Secondly, the flow of condensation steam was compared with the flow of ideal gas. From the contrasted results, it can be found the difference between the condensative steam flowing and ideal-gas flowing. And, it also can be found out that it is inevitable to condense for steam flowing under the supersonic state. At the same time, the major areas which formed second drips have been displayed in the solved results. Finally, the flow of condensation steam in the 3-dimension model has been simulated.

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.

According to the running state of the Boiler in Datang Huxian County Second Power Plant, the steam atomizing oil gun was reconstructed to the air atomizing oil gun. The compressed air was used to the atomizing medium of the oil gun that a great quantity of the steam was reduced when the boiler had been no running and steady boiling. Definitely the steam may be supplied by the steam turbine the fourth pulling out section,oil gun's use was not limited by the pressure of the atomizing steam at lower load. It has been realized the energy conservation efficiency function.
