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.
Benefits of our PR boiler design includes:
Our design features include:
A chemical and heat recovery boiler for the pulp and paper industry; concentrated black liquor and combustion air are introduced into the furnace where heat is recovered as steam for electricity generation and process heating, and the inorganic portion of the black liquor is recovered as sodium compounds.
