The invention of the recovery boiler, by G.H. Tomlinson in the early 1930s, allowed kraft mills to recycle almost all of their pulping chemicals. This, along with the ability of the kraft process to accept a wider variety of types of wood and to produce stronger fibres, made the kraft process the dominant pulping process, starting in the 1940s.

Construction, Working, Operation and Maintenance of

Electrostatic precipitators (ESP) are used in most pulp mills to remove particulate from recovery boilers, power boilers, and lime kilns. As environmental regulations have increasingly become stringent in recent years, maintaining a high ESP performance is of vital importance in mill operation. This paper discusses results of a literature review of the ESP technology used in industrial combustion units including recovery boilers, …

To replace its recovery boiler's abandoned oil burners, B&W supplied a mill with three natural gas LM2100 load burners and Class 1 FPS gas lighters. The burners raise boiler pressure and supplement steam generation during the recovery process, eliminating the need for the mill's power boiler. Wet Electrostatic Precipitators

WO2011002354A1 - Process for improved leaching of

The invention relates to a process for purifying recovery boiler electrostatic precipitator ash (via 19) from chlorides (Cl) and potassium (K), and recover useful pulping chemicals such sodium sulphate (Na 2 SO 4 ). The inventive process uses two centrifugal separation stages (2a, 2b) in series with a leaching stage (1 a and 1 b) ahead of each centrifugal stage.

ESP for a recovery boiler - Valmet ECP Oy

ESP for a recovery boiler. The recovery boilers of pulp mills typically have electrostatic precipitators for cleaning flue gases that were installed when the boiler was built. These precipitators have often worked for as long as several decades. The old precipitator technology might well have been left behind the current standards during that time.
