Improving the sprancity of the ORC boiler

Today I’d like to report on an ORC boiler efficiency improvement project we completed for a large paper industry client. The customer operates the OR-16 boiler to supply steam to its technology. Efficiency measurements performed (based on laboratory tests of fuel and slag and measurements of boiler operating conditions) showed an efficiency of less than 70%. The boiler’s blast box was upgraded and then the efficiency measurements were re-measured using the same methodology used as standard in large utility thermal power plants. Realized measurements showed an efficiency of just over 90%. Investment outlays closed in the amount of about PLN 600 thousand, while annual savings through reduced fuel consumption amount to more than PLN 1,300,000 per year. In addition, funds were raised from awarded energy efficiency certificates in excess of 1,500 toe. Importantly – annual carbon dioxide emissions fell by 7,126.41 _MgCO2/year
