oxygenizing process and subsequently vented into the atmosphere after use. The steam is
supplied by common steam header which draws its steam from a number of sources. These
include waste heat recovery units and coal-fired boilers among other sources.
In accordance with the ACM0004 methodology, project emissions due to the firing of
auxiliary fuels are calculated as below:

between the baseline emissions though substitution of electricity generation with fossil fuels
(BEelectricity,y) and project emissions (PEy), as follows:
