Abstract
In every boiler plant, including industrial boiler plants of thermal capacity above 2 MW, substantial heat gains are generated during the work of combustion units. As a result, the indoor air temperature raises in the room, which affects thermal comfort of workers operating such technological installations. Therefore, heat removal requires an effective mechanical ventilation system. A numerical analysis of the selected air parameters in a room equipped with combustion devices was undertaken using computational fluid dynamic (CFD) simulations in the DesignBuilder software. This was done for a combustion plant in the “Installation of Thermal Treatment of Sewage Sludge” building, located in the “Group Sewage Treatment Plant” complex of Lodz, Poland. The numerical analysis was based on experimental measurements and the results concerning the personnel work area were compared to the guidelines of the ISO international standard 7730:2005.
