THERMAL BOILERS FOR CIVIL USE: STUDY ON ORDINARY MAINTENANCE

The aim of the present research was to study the role played by the ordinary maintenance of thermal boilers for civil use on the reduction of emissions into the atmosphere. For this purpose, the flues gas emitted by a sample of 20 boilers, different by brand name and by date of installation, were compared before and after ordinary maintenance.The flues gas of the boilers were measured by the particle analyzer (Seitron). The parameters measured were different such as: flue gas temperature, carbon monoxide (CO), carbon dioxide (CO2). The set of data obtained shows that an adequate routine maintenance of civil heating systems is of fundamental importance and it can guarantee a reduction in emissions. Boilers with the same year of installation and the same commercial brand showed different emissions, highlighting that a young age, a particular commercial brand of a boiler are not enough to guarantee a lower environmental impact but a regular maintenance checks and an appropriate use are always necessary
