Abstract
District heating is the current trend in the field of heating. In order to improve the energy efficiency of heating system,and reduce heating costs,this paper put forward four kinds of nature gas district heating schemes based on the different heating modes of existing power plant. The four cogeneration heating schemes were modeled and simulated using Cycle-Tempo. The efficiencies of energy and exergy of each system were analyzed. The main factors influencing the efficiencies of energy and exergy were discussed from the interior of each system. Then this paper established the heating economic model for each scheme and analyzed the main factors affecting the economy. Finally,the influence of the nature gas price,the power price,the heating load and the heating distance on the cogeneration heating systems were discussed.
