Exhaust gas heat recovery boiler AV-6N AV-6N is a robust, highly efficient water tube boiler, designed to improve the plant’s total efficiency. With AV-6N, exhaust waste heat can be recovered from various sources such as diesel or gas engines to generate steam and/or heat water. It is flexible and easy to install - even in existing facilities. The standard AV-6N exhaust gas boiler for steam application has a natural circulation design offering several operational advantages compared to traditional forced circulation. EMD00280EN 1107 AV-6N heat recovery boiler improves overall efficiency AV-6N is the optimum solution for high-performance heat recovery systems. Designed with extended heating surface, AV-6N is compact and cost-effective. The possibility of cleaning during operation minimises the need for engine shutdowns and increases the overall plant availability. Unique boiler construction A unique supporting arrangement without endplates - enhanced by computerised analyses - ensures a vibration and thermal stress-free boiler structure sustaining even the most demanding operational conditions of engine-based heat recovery applications. Reliable natural circulation As a standard for steam applications, Alfa Laval Aalborg offers reliable natural circulation solutions without the need of circulation pumps providing the following advantages: • • • • • • • Reliability Minimised risk of sootfires Less power consumption Cost effectiveness Fast site installation Reduced foundation work and minimized piping and cabling Small footprint Traditional forced circulation boilers are also available. Easy to clean The tube arrangement of the AV-6N heating surface ensures easy maintenance and service. AV-6N boilers can be cleaned during operation reducing the need for engine shut-down. In addition to standard high-efficient steam soot blowers, an air-type can also be applied.
