Numerical Study On Atomization And Combustion Of Burner Used In Offshore Drilling Platform

Off-shore plates are bases for ocean drilling,Burning arm also known as the flare booms,it is a fundamental instrument for off shore drilling and petroleum production.The flare booms has three main functions:stable production,safety and environment protection.The requirement of safety and environmental protection and reliability of offshore oil drilling platform is very high.Due to the domestic research on combustion arm system started late.The important equipment,including burner,need to be imported from abroad.The purpose of this paper is to simulate the internal flow field,the atomization and combustion of petroleum,and to provide reference for the research and structure optimization of the burner.1.In this paper,the production of well test production and the processing mode of the test fluid,the combustion process flow of crude oil in the test production and the related important equipment are introduced.2.The mathematical model of Computational Fluid Dynamics and the mathematical model of turbulent flow,two-phase flow,atomization and combustion are introduced in this paper.3.Three dimensional modeling and grid division of the internal flow field of the burner are carried out,and the independence of the internal flow field is analyzed.The influence of compressed air flow and fuel specific gravity on the flow field in the combustor was obtained by controlling variable method.4.Simulation of spray flow field of oil,in order to determine the influence of compressed air flow on the particle size and flow field distribution of the oil atomization.5.According to the API 521 oil and gas pressure relief system guide to the torch length and the diameter of the theoretical calculation.
