5、iption of the project activity:The objective of Anshan Iron and Steel Group Corporation(Anshan)Coke Dry Quenching Power Generation Project (hereafter referred as the Project)is to install 2 sets of CDQ and Power Generation facilities for recovering the available heat from red hot coke produced by 4

6、coke ovens.The total generation capacity of the project is 24MW(12MW*2),which is expected to deliver 138.480GWh of electricity per year to be consumed entirely by Anshan Iron and Steel Group Corporation(AISG).Currently,there are eleven existing coke ovens at AISG,which used wet coke quenching(CWQ)an

7、d they have been operating very well.AISG accumulated plenty of experience on CWQ.According to the FSR for the project,in the absence of the project activity,wet coke quenching would continue to be used by coke oven No.5,No.6,No.7,and No.8 as well.With this method,the available heat in the red hot c

8、oke is emitted into the atmosphere,when it is quenched by water.The proposed project aims to install 2 sets of CDQ and power generation equipment.The one is for coke ovens No.5(6 meter height)and No.6(6 meter height)with 140t/h coke capacity;the other is for coke ovens No.7(6 meter height)and No.8(6

9、 meter height)with 125 t/h coke capacity.Then the waste heat would be collected and transformed into energy.The electricity supplied by the project will replace the equivalent amount of electricity that otherwise would be imported from Northeast China Power Grid(NEPG),which is dominated by coal-fire

10、d power plants.It is estimated that the project will reduce 137,586 tCO2e per year.PROJECT DESIGN DOCUMENT FORM(CDM PDD)-Version 03.1.CDM Executive Board page 3 Besides the GHG emission reductions,the Project would contribute to local and national sustainable development through:Reduction of air pol

17、logy to be employed by the project activity:The basic principle of CDQ Technology is that the red-hot coke is quenched by circulating inert gases within a closed environment processed by CDQ.The available heat of the red-hot coke will be transferred to the inert gases which generate steam to drive t

18、urbine to produce power.In addition,the installation of dust remover equipment will enable coke powder to be collected and removed,thereby reducing environmental pollution.The CDQ process of the proposed project is illustrated below:Project Location PROJECT DESIGN DOCUMENT FORM(CDM PDD)-Version 03.1

23、ace.The available heat of the red hot coke will be directly exchanged with inert gases(Nitrogen Gas).The red hot coke will be cooled down from about 1000 to 200-250,and then be delivered out of the CDQ furnace by a coke discharger.After the heat exchange(cooling coke),the inert gas is heated 900-950

24、 and it is recycled by a blower.The inert gas is fed into the CDQ boiler to generate steam after being cleaned by the dust remover.Insert gas is cooled down by going through the boiler and it is reused to cool down the heated coke.After the heat is exchanged twice,the heat energy of red hot coke can

37、plicable to the project activity:The methodology ACM0004 is applicable to the proposed project for the following reasons:1.The available heat which is contained in the red hot coke produced from coke oven is collected and used for electricity generation.Therefore,the project belongs to the category

38、of project activities that generate electricity from waste heat in industrial facilities;2.The electricity generated by the project will replace the electricity that would be otherwise imported from the Northeast China Power Grid;3.The project owner,Anshan Iron and Steel Group Corporation,has no pla

39、n to undertake any fuel switch activity in the process where the coke is produced after the implementation of the proposed project activity.B.3.Description of the sources and gases included in the project boundary If the project is not put into operation,power generation from the project will be pro

40、vided by Northeast China Power Grid(NEPG)in which Anshan Iron and Steel Group Corporation is located.NEPG is one of six regional power grids in China,and includes Helongjiang,Liaoning,PROJECT DESIGN DOCUMENT FORM(CDM PDD)-Version 03.1.CDM Executive Board page 9 and Jilin provinces1.According to the

41、methodologyiesACM0004 and ACM0002,the project boundary covers the CDQ furnace,CDQ boilers,steam turbine generation system with its auxiliary system;the energy sources for CDQ system start-up;and the power plants physically connected to the Northeast China Power Grid.The emissions sources which are i

48、DRC on 9th August,2007,http:/ PROJECT DESIGN DOCUMENT FORM(CDM PDD)-Version 03.1.CDM Executive Board page 10 specified(5)Other uses of the waste heat and waste gas Scenario 5:other uses of the waste heat.The main energy demand is from production of iron and steel.However,the steam used in processing

49、 iron and steel must have a high temperature and pressure,above 540,5.3MPa2.The steam generated by CDQ has a temperature and pressure of only 3.82-4.5MPa,450.Thus the steam from CDQ cannot be used in production of iron and steel.Furthermore,because the blast furnace and converter gas are abundant in

50、 AISG and there is an extensive pipe network recovering all the gases needed to meet other uses purpose,it is unnecessary to invest in recovering waste heat from the red-hot coke for other uses which are already met.Therefore Scenario 5 cannot be considered a credible alternative of baseline scenari
