Case Comparison of Chinese and Finnish District Heating Substations

Abstract

District heating is developing very fast in China. At the same time, energy consumption for heating is increasing rapidly. To reduce the level of energy consumption, energy conservation measures should be put in place. In Finland, district heating is well established. Both district heating companies and consumers are encouraged to save energy consumption by effective control methods and management measures. From the view of two typical substations in China and Finland, the differences between Chinese and Finnish district heating systems are revealed. The difference in the design and the control method shows the technological shortages. The difference in the pricing system shows the imperfect management system. The Finnish substation gives an example of the modernization substation. The automatic control of the heat substation is the development tendency. Also the Finnish pricing system and management is worth learning to push forward the heat reform in China.
