Focus area 1: incandescent lamps
Focus area 2: The converter furnaces----key
process and high energy consumption compared to
other areas
Focus area 3: The cooling water tower---- water
and wastewater are very critical issues on site.

3.3 Several CP-EE Options and Its Co-benefits
Option 1: incandescent lamps(offices, meeting
rooms, toilets, change-rooms, corridors)
replaced by lamps of energy-saving
6000 lamps ×60 watt/lamp ×8 hours/day × 365days＝1,051,200 kWh
6000 lamps ×15 watt/lamp ×8 hours/day × 365days＝262,800 kWh
=788,400kWh
3.3 Several CP-EE Options and Its Cobenefits(Cont.)
Estimated Benefits:
Cost savings:
788,400kWh × 0.45RMB/kWh-6,000 lamps×8RMB/lamp=306,780RMB
CO2 Emission Reduction:
788400kWh × 0.772tCO2/kmh=609t
Other air pollutants emission reduction
! Considering the total electricity use in 2003 was
742,680,000kWh, how large potential co-benefits are
existing in China!
3.3 Several CP-EE Options and Its Cobenefits(Cont.)
Option 2: Build steam accumulator
Description: The steam system is designed to a maximum operating
pressure of 24.5 kg/cm2, it operates at about 6-8 kg/cm2. This is due to
old and corroded pipe work that causes leaks in the cooling water
piping, especially the furnace’s hood cooling water loop. As a result,
500-600 tonnes of clean steam is vented each day.
The option is to build a steam accumulator on the converter furnace，
using the company’s cogeneration boiler to accumulate heat from the
surplus steam from the current converter furnace to stabilize its
pressure, and it applies to the converter furnace, electric furnace and
VD furnace.

Co-benefits for China are very significant and not to be
ignored.
China has huge potential CDM market, like Shijiazhuang
Iron&Steel Co. Ltd. (Interim Measures for Operation and
Management of Clean Development Mechanism Projects
in China, KP will be effected)
Considering co-benefits, environmental management
policy and climate change policy should be combined.
Main energy intensive sectors, such as cement, iron&steel,
paper, chemicals, should be paid attention to in the
researches on co-benefits .
