  • 4-1 Recovery Boiler Equipment and Operation

    The recovery boiler is the most essential and most expensive part of the kraft recovery process. This is where the organic matter dissolved during pulping is destroyed and its energy value recovered. This is where sulfide is formed and the inorganic chemicals are recovered for reuse. The recovery boiler is an integral part of the steamLearn More

    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.Learn More

  • Kraft Process - an overview | ScienceDirect Topics

    The Kraft process relies heavily on lignin itself as fuel to operate the relatively expensive chemical recovery boiler system. Consequently, it is unlikely for the lignin produced from the Kraft process to be largely used in commercial markets or in biorefinery operations for the production of high-value chemicals ( PNNL, 2007 ).Learn More

  • waste heat recovery boiler Agent wikipedia

    Recovery boiler is the part of Kraft process of pulping where chemicals for white liquor are recovered and reformed from black liquor, which contains lignin from previously processed wood. The black liquor is burned, generating heat, which is usually used in the process of making electricity, much as in a conventional steam power plant.Learn More

  • 4-4 Recovery Boiler Chemical Principles

    In an ideal recovery boiler process, all the diverse sulphur and sodium compounds would be transformed to sodium sulphide (Na2S) and sodium carbonate (Na2CO3) and be contained in the smelt on the furnace bottom. In a real recovery boiler, however, the process is more complicated. Figure shows an example ofLearn More

    process. In modern mills, oxygen is normally used in the first stage of bleaching. The trend is to avoid the use of any kind of chlorine chemicals and employ "total chlorine-free" (TCF) bleaching. TCF processes allow the bleaching effluents to be fed to the recovery boiler for steam genera-tion; the steam is then used to generate electric-Learn More
