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 or in making electricity, much as in a conventional steam power plant.The invention of the recovery boiler by G.H. Tomlinson
Indirect liquor heating allows recovery of the clean steam condensate. The absence of direct steam injection eliminates the risk of diluting the black liquor below the safe firing concentration Lundberg heating systems utilize liquor circulation to maintain velocity within the heater at …
2 Burning Black Liquor Takes place in the furnace section Requires black liquor and air to be intermixed Black liquor sprays Forced air system Self-sustained combustion is normal Use auxiliary fuel for start-up, shut-down, and to assist marginal combustion Combustion gas flow driven by induced draft (ID) fan Furnace Section Basically a rectangular box with openings
Designed for severe service liquor heating. Mead Paper in Kingsport, Tennessee, USA, needed to eliminate severe vibration and hammering caused by an existing black liquor heater on gun loop to the recovery boiler. The previously installed direct contact steam heater …
Black Liquor Recovery Boiler Optimization Objectives. Increase BLS Throughput The Recovery Optimization System developed by AAI utilizes the latest concepts in control strategy for Recovery Boiler Processes using the tools available in modern computer based control systems and instrumentation typical of a Recovery Boiler. As opposed to
Concentrated black liquor has high viscosity, which can cause significant problems with plugging of equipment. ANDRITZ has developed a simple yet effective treatment technology for black liquor that permanently reduces the viscosity of high dry solids liquors so that they can be efficiently burned in the chemical recovery boiler.
Black Liquor Recovery Boiler Advisory Committee. The BLRBAC is a “Trade Association” that exists for the purpose of s haring knowledge and generating and maintaining guidelines to help facilitate the safe, reliable operation of Black Liquor Recovery Boilers.. Learn more

Brand: Lundberg In thu early 1900’s, 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 1930’s to 1950’s 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
In January 1962, the Black Liquor Recovery Boiler Advisory Committee was formed by representatives of the pulp and paper industry, manufacturers of black liquor recovery boilers and insurance companies providing coverage on black liquor recovery boilers. The purpose of the committee was stated as follows:
