  • Oxyfuel Combustion in the Steel Industry: Energy Efficiency and Decrease of CO2 Emissions

    Type: 
    Publication
    Publication date:
    Objective:

    Compared with conventional oxyfuel, flameless oxyfuel provides even higher production rates, excellent temperature uniformity and very low NOx emissions. Since its commercial introduction in 2003, the leading supplier has made more than 30 installations of the flameless oxyfuel technology. This chapter describes the state-of-the-art oxygen technologies, including results from installations in the steel industry, and discusses their future possibilities to make steel production more effective.

  • Metal Industry Emissions

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    This chapter of the 2006 IPCC Guidelines for National Greenhouse Gas Inventories gives guidance for estimating greenhouse gas (GHG) emissions from the production of metals. Specifically, it covers emissions from the production of iron and steel and metallurgical coke, ferroalloy, aluminium, magnesium, lead and zinc. It asks for special care in the estimation to avoid double counting or omitting carbon dioxide (CO2) emissions from fuel combustion. It also highlights that CO2 capture and storage is not covered in this chapter.

  • Baotou Iron & Steel Energy Efficiency Project

    Type: 
    Publication
    Publication date:

    The development objective of the Baotou Iron and Steel Energy Efficiency Project for China is to mitigate global environmental impacts of carbon dioxide (C02) emissions through purchase of C02 emissions avoided by the operation of the Baotou Iron and Steel Group Co., Ltd (BISCO) Coke dry quenching (CDQ) project under the clean development mechanism (CDM). The project was approved as a CDM project by National Development and Reform Commission (NDRC) in 2007. It consists of three sets of CDQ heat recovery boilers (No. 1, 2, 3) and steam turbine generators at the back of six coke ovens (No.

  • Technological Learning, Energy Efficiency and Carbon Dioxide Emissions in China"s Energy Intensive Industries

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    Case studies of four energy-intensive industries--aluminum, cement, iron and steel and paper--show how the changes have put these industries on substantially lower carbon dioxide emissions trajectories. Although the changes have not led to absolute declines in carbon dioxide emissions, they have substantially weakened the link between industry growth and carbon dioxide emissions.

  • China’s state-owned enterprises as climate policy actors: the power and steel sectors

    Type: 
    Publication
    Publication date:
    Objective:

    A significant share of China’s greenhouse gas emitting activities is operated by state owned enterprises (SOEs) in power generation and steel production. The report demonstrates that SOEs have played a significant role in mitigation actions in these two sectors. As a wider mitigation-relevant task, the state-owned enterprises have led the modernisation of the steel industry to enable better-quality products aiming at supporting the development of new high-tech sectors, like renewable energy.
