COMPARISON OF ACCOUNT PROGRAMS IN A STAINLESS STEEL CHIMNEY APPLICATION

Abstract

Exhaust gases produced by heat sources must be discharged into the atmosphere in the most reliable way without harming human health. This is possible with the chimneys attached to the heat source. There are some standards for positioning the chimneys according to the existing structures, determining the minimum height and calculating the chimney section. The correct sizing of the chimneys also directly affects the performance of the heat source. The large selection of the chimney diameter at a fixed height causes the hot air inside the heat source to be thrown to the atmosphere more than necessary, it means incomplete combustion formation and also excess cost. Small selection of the chimney diameter affects the combustion performance of the device and causes loss of efficiency. For this, the ideal chimney diameter should be chosen considering the existing conditions. There are many calculation programs where chimney diameter calculation can be checked in computer. Chimney diameter calculation can be checked quickly by entering different diameter range with the user's comments. When it is desired to use air exhauster to provide additional flue draught contribution to the system, it is necessary to select the restricted devices specified in the program.Therefore, calculations cannot be made or the missing diameter is calculated. This creates difficulties for its users, chimney controllers, and is often miscalculated. In order to overcome the difficulties mentioned in this study, a chimney diameter calculation is designed in which the air exhauster features can be entered manually in Excel format. Without the air exhauster of a project application to be made with both Excel account both accounts with Turkey and several European countries used Kesar Aladin chimney calculation program is made. The results were compared and comments were made on the correctness of the account. In addition, stainless steel chimney calculation and application of a natural gas fired lahmacun furnace were made by adding a air exhauster.
