The Studies Of Model Selection And Configuration Of Sets In District Boiler Houses

As the major infrastructure of heat source in the northern city,district boiler houses is one of the main symbol of a city heating and the development.Industrial boilers,thermal equipment in the regional boiler rooms,their model selection and configuration of corresponding sets mainly aimed at different scale,relating to many problems such as economic,environment,energy and society.In this paper,the present situation and application of research of main coal-burning boiler are summarized, forming a more detailed overview.Under a qualitative comparison,extension superiority evaluation method is introduced into the special heat source.Considering the characteristics of various boiler, we put forward the concept and method of evaluation of the model selection and congfiguration of sets in district boiler houses.Taking example by the index system in the heating, energy, environmental and social aspects, and in view of the actual situation of heating,we establish a comprehensive evaluation index system for the model selection and congfiguration of sets.Taking a central heating project in Harbin for example, using the extension superiority evaluation method based on the index system established, we make a contrast for the four ways from economic, energy, environmental and social aspects. So I reach a conclusion that optimum allocation of choice is 3 boiler in stratified combustion. Additionally, in the same scale of heat with four different ways of burning coal boiler, applying the same assessment and analysis method, we make a comparision among chain furnace, reciprocating grate, pulverized coal furnace and circulating fluidized bed boiler.The evaluation result indicates that chain furnace is preferable to supply of heat in district boiler house.The comprehensive evaluation theoretical model,evaluation index system and evaluation method,which are constructed in this paper,have an important guiding significance for the model selection and configuration of sets in district boiler houses.This research results can be used in other cities'model selection and configuration of sets,and can also provide reference for other similar studies,and provide theoretical basis for relevant policy formulation of government.
