The heatn0t p8rt is made up of the first nct and the second nat . by regulatng the valve of the first - net water - supply pipe , we can chmp the flux in the firstnet watersupply pipe in order to guaramee the supplied watcr ' s temperature of the second - not . in this text , according to the analysis of heat - supply condition of our country , we adopted the disttibute type and concentratc control of " suppleness cotltrol " system 世界上比较成熟的供热模式有前苏联模式和东欧模式，我国结合自己的实际国情，大部分城市集中供热系统采用仿东欧模式，整个供热系统由由热源和热网两个部分组成，热源为热电厂供热，热网部分保证热量的均匀分配，热网又分为一次网和二次网，通过调节一次网供水管的调节阀，改变一次侧的供水流量，从而保证二次侧的供水温度。
The present situation of the automatic technology application of the centralized heating system is reviewed in this paper , especially the running situation and problems of automatic control system of the heat - exchanger unit in the thermal station , the important significance of designing new type computer control system of the heat - exchanger unit is expatiated 论文回顾了我国集中供热系统自动化技术的应用现状，尤其是热力站换热机组自动控制系统运行的情况和存在的问题，阐述了对其进行新型计算机控制系统设计的意义。
Taking dalian dye and chemicals co ltd . self thermoelectric plant as an example , this passage has entered on the following discussion on the technical analysis of energy saving and benefit on environment protection . ( 1 ) in view of china ' s present conditions of energy using and taking coal as the main energy supply , the method of concentrated heat supply of the thermoelectricity cogeneration has a great benefit on saving energy and environment continuing development 本文以大连染料化工集团公司自备热电站为例，对热电联产集中供热系统进行了节能技术分析与环保效益评价，具体进行了以下方面的研究： ( 1 )根据我国能源利用现状及燃料供应以煤碳为主的特点，热电联产集中供热方式具有明显地节能和环保效益，是实现可持续发展的重要手段和措施。
With the quickly development of the city construction and economy , environmental protection and saving energy become more and more importan . the city concefltfation heat - supp1y also become the trend to the city pndicularjy to the north city how to make the conc0foraton heatsupply system run in good status with high efficiency become a necessary problem to be resolved 随着城市建设和经济的飞速发展，环境保护和节约能源成为越来越重要的问题，城市集中供热也成为城市尤其是北方城市供热的大势所趋，如何使整个集中供热系统处于一个良好的、高效的运行状态，成为供热控制系统所必须解决的问题。
This paper takes the central heating system of heating company in shihezi city as its research object . on the basis of basic heating theory , the computer applications technology , the central heating system was analyzed and studied . according to the characteristics of collect heating system , the computer control mechanism and method are developed 本文以石河子热力公司集中供热系统为研究对象，以供热工程基本理论为基础，结合当前的计算机应用技术，对集中供热热力站微机监控系统进行了分析和研究，针对集中供热系统的特点，提出了微机监控原理及方法，设计了热力站微机监控系统。
