Abstract

Steam transportation systems typically include large steam lines with a large variety and number of transition elements such as valves, flanges, orifice plates, etc., installed along with them. When evaluating the efficiency of the transportation process through a steam pipeline and determining the main causes that impact energy loss, it has been found that the procedure for quantifying energy losses in steam pipeline networks relies on simplifications that arise from the complexity of the conditions under which they operate. This paper presents a calculation procedure to determine heat losses in the pipes of a steam transportation network, which is based on geometric information of the line and the state of its thermal insulation, as well as the conditions under which the network operates. The results obtained were compared to calculations of surface temperature and heat loss in a steam pipeline with different insulation conditions. The proposed methodology has the advantage of being simple and easy to implement on a personal computer with Microsoft Excel without requiring a high investment, unlike commercial software that has a high cost and requires computer equipment with more specific features.
