Optimization of different fuel combustion conditions of multi-component thermal fluid generator
The measurement and analysis of typical combustion components of multi-component ther-mal fluid generator in heavy oil injection is the key to the evaluation of injection capacity,recovery ef-ficiency prediction,multi-cycle injection optimization.In this study,three-dimensional simulation modeling of multi-component thermal fluid generator was carried out by Fluent to simulate the distri-bution of temperature field and flow field under different working conditions of fuel combustion cham-bers.The results show that corresponding fuel nozzles for different multicomponent thermal fluid gen-erator need to be designed according to different fuel flow patterns to facilitate full combustion of fuel and improve thermal efficiency.When diesel is used as fuel,the fuel nozzle needs to be matched with the air nozzle to strengthen its atomization effect.Natural gas is preferred as fuel for multicomponent thermal fluid generators.And if fuel supply conditions are limited,the diesel in liquid phase and natu-ral gas in gas phase could substitute each other as fuel in the same multicomponent thermal fluid gen-erator.When pulverized coal is used as fuel,it is difficult to fully burn even if there is excessive O2.However,when considering cost or lack of other fuels,the fuel nozzle design can be optimized to fi-nally realize the efficient combustion of pulverized coal in the multi-component thermal fluid generator.
