The preheating method includes heat-pipe exchanger, tubularheatexchanger, plate heat exchanger, heat medium exchanger and regenerative hot stove.
预热法包括用热管换热器、管式换热器、板式换热器、热媒式换热器和蓄热式热风炉。

Heat exchange efficiency varies greatly with different structures of heat exchangers. Partial modification of the tubularheatexchanger can raise its heat exchange efficiency.
换热器的结构型式不同，其换热效率差别很大。对管壳式换热器结构做出局部改动，可以提高换热效率。

Then SINOPEC engineering incorporation drew up the engineering drawing a-gain in 2002, and it was named as 《U shape tubularheatexchanger series engineering drawing》.
