Paper Mill Boiler. Boiler is the heart of paper mill production, the boiler used in paper mill usually is steam boilers. The role of these boilers is to produce high-temperature steam through the conversion of energy by the use of coal or other fuels, then the steam is transported to the production workshop to achieve the process purposes of cooking, drying and so on.
Energy is widely used for processes such as running motors and fans, providing compressed air, processing pulp, and drying paper. Steam is a significant utility used in pulp and paper facilities, nationally estimated to be approximately 43% of the total energy demand. Recovery of pretreatment steam during pulping and steam for drying is paramount for reusing energy.

The use of Kraft recovery boilers spread fast as functioning chemical recovery gave Kraft pulping an economic edge over sulfite pulping. The first recovery boilers had horizontal evaporator surfaces, followed by superheaters and more evaporation surfaces. These boilers resembled the state-of-the-art boilers of some 30 years earlier.
Bark boilers are primarily used in pulp and paper mills to produce process steam for paper production. These boilers are especially efficient in the production of pulp and paper, as bark is a waste by-product of previous processes involved in paper making.
The typical solvent used in the chemical cleaning of paper mill boilers is hydrochloric acid based. The prevalent use of this solvent is due to its relatively low cost and the ease of disposal of the waste solvent. The waste solvent is usually placed into a mill's process sewer after neutralization.
