Recovery boiler - Wikipedia

2019-5-10 · 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
