“…In view of the energy structure reformation in China, on one hand, gas-fired boilers were proposed by some researchers to penetrate into DH in different ways because of the relatively more environment-friendly properties when compared with the other fossil fuels [6][7][8]. With the gas-fired boilers gradually being considered as a reasonable means in heating systems, the DH systems with coal-fired MHSS and gas-fired PHSS are starting to appear [9].…”

In this study, fuel supply optimization model coupled with environmental emission standard and heat demond prediction was applied in the district heating system of a new economic district in the middle part of Liaoning Province. The model results indicate that the coals from different sources and the use of nature gas are influenced while the component ratio of each coal type in coal bending is not influenced by the thermalization coefficient. Moreover, the results also shows that the thermalization coefficient can be regulated by the decision maker of the district heating system, resulting in redistributing the heat supplies between the main heat supply source and peak-shaving heat supply source in order to further obtain the reasonable heating alternative, which has both the economic and environmental merits for the residential users.

“…In this regard, 4th generation DH integrating smart thermal grids [12], thermal energy storage strategies for solar heating systems, and data-driven models for building scale applications are suggested [13].This has made the conflict even more profound on the comparative advantages of energy efficiency between business operators of the CHP-DH system and the SHP system [14][15][16]. Accordingly, several comparative studies have been published claiming comparative advantage of energy efficiency between the CHP-DH and SHP systems [17,18]. The differences between each study for estimating or using specific parameters are listed in Table 1.…”

Energy Efficiency for Supplier and Sustainability for Demand: A Case of Heating Systems in South Korea

et al. 2019

This paper addresses an analysis of a recent debate in South Korea on energy efficiencies between a combined heat and power system with district heating (CHP-DH) and separate heat and power system (SHP) by applying a scenario analysis technique. In accordance with the Low Carbon Green Growth strategy where the rise of social awareness for energy savings is imminent, various scenarios were considered including CHP-DH (excluding waste heat recovery) versus SHP and CHP-DH (including waste heat recovery) versus SHP. To analyze the satisfaction on energy efficiency of each heating system, nationwide average field data were acquired via a survey with the help of the Korea District Heating Corporation (KDHC), and a comprehensive model for measuring sustainable value related to energy consumption, including economic (ECON), non-economic (NECON), and environmental (ENV) values were presented based on customer satisfaction (SAT). As a result of the structural equation model (SEM) and ordinary least squares (OLS) regression, variations of energy efficiencies of each heat and power delivery system are rather distinctive among different scenarios due to the performance characteristics of each system in the field. The energy savings of CHP-DH systems owned by KDHC, based on nationwide average performance, was found to be higher than the SHP system by 3.25% to 18.1%. While the effect of NECON and ENV on SAT was not significant in SHP, it was significant in CHP-DH. Based on these results, rational decisions can be made to lead the government and energy consumers to maximize energy efficiency, especially in South Korea, where the energy market heavily relies on foreign countries.Sustainability 2019, 11, 4216 2 of 21 treaty in Kyoto, parties to the UNFCCC met at conferences to discuss how to achieve the treaty's aims. At the 3rd Conference of the Parties (COP-3), the parties paved the way to reduce greenhouse gas emission effectively and support sustainable development of developing countries by defining three "flexibility mechanisms" which are International Emissions Trading (IET), the Clean Development Mechanism (CDM), and Joint Implementation (JI); the Kyoto Protocol [2].Although South Korea is not bound by the U.N.'s Kyoto Protocol as a first developing (non-Annex I) country, the Korean government voluntarily set a 2020 emissions reduction target to head off an estimated 30 percent rise in emissions compared to the 2020 Business-as-Usual (BAU) emission projection, considering increased national competitiveness and expectations from international society [3]. This goal reaches the highest level of recommendations from the IPCC, showing the strong commitment of the Korean government to join the global movement for coping with climate change. However, the heavy-duty climate change policy of Korean government re-ignited the debate over the effectiveness between combined heat and power systems with district heating (CHP-DH) and separate heat and power systems (SHP), which is a deep-rooted debate in the domestic heating energy indus...
