Chemical Recovery Boilers in Pulp and Paper Plants - Part 1

In thu early 1900s, the chemical recovery function was achieved in smelters or roasters wherein black liquor was burnt to recover inorganic chemicals and the heat energy was either wasted or partially recovered. The 1930s to 1950s saw the introduction of tangent tube water wall bi-drum boilers which put the emphasis on chemical recovery and also on heat recovery to produce steam for
