TDF as Fuel in Waste Wood Boilers at Pulp and Paper Mills
Aug 18, 2019 · Tires, as mentioned earlier, generate 15,000 Btu's per pound. Bark is the most common component of waste wood in the pulp and paper industry.1. Many mills burn this wood waste in boilers to obtain heat energy for process steam, and to alleviate possible solid waste disposal problems. These waste wood boilers are known as "hog-fuel" boilers.
