Abstract
The results of the experimental determination of the heat losses in fixed supports of low, medium and high pressure steam pipelines in firm Lukoil Neftochim Burgas have been summarized. In the conditions of a three-factor experiment, the exponents of the regression equation have been determined. For determination of convective heat exchange coefficient (α), the Newton-Rihmann equation has been used as a boundary condition of a third kind of heat transfer equation. Experimentally obtained α dependency has been shown as a function of the dimensionless temperature and the velocity and angle of the airflow of support. The results obtained shall be considered as part of the effort to structure user-friendly software for heat losses determination of steam pipelines and their components by means of thermal imaging equipment.
