Steam trap is a dynamic process, and inflow temperatures can vary significantly along the wellbore according to the local fluid and rock properties along the well. The location of the hottest spot along the wellbore is static in time. In this approach, a thermodynamic relationship is solved as a well-residual equation to guarantee that the bottomhole temperature (BHT) is less than the saturation temperature of water at the hottest location along the wellbore. A numerical steam trap based on a thermodynamic approach was implemented by Edmunds (2000), and it has been used in simulations with different types of wellbore models in commercial codes. The concept is rather simple (i.e., create a liquid pool around the production well to prevent steam from escaping from the steam chamber into the production well). Steam-trap subcool is a technique that is used to maintain the energy efficiency of the steam-assisted-gravity-drainage (SAGD) process by most heavy-oil producers in Canada. The production of steam RL 014 per day was able to donate a 52.52% or about 73.5 MW of the total needs of PLTP (geothermal power plant) 140 MW per day. Steam trap leaked that needs to be done to combat the most. The drop in temperature in the pipeline will accelerate the condensation, the results of the analysis there is a steam trap leaked is 401.00.17.ST19 and 401.00.05.ST14. The condition of the steam trap is also noteworthy if the steam trap leak then it can lower the temperature in the pipe. The results of the analysis of the pipeline must first and more frequently carried out disposal of condensate on the RL 014 based on pressure drop highest is line DW 14 a and DW 67, next line DW 18 and 17, and the last is the line 11 and 14 b DW. DW Area special analysis was not done against condensation and the number of condensates that are formed so as to indicate the occurrence of condensation done with regular analysis pressure drop in the pipeline. Due to a large number of steam pipelines in the DW area then to do an analysis of pipelines in order to prioritize the disposal of condensate in the pipe more prone formed condensate. The formation of condensate gives a negative impact on production activities both in the pipeline or power plant, thus condensate formed in pipelines should be disposed of via the blow down or steam trap. Condensation can cause problems such as pressure drop. On the process of transmission of steam in the Pipe Line, there are various problems such as condensation in the steam. Geothermal energy from the Earth's magma is manufactured in the form of hot steam. The work is of significance for cavitation control and the optimization design of steam trap valves. The sleeve with smaller diameter orifices, higher installation angle (maximum 80В°) and higher thickness is recommended in practice for better anti-cavitation performance. The improved geometrical parameters of the sleeve are determined to suppress the cavitation inside the valve. Specifically, the orifice diameter of the sleeve has much larger effect on each aspect than that of other two geometrical parameters of the sleeve. The results show that the sleeve parameters have a significant influence on the cavitation intensity and cavitation vapor distributions.

The total vapor volumes are also predicted and compared. The pressure, velocity and vapor distribution inside valves are analyzed and compared for different sleeve geometrical parameters.

In this paper, in order to control cavitation inside steam trap valves, effects of sleeve parameters, including orifice diameter, installation angle and thickness, are investigated using a cavitation model. While flowing through steam trap valves, the condensate water can easily reach cavitation, which may cause serious damage to the piping system. The steam trap valve is used in thermal power systems to pour out condensate water and keep steam inside.
