Dual Burner RLS28 Riello

Fuel setting: Complete combustion of fuel is the result of fine-tuning the ratio of fuel to air.The more accurately this ratio is set, the higher the combustion efficiency, resulting in less fuel. In small burners, the combustion of the burner needs to be regulated by a manual damper, but in large burners, this adjustment is provided by the automatic damper of the air required for combustion.However, due to the fact that the air temperature of the boiler house and its humidity varies throughout the year, in large burners, the air damper must be re-adjusted in each season.Today, modern burners are equipped with an intelligent PLC control system that automatically adjusts the ratio of fuel to air throughout the day and all seasons.Due to the incomplete efficiency of fuel combustion in burners and taking into account some heat losses, when choosing a burner, we consider the capacity of the burner to be about 20% higher than the capacity of the boiler.For every 300 meters of increase in the height of the door surface or due to the decrease in air concentration, the fuel combustion efficiency of all types of burners is reduced by about 4%.The calorific value of each cubic meter of natural gas is approximately equal to K.cal 9200.The calorific value of each liter of diesel is approximately equal to K.cal 8500.The calorific value per kilogram of diesel is approximately equal to 10,500 K.cal.
