In order to improve identification of new products, we study the energy efficiency test of utility boilers. According to related protocols and test method of the current boiler energy efficiency, we build up the model of boiler thermal efficiency test in direct and indirect procedure. During the procedure, we analysis some key issues such as the blended fuel problem and the desulfurizer’s effect on energy efficiency. On this basis, we develop the Utility Boiler Thermal Efficiency Test System, which is used in boiler industry and achieves the intended purpose.

For ten different kitchen ranges, forty-six different cooks prepared a standard 21 meal menu while the energy used by each cook was measured. The energy efficiency of each range was then determined and the ranges were rank-ordered in two ways—on the basis of measured range efficiency and energy actually used by cooks. In general, the higher the measured efficiency the lower the total energy use. This was an important result because it meant that the range efficiency test method to be required by Department of Energy (formerly Federal Energy Administration) regulations was a fair method for manufacturers to use. In addition to that result, large differences were noted in energy consumption by different cooks on the same range. The implications of those differences, and the need for further research about them will be discussed.

Recognition of the energy savings potential in motor driven systems has led to the development of energy efficiency testing and classification standards for motors and end-use equipment (e.g., pumps and fans) and the implementation of minimum energy performance regulations targeting them worldwide. However, these standards and regulations have been limited to components, disregarding the interaction between them. The energy savings achievable by addressing and improving the entire system are potentially much higher in relation to those achievable when considering individual components. Recently, an effort to develop standards in this regard was carried out by standardization bodies (IEC and ISO) leading to the publication of the IEC61800-9 Power Drive System standard series. The paper, in its first part, describes recent evolutions in electric motor energy-efficiency standards and in the implementation of related regulations worldwide. In the second part of the paper, using the latest energy efficiency test and classification standards, a comparative analysis of different energy-efficient motor technologies is presented. Using results from laboratory tests combined with data provided by manufacturers, different power drive systems are compared considering different operating points in two typical pumping systems. Estimated economic savings from a total cost of ownership perspective are presented.
