Abstract


With the development of China 's economy , the central heating utilities has been a great development . Central heating project feasibility studies often encounter the problem of of regional boiler room heating program cogeneration heating program , and cogeneration energy ( coal consumption analysis ) is an important part in the scheme comparison . The general view is that cogeneration high effective energy utilization , more energy , cogeneration units should therefore appeal to large , medium and small simultaneously . But in fact , the longer heating period the majority of the western , northern part of small and medium-sized cities is basically no or smaller industrial and life with the heat load is almost no heat load in the summer , therefore , in this case , the cogeneration not necessarily reflect its energy-saving advantage . In view of this situation , this paper, coal consumption analysis based on modeling energy consumption analysis , of several common scale district heating boiler room , as well as cogeneration corresponding coal consumption compare technical indicators to compare results Computational analysis obtained in the case of only heating load (ie the actual heating load ) , small and medium-sized cities of China 's western and northern regions cogeneration program reasonable definition of the value of the maximum load of 145MW energy-efficient than the regional boiler room heating program . This result is similar heating program to conduct a feasibility study has a guiding role . Finally, the actual project - Ulanhot centralized heating program compare heating projects to verify the correctness of cogeneration energy saving defined value .
