This study showed that the conditions of operation of the boiler were often not sui table for this type of boiler and For this type of fuel used especially the excess air ratio. It was higher than the required values several times, which leads to a large waste of energy spent and adversely affect the efficiency of the boiler . Therefore, the conditions of running the boiler have been modified. Basically, an increase in the air,which led to an improvement in its performance through Basically, air increase factor,which led to an improvement in its performance through:•Improved combustion process after modification And reduced emissions of non-burnt gases by 66.66% for CO and 45.8% for H2•Increasing yield from 87.4% to 90%, an increase of 3.1%, which givesus a fuel saving an average 62 tons of fuel annually•Increasing Sulfur dioxide (SO2) slightly by 11.6% due to conversion part of SO2 to SO3 before modification•Increasing nitrogen monoxide (NO) slightly by 36.5% due to cooling before modificationWerecommend adjusting the conditions of running the boiler Mainly an air increase factor according to real operating conditions and and generalization of results on other four boilersThe study of fireside deposits in heating boilers that has been conductedshowed that the deposits are placed unevenly on the various heating surfaces of the boiler. The thickness of the deposit layer was between 2 and 5mm, so the percentage of wasted fuel was about 5-10%, which decreased the boiler efficiency. The PH levels ofthe deposit samples were between 2.25 and 3, while the sulfur content was averagely 0.22mg/g. Which leads to the corrosion of the metal surfaces in the boiler, caused by the contact with an acidic substance containing a high level of sulfur.
