The first CFB steam generator built in Russia by Krasny Kotelshchik and Amec Foster Wheeler.

February 26, 2016: The erection of the first CFB steam generator in Russia has been completed in the Power Unit #9 of Novocherkassk State District Power Station. It is also the second CFB (circulating fluidized bed) steam generator in the world, which utilizes advanced supercritical once-through (OTU) steam technology. The equipment was jointly designed, manufactured and delivered by Taganrog Krasny Kotelshchik boiler factory (incorporated into OJSC Power Machines) and Amec Foster Wheeler (United Kingdom). The commissioning works are still in progress.

Despite a higher cost for a unit of boiler equipment of such type, OTU-CFB technology offers many advantages. The CFB steam generator improves overall power plant efficiency, resulting in producing about 5-10% more electricity from the same amount of fuel consumed as compared to a conventional subcritical steam power plant. Furthermore, this fuel savings translates into approximately the same amount of reduction for the plant's air and ash emissions helping to reduce the plant's environmental impact. The specific limit value of solids will not exceed 50 mg/nm3 with the RF norm equaling to 150 mg/nm3. CFB boilers are also cost-effective due to a higher efficiency when firing low-grade fuel as the unburnt fuel particles return to combustion chamber and are mixed with a new portion of fuel. It is worth to say that CFB technology allows firing high ash content low-grade fuels.

Thus, commissioning the new 330 MW Power Unit #9 will improve performance of Novocherkassk SDPS (The Novocherkasskaya GRES), providing a new reference for Taganrog Krasny Kotelshchik boiler factory. It is to note that, eight 300 MW boiler units operated at Novocherkassk facility were also manufactured in Taganrog.
