Several events can cause unplanned shutdowns of recovery boilers.One of the most extreme causes is the cracking of boiler tubes. When cracks in the boiler tubes extend deep enough to allow water and steam to leak into the recovered molten pulping chemicals (smelt) on the floor of the boiler, a large explosion can occur. Cracked tubes can take days to weeks to repair and result in significantBuckman's Recovery Boiler Advisor leak detection monitoring system gives boiler operators updated information four times a minute. The Recovery Boiler Advisor (RBA) is a comprehensive leak detection system that helps operators decide on the need to perform an
Recovery boiler 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 challenge. The chemical recovery boiler is an essential part of the pulp production process as it recovers and regenerates cooking liquors. The challenge is to select a recovery boiler that not only recovers chemicals and generates power efficiently, but also does this in a safe, reliable, and environmentally sound process.
A survey was made of the 162 primary air ports in the composite tube waterwall of a 3 onehalf year old 1450 psig Babcock and Wilcox recovery boiler.One successful example is the waste heat recovery boiler, which can be situated above heatgenerating equipment to generate steam that can drive electricityproducing generators. There are many ways in which waste heat can be lost, including flue gases, heat loss from pipes, boiler exhaust and warm air vented from heated rooms.
