Chemicals used in paper mill production such as sodium hydroxide, sodium sulfate, sodium carbonate, etc. need to be heated by steam. In addition, steam is required for processing and forming paper, black pulp concentration, and so on. The boiler is the heart of the paper mill’s production. The main driving force is indispensable for every paper mill. The function of these steam boilers is to use coal or other fuels to generate high-temperature steam by converting energy sources, and then transport the steam to various production workshops to achieve a variety of process purposes such as cooking and drying.
