Development of Optimization Model for Fuel Supply in District Heating System Based on Environment and Heat Demand Joint Constraints

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.
