| Popis: | Publisher Summary This chapter presents an analysis of the efficiencies and inefficiencies of a system, which can be used to identify where the greatest opportunity for gains can be derived. It can also be used to benchmark the performance of one system against another. The thermal efficiency of any furnace system is defined as the useful energy derived from the system relative to the energy input. However, it is not necessary to measure the energy that is lost through the walls of the furnace, etc. to calculate the efficiency. It is only necessary to know the useful energy out, which is usually relatively easy to determine, as it will be directly related to the production rate. The efficiency of a furnace system depends on each step by which the energy is transferred from the chemical fuel energy and the electrical energy to the process energy contained in the end product. The total efficiency is dependent on the efficiency of each operation in the process, such as pump, preheater, furnace, and cooler. Examination of furnace performance data can help to usefully identify the relative contributions of thermal quantities. If the production rate is plotted against thermal input then, allowing for a reasonable degree of scatter owing to other influences, a straight line relationship is usually observed. |
