Annotation: Boiler making is a strategic industry. Its development allows the state to solve the issue of economical use of fuel in all industries. Reliability and efficiency of the heat generating equipment, its operation without harm to the environment are key indicators of effective energy supply of the country. The main trend in the world progress in the municipal power system is to reduce the cost of fuel for generation of heat by increasing the coefficient of performance (COP) of boilers. One way to improve efficiency is to install the tubes turbulators in convective package. The aim is to determine the effect of the turbulator on the intensity of heat transfer in the convective part of the fire-tube heat source of domestic production. The paper presents the experimental data of such a boiler, as well as theoretical studies to determine the characteristics that influence the heat transfer, depending on the degree of overlap of the channel cross section tubes with a turbulator in the form of a broken belt.
Keywords: heat transfer, convective tube, turbulator, the degree of overlap, temperature, turbulent viscosity, the heat transfer coefficient.
