按照最好的生产经验操作的一般的缝隙式锻造加热炉,实际上能传给受热金属的热量还不到燃料燃烧产生热量的12％。在这类高温工作过程中唯一最大的改进就是减少加热炉排烟的能量损失。因为锻造加热炉的烟气通常为2500°F(1370℃),使用陶瓷管式换热器是有利的。陶瓷管式换热器(商品名称Cerhx)由装在绝热的钢架内的陶瓷管子组成。这种管式换热器接受温度高至2800°F(1540℃)
A typical slotted forge furnace operating according to the best production experience actually emits less than 12% of the heat generated by the combustion of the fuel to the heated metal. The only major improvement in this type of high temperature operation is the reduction of energy losses in the furnace exhaust. Because forged furnace fumes are typically 2500 ° F (1370 ° C), the use of ceramic tube heat exchangers is advantageous. Ceramic tube heat exchangers (trade name Cerhx) consist of ceramic tubes housed in insulated steel frames. This tubular heat exchanger accepts temperatures up to 2800 ° F (1540 ° C)
