Project Title
Power generation by utilizing Blast Furnace Gas at Mukand
Limited, Ginigera, Karnataka
Country
India
Project description
The proposed project activity of Mukand Limited is to generate
electrical energy from waste gases generated during manufacturing
of pig iron in the Mini Blast Furnaces (MBF). The steel
manufacturing facilities consist of MBFs, Energy Optimizing Furnace
(EOF), Ladle Refining Furnaces (LRF), Vacuum Degassing (VD),
Continuous Casting Machines and Rolling Mills. During the
manufacturing of steel - iron ore, coke and additives are charged
in MBFs. Hot air is passed from the bottom tuyers to maintain a
molten temperature of 1400 degree C. The iron ore is reduced in
presence of coke and fluxes, reducing the iron ore to molten metal.
The molten metal is recovered from the bottom of MBFs. Exhaust
gases in the MBFs are generated, due to the blast provided to the
MBF to facilitate reduction.
The exhaust gases known as Blast Furnace (BF) gases exit from the
top of MBFs through gas cleaning equipment. Particulate matter is
removed from the gas and the gas is cleaned in the gas cleaning
equipment. A stream of the BF gas is utilized for heating the cold
blast and the remaining surplus BF gas is diverted for generation
of power. The BF gas used in power plant is in surplus and would
have been flared up in normal conditions. The power generation
depends upon the availability of BF gas. The power generated will
be used for captive consumption in the steel plant. This will lead
to partial displacement of electrical energy that otherwise would
have been purchased from the carbon intensive grid.
The surplus BF gas (containing CO) in the absence of the project
activity would have been flared to the atmosphere after
pre-treatment. Thus this project activity utilizing this BF gas to
generate power would help mitigate GHG emission.
The project activity applies an approved Consolidated baseline
methodology, ACM0012/Version 02 (Title: Consolidated baseline
methodology for GHG emission reductions for waste gas or waste heat
or waste pressure based energy system); Sectoral Scope 1 and 4 -
Energy industries (renewable-/ non-renewable sources) &
Manufacturing industries.
The project is a Normal Scale CDM project activity with a ten year
fixed crediting period. The starting date of the project activity
is stated to be 09/05/2007.
The annual average emission reductions through the project activity
is 64,477 tons CO2 e. The total Emission Reductions in the fixed
ten year crediting period are expected to be 644,772 t CO2 e.
