Study of Three Measures for Energy Efficiency of Fossil Fueled Furnaces and Boilers

摘要

The effectiveness of three measures of energy efficiency for furnaces has been demonstrated by comparison of the results for predicted energy saving against the cost savings predicted by the calculated total annual cost of operation using DOE test procedures. Two of the efficiency measures currently prescribed by DOE - the Annual Fuel Utilization Efficiency (AFUE) and the DOE Energy Factor (EF) are compared with an industry proposed energy factor - Seasonal Energy Utilization Factor (SEUF).
