Abstract :

Background and Objective: Currently, there are many environmental challenges and crises such as air pollution and its unpleasant effects on human, plants, animals and even man-made buildings and structures. Use of fossil fuels to supply the energy requirements for different activities and spaces is the main reason for occurrence of air pollution. Usually the share of residential centers is not considered. In particular, the major trend in residential centers is using central boiler houses, which further highlights the importance of air pollution and its control in these pollutant stationary sources. Method: In this process, boiler house is inspected by spatial arrangement, technical operation, efficiency and combustion products. Afterward, by tuning the performance of the burner, detection of probability defects and proposing the solutions, that process is optimized as much as possible. Findings: The result of this project shows that the performance of the boiler house is undesirable. The reasons for this situation are: non-compliance of standards in boiler house building, improper arrangement of equipment and its undesirable operation, lack of timely service, unadjusted burners and improper chimney draft. These problems cause excessive and incomplete consumption and consequently lead to air pollution. Considering the importance of air pollution, especially in metropolitan and industrial cities, and also limited energy sources, technical inspection of boiler houses can be a way to access three main and effective objectives: optimization of energy consumption, reduction of air pollution and residents safety in buildings.
