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

Boiler Filling Operation for Hydrostatic testing. In case of welded safety valves, remove the hydro test plug and re-install the normal safety valve seat, after de-pressurizing and draining the boiler. In case of flanged safety valves, remove the blind flange and refit the valves. Re-install the instruments that have been sealed off for the test.

The gases from the combustion of the black liquor leave the fireside and carry the heat to the heat transfer section of the boiler. The recovered chemicals flow out of the bottom of the boiler fireside and are converted into green liquor. The module describes the operation and components of the fireside of the kraft recovery boiler.

The idea is to find the tube in the boiler with the most deposit in a high-heat area. You cannot use a tube that has failed, because some or all of the deposit will have been removed by the failure.

Get a QuoteA black liquor recovery boiler has two main functions. On one hand, it generates steam from the heat energy liberated upon combustion of the organic constituents of black liquor burned in the boiler, whereby the recovery boiler serves as a steam boiler. On the other hand, the chemicals from pulp digesting - sulphur and sodium - are recovered
