In recent years, the continuous deterioration of the air environment, haze, dust weather increased more frequently, the government has increased investment in air pollution, several air pollution indicators, such as total suspended particles, dust, sulfur dioxide, nitrogen oxides, North City is higher than the South City, heating period is more than the non heating period. Air pollution in heating period is generally more than the standard, the basic reason is that the heat of the coal is released from the pollutant. In the future, more and more heating buildings, the release of pollutants is also growing, and environmental indicators are getting worse. Therefore, one of the important measures to improve the air quality is to develop urban central heating.This article will explain the deep connection between the heat source and the heat supply operation, so that more people engaged in the heating of the central heating to consider the problem from a new point of view for more people to provide operational experience reference.First of all, this paper will focus on the advantages and disadvantages of various operating modes of multi heat source heating system is discussed, according to the actual situation of Dalian City, to determine a mode of operation, combined with the power network of Dalian heating company actual operation, the hydraulic imbalance problem of the optimal operation mode of heat load, the temperature distribution of water flow and operation the research of the establishment of mathematical model; hydraulic analysis, in charge of the network and the large branch for hydraulic calculation, the hydraulic calculation combined with the conclusion of the targeted technological transformation to heating network, rely on operation data scheduling platform of large power heating company after the completion of the hydraulic balance adjustment work, considering the people’s livelihood the effect of the heat exchange station, the optimal flow allocation table, provide convenience for adjusting network second years in the heating season. |
