Influence of lime adding method on scaling process in Bayer preheating process of diasporic bauxite slurry;

The buried hot oil pipeline preheating process is a process of heat and instability.

After the air preheater system of hydrogenated reaction furnace changes into heat tube preheater,the heat efficiency of furnace increases about 3%.

Scale formation reason and disposal for air preheater of heating furnace;

Design load-carrying for preheater tower of Saudi Arabia 5000 t/d production line;

Basing on the basic principle of momentum transfer, heat transfer, mass transfer, and reaction, this paper establishes the mathematical models about the mass balance, gas balance, and heat balance during the pre-heating process of 4 kinds of whirlwind pre-heater systems which are with different series and different stage numbers.

The effects of pre-heater and pre-polymerization reactor temperatures, reflux rate and material level on product quality were studied during caprolactam pre-polymerization and post-polymerization.

The paper describes the development of the pre-heater of hot-blast stove for blast furnace, and the technical advancements of the pre-heater in terms of material, heat exchanger type as well as heat transfer medium.
