Heat recovery from pulp processing (boiling/heating) during processing of biomass pulp in paper mills, heat is supplied from a boiler. 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. This paper gives a short overview of the picture evolving from the recent research. The recovery boiler was centrepiece to these concerns and, from the outset, sun paper was looking for the best and most efficient technology. • first successful soda mill, 1866. Product liquor solids and high solids firing most north american pulp mills fire liquor in the recovery boiler at dry solids level in the range of 68 to 75%. Generally, each paper mill is linked up with one recovery boiler and hence its availability and efficient operation are of utmost importance. History • soda pulping process patented, 1854. Longer term, there appear to be significant opportunities for increased production of Excess deposits within boiler tubes can cause failures of the tubes, which not only result in lost production, but can also place mill personnel and equipment at risk of injury and damage, particularly in the case of a chemical recovery boiler. The sodium sulfate or kraft pulping process was patented in 1884 and accounts for over 80% of all pulp produced in north america.
