As a result of the examination made with a thermal camera in an industrial baking oven, 20% of the energy of the fuel entering the oven was determined.
It was determined that it escaped from surfaces. By renewing the insulation of only the side surfaces of the furnace, the escaping energy can be reduced.
It was calculated that the rate could be reduced by 52%. Oven dimensions 5x5x40 m, hourly natural gas consumption 200 Sm³ natural gas calorific value 8,250 kcal/Nm³ and the annual operating time of the business is 7,000 hours. m² of insulation including all costs.The application price is 1,800 TL and will last 15 days. The oven will not operate during insulation application and the daily profit of the oven amount is 100,000 TL, natural gas price is 9.3334 TL/Sm³ and natural gas prices are increased by 10% every 6 months.Annual discount rate Since it is 23%, calculate the simple and adjusted payback period.
