| Popis: | The article is devoted to the development of the design of a low-pressure injection burner equipped with a thermal divider and the study of the process of distribution of methane concentration and velocity of gas-air mixture velocity in the burner body. The Solid Works Flow Simulation software complex is used to study the process of formation of the gas-air medium in the burner body. The design of a low pressure injection burner with a conical-shaped heat spreader has been developed. Placing the divider in the burner body provides preheating of the gas-air mixture and allows to increase the speed of flame propagation. Computer simulation of the process of gas-air mixture formation in the burner body for 3 burner constructions is performed: without a divider, with a divider length of 11 mm and a divider length of 25,5 mm. As a result of modeling, it is found that the placement of the divider with a length of L = 11 mm does not affect the distribution of methane and the velocity of the gas-air mixture in the burner body and at the exit of the firing holes. Increasing the length of the divider to 25,5 mm leads to an increase in the speed of the gas-air mixture and an increase in the concentration of methane in the firing holes. Therefore, the placement of the burner housing to the heat spreader with a length of 11 mm is the best solution to improve the efficiency and stability of the combustion process. |
