ERK introduces compact fire tube heat recovery boiler range for marine and industrial applications

07. May 2016

ERK has a long track record of marine boilers with more than 600 references for hot water, thermal oil and steam boiler. These references include directly fired and heat recovery boilers on tankers, platforms, FPSO’s etc.

Until now, all our marine projects involved natural or forced circulation water tube boilers but with ERK’s proprietary ERK Tube technology, we are now also offering licenses for fire tube boilers. The ERK Tube technology enables weight and volume reductions of up to 40%. The case study on the right shows three different marine boilers with thermodynamically identical parameters , with a plain tube example at the top and two ERK Tube versions below. The smaller ERK Tube units lower the direct boiler cost and associated costs, such as transport, number and size of deck openings, and installation cost.

ERK Tubes are already being used in stationary fire tube boilers and marine heat exchangers. Total ERK Tube marine references to date exceed 20 units with forward contracts until 2018. The stronger focus on energy efficiency in the marine industry is likely to lead to a growing marine boiler market. ERK is now uniquely positioned to provide designs for standard and tailor-made projects with natural and forced circulation water tube boilers as well as compact fire tube boilers.
