Process Recovery (PR) Boilers
B&W's single-drum recovery boiler, now the standard in the pulp and paper industry, provides high availability with safe operation and low maintenance. We have been at the forefront of technologies which improve boiler and cycle efficiency, such as firing higher solids concentration liquors, using low pressure steam to heat combustion air, and feedwater heating.
3. Thermodynamic analyses of proposed waste heat recovery system
The higher feedwater inlet temperature reduces the temperature drop of flue gas in LPE, which leads to the decrease of recovery heat. This paper proposes a waste heat recovery system (WHRS) which improves waste heat utilization efficiency without reducing recovery rate by converting recovery heat.
