Abstract


This search is evidence that development plans and environmental conservation go in one direction, where we can decrease environmental pollution with economic benefits simultaneously. By monitoring emissions from four boilers stacks (from petrochemical and food sectors) which working by natural gas. Changes in excess air were conducted to increase combustion efficiency means fuel savings, and decrease pollutant concentration, where there is a relationship between cost, combustion, stack heat loss, fuel-saving, and environment. Combustion efficiency and emitted pollutants from the stacks were measured before and after maintenance, where mixed-air with fuel is changed. In boiler 1 of petrochemical sector, carbon monoxide changed from 2222 to 21 mg/m3. In boiler 2, CO changed from 4695.3 to 5.5 mg/m3. The efficiency of boiler 1 and 2 improved from 75.5% to 92.1%, and from 71.5 to 93.1% respectively. In boiler 1 of food sector CO changed from 2200 to 45 mg/m3. In boiler 2, CO changed from 1900 to 59 mg/m3. The efficiency of boiler1 and 2 improved from 69.8% to 91.4%, and from 76.5% to 91.1% respectively. The cost reduction per year was 8469.1$ and 11692.8$ in the petrochemical sector, while it was 11624.4$ and 12168.2$ in the food sector. Where the cost of maintenance for each boiler was 100,000$, the payback time is 5.11 years for boiler 1 in the petrochemical sector and 3.99 years for boiler 2, while the payback time is 3.86 years for boiler 1 in the food sector and 5.68 years for boiler 2.
