Paper industry has always been key industry for energy saving, emission reduction and reducing consumption in our country. However, modern paper machine has a great advantage of saving energy and lowering consumption. The saving energy and lowering consumption in the modern paper machine with advanced control and higher speed technologies have been accomplished by way of increasing the overall efficiency, in which the structure of unit, key technology and the papermaking efficiency were improved. The key technology of each unit in modern paper machine and its effect on saving energy and lowering consumption were also introduced. The speed and width were presented, and some suitable suggestions for developing and producing the modern paper machine were provided according to the technology problems still existed and actual situation in China.
