Abstract

Coal as dominate fuel in China’s district heating (DH) section has brought out a series of environmental, healthy, and economic challenges. Central government
of China makes great efforts to seek better solutions to improve overall DH system efficiency and reduce energy consumption as well as control the emission of pollutants and greenhouse gas (GHG).Optimisation of multi-heat sources such as the collectives of surplus heat from industrial processes, renew energy, combined heat and power (CHP) and heat only boilers (HOBs) for example is a good consideration. Research showed that if surplus industrial heat would be utilized to a great extent, it could cover up to 70% of the heat
demand in northern China’s legal heating regions. In addition, urbanized city areas always have developed DH pipeline infrastructure. The city of Anshan is a great example how industrial surplus heat from the ANGANG (AG) steel plant can be used in the Anshan DH network. Anshan is currently undergoing a major
upgrade of DH system by implementing Scandinavian technology and way of thinking for achieving considerable energy and environmental emission
reductions at the same time as the comfort for the consumers is raised. These could include the establishment of multi-heat sources by utilizing waste
heat, pooled operation and automatic controls applied for the DH systems. This paper will present the inspirations from the Anshan project to illustrate the
potential benefits of China’s DH systems if they are brought up towards the Scandinavian level.
