The Heating System Forms And Economic Analysis Of Regional Gas Boiler Room

Encouraging the development of gas-fired boiler room is an effective measure which ishelpful to environment protect and energy saving, so it is of great realistic significance in cityenvironment and energy structure improvement. This paper firstly explained some calculationmethods of the heat load and their respective characteristics. Based upon the calculation resultof thermal load of each user, the design heat load and average heat load are attained, which isan important basis of deciding on the type, number of boiler and the scale of boiler room.Therefore,accurate load calculation is very important in system design. Secondly, it describedsome heating system forms of the boiler room, and also analyzed their characteristics andusing conditions. Again, it introduced economic analysis method and index of the heatingsystem, and elected dynamic cost method for economic evaluation of the direct primary pumpconstant flow direct connected system,the secondary pump variable-flow direct connectedsystems and the indirect connection heating system with heat exchange stations.Finally,taking the example of a new campus in DaXing, it chose the method of area heat index tocalculate and model the typical building with the help of DeST-h. In a word, the main jobswere to design three different types of heating systems program for the campus, analyze thedifferences among them, and in the end obtain the theoretical results by comparing the projectinvestment and operating costs.
