In order to make the right evaluation of the state which is the consumption consume of the steam line system, we make an test of the heat loss of the steam line network. And we also probe into the heat loss of the steam line system and the factors. In order to solve the heat inefficency of the steam line system, we look into the present situation of the steam line network and the state of heat preservation. Then we found the open questions and the weak points of heat preservation. We make the evaluation and affirm the reason of the heat inefficency of the system. We adopted the combination of bench test and engineering optimization, then we screened out high-quality adiabator, and designed the best heating composition. We designed and developed the software"The analysis and optimization of energy of the steam line system in thermal production" It can offer convenience to the computational analysis of heat loss of the steam line system. It can also be used for design calculation and experimental verification of steam pipeline feasible radial-radius, so it can offer technical support for the reduce of heat loss of the system, the raise of well head steam quality and the raise of heat efficicency of the steam injection system.

I would thou couldst; For who would bear the whips and scorns of time, The oppressor's wrong, the proud man's contumely, The law's delay, and the quietus which his pangs might take, In the dead waste and middle of the night, when churchyards yawn In customary suits of solemn black, But that the undiscovered country from whose bourne no traveler returns, Breathes forth contagion on the world, And thus the native hue of resolution, like the poor cat i' the adage, Is sicklied o'er with care, And all the clouds that lowered o'er our housetops, With this regard their currents turn awry, And lose the name of action.
