Analisis Perbandingan Stoichiometric Combustion Air Secara Teoretis Dengan Aktual Pada Recovery Boiler

ABSTRACT

Recovery Boiler is an equipment in the pulp and paper industry that has two main functions, producing steam from the heat energy when burning the organic elements of black liquor and recovering the chemicals from black liquor (especially sodium elements) to be used again in the pulp cooking process. One of the main component in Recovery Boiler is the Combustion Air system which supplies air into the furnace to burn Black Liquor perfectly, control the size of the char bed, maintain the smelt reduction process, and to reduce harmful gas emissions from the Recovery Boiler such as carbon monoxide (CO), nitrogen oxide (NOx), and sulfur dioxide (SO₂). This study aims to calculate the Error Percentage between the Combustion Air Flow obtained through the calculation of the stoichiometry of the combustion reaction with the actual value obtained from the Recovery Boiler’s operational data and to identify the deviation pattern between those two values using quantitative methods by calculating the Error Percentage and using linear regression. The results obtained from this study are the average Error Percentage between Theoretical and Actual Combustion Air during 8th of March until 24th of April 2024 of 10.68%. During this period, the actual Combustion Air value tends to exceed its theoretical value when there is a decrease in Black Liquor Flow, and tends to be below its theoretical value when the Black Liquor Flow value is high. This will cause an increase in Excess Air at the Recovery Boiler when the Black Liquor Flow is decreasing.
