Peculiarities of the Generation of the Temperature Field in Stabilizer Burners at the Microdiffusion Popping of Gas

The efficiency of the thermodynamic cycle of the thermoenergetic plant is defined to a great extent by burner characteristics. This scientific paper gives consideration to the formation processes of the temperature field of combustion products in the combustion chamber at microdiffusion popping of gas behind flat collectors- stabilizers with the injection of fuel into the recirculation zone that is distributed along the stabilizer length. It was shown that the profile of the gas temperature along the stabilizer height required by burner operation conditions can be provided by an appropriate change of local fuel consumption. It was noted that due to a high gradient of velocities and temperatures in the trace cross-section behind the stabilizer the mixing process of combustion products and the air in the inter-stabilizer space is characterized by a high intensity. For the studied options of burners at the stabilizer width of Bst = 30 mm and 45 mm and jam coefficients Kf = 0,6 to 0,8 the length of the chamber on which the chamber section rectification of temperature field occurs is equal to 10–15 calibers of the stabilizer and depends on the lattice density and excess air factor.
