Paper mill boiler typically use coal boiler and biomass boiler.
steam boiler system are the core thermal equipment in paper mills, and steam is used throughout the entire process of pulp and paper production.
1. Pulping section for steam boiler system
In chemical pulping, steam boiler system provide high-temperature and high-pressure steam to the digester to decompose plant lignin and achieve fiber separation,
In mechanical pulping, steam boiler system can be used for preheating and softening raw materials.
2. Papermaking section for paper mill boiler
Coal boiler provides steam for pressing and drying sections of paper machine, and evaporates the moisture in the paper web by heating the dryer
Coal boiler provides steam for preheating and insulation in the paper forming area to improve the uniformity of paper forming.

Feature of steam boiler system
1.Paper mill boiler often uses horizontal water fire tube coal boiler or circulating fluidized bed coal boiler.
water fire tube coal boiler having a thermal efficiency of 60% -80%;circulating fluidized bed coal boiler can be equipped with desulfurization and denitrification devices, which is more environmentally friendly.
2.Steam boiler system pressure is usually 1.25-3.82MPa, temperature is 200-450 ℃
