“…3 (c) show that the outlet temperature changes greatly, in the process of production of gas well, the gas solid two phase fluid change pressure by the nozzle and ensure the stable pressure of natural gas production, temperature reduction is inevitable during pressure drop, because the fluid in the pipe are natural gas, the temperature of natural gas should be higher than 21 degrees to ensure the normal production. Considering solid particle impact [6][7][8][9] , Fig. 3(d) shows maximum erosion rate occurs in position where the fluid change direction in the nozzle and maximum reaches 0.0214kg.m -2 .s -1…”

Abstract. High-speed gas in wellhead throttling nozzle carry condensate water and sand, which cause serious erosion to nozzle. Erosion rate with the velocity generally show an exponential growth, the higher the gas velocity inside the nozzle, the more serious erosion. This paper mainly analyze gas fluid flow in nozzle and propose optimization project of nozzle structure. This project try to decrease fluid velocity turbulence structure and erosion under pressure drop and temperature are satisfied.

Highly efficient electric power generation from biomass/waste fuels becomes an important worldwide issue to prevent global warming. In these plants, severe high-temperature corrosion and erosion-corrosion damage occur in boiler tubes influenced by HCl, SO x gases, and chlorides as contaminants in fuels. Coating technologies become important as a countermeasure for such damage, because of the easy maintenance, cost performance, and ease of application on various materials. In severe corrosive conditions of boilers, formation of dense, homogenous, and tough coating layers, as well as protective oxide layers of corrosion-resistant materials, are important. In the last 30 years, materials and coating processes applied in shop and on site have progressed based on many field observations and the consideration of deterioration mechanisms in order to maintain long lifetimes in the plants. Furthermore, new innovative coatings are now being developed by using advanced precise control, nanotechnologies, etc. This paper introduces recent trends of advanced coating developments and applications, such as weld-overlay, cladding, thermal spray coating, and slurry coating for biomass/waste boilers. Furthermore, the evaluation results of deterioration mechanisms and lifetime of coatings, and the future issue for innovative coatings, are presented.

In this study, the solid particle erosion behavior of solutionized, articially aged (T6) and annealed aluminum alloy AA7075 has been investigated. The samples were eroded in solid particle erosion test equipment at 45• impingement angle and 75 m/s impingement velocity with 180 mesh garnet erodent particles. Afterwards, microstructures of solutionized, articially aged and annealed samples of AA7075 alloy were analyzed. In order to gure out the eect of ductility on erosion rates, the Brinell hardness of the samples was measured. The surface morphology images of the samples were taken before and after the erosion test by using scanning electron microscope (SEM). The eects of the microstructures and the hardness on the erosion behavior of the dierent heat treated specimens were examined. Finally, SEM images of the samples were deeply analyzed and the erosion mechanisms which occurred on the surfaces of the samples were discussed.
