The Central Heating System Operation Practice Research

At present,the central heating system operation adjustment compared with Europeanheating level still exist certain differences.In the face of increasingly tense energy supply,intoday's advocacy of saving energy and reducing consumption,using scientific operationadjustment method,becomes the central heating system operation stability,to reduce thehydraulic imbalance caused by thermal imbalance phenomenon so as to realize the centralheating system is one of the important means of reducing energy waste.In this context,through to the domestic and foreign research on the performance of therelevant information and comparison,combined with an overview of Beijing's central heatingsystem and operation adjustment of basic situation,determine the specific direction of theresearch,also has been clear about the topic of the main research content.This article through to the principle of central heating thermal station operationadjustment of the profound interpretation,combined with the actual situation of city pipenetwork,and analyses the influence of hydraulic imbalance thermal imbalance of the directimpact of,get the heat supply network in the actual operation condition thermal imbalance offour factors,through further study of four kinds of operation adjustment methods advantagesand disadvantages of the relationship,so as to achieve the purpose of to guide the actual work.In view of the city district heating thermal station is based on the supply side to adjustoperation adjustment method,in this paper,the thermal station within the operation frequencyconversion adjustment,water pumps and valves choice,heating substation secondary pipenetwork side USES the adjusting methods of analysis and research,and through the adoptionof balance valve level imbalance phenomenon solve heating buildings,buildings building setmix water system solution to the problem of high-rise building vertical imbalance of practice,the method to solve the problem of the engineering practice.In this paper,through to thepractice of centralized heat-supply system automatic control project,the control strategy,analyzes the implementation effect,sustainable application conclusions are obtained.For Beijing central heating system in recent years are practical demand side adjustmentway,for heat metering method,adopted by the complete renovation project practice effectwas studied,in theory,established the thermal station,secondary pipe network with the userside to adjust the basic linkage,in the future was put forward the direction of further researchis needed in concrete production practice and the conclusion of the sustainable development.
