Abstract

Energy conservation and rational usage of energy is China´s basic national policy. The present steam consumption and heat loss of its pipeline network in Tianjin airport economic development zone is recorded, then zonal steam distribution efficiency is calculated to be 37.56 % by the steam consumption data, and zonal heat loss is in inverse proportion to steam distribution efficiency with factor of 8.312 × 10⁴ kW, that is, in direct proportion to steam produce, steam enthalpy difference, inverse proportion to steam consumption with factor of 83.12 kW by the steam distribution efficiency, offering reasons to optimize steam pipeline network operation, and cover steam requirement with minimal energy consumption.
