A Major Milestone Acheived at Snetterton Biomass Power Plant

The first steam blowing was successfully conducted at Snetterton Biomass Energy Plant, where ACP Concrete recently completed installation of the precast walls. In layman's terms steam blowing is cleaning out the boiler prior to commissioning and is a major milestone on the way to the anticipated full operation of the 44.2KW biomass energy plant in 2017.

ACP Concrete recently completed installation of the precast walls at Snetterton Biomass Energy Plant.  Since starting on site in September 2015 ACP have manufactured and installed 2700m² of 180mm thick firewall panels to the Boiler House, Turbine Hall and Fuel Store. The 44.2KW biomass energy plant will be fuelled annually by 250,000 tonnes of baled straw supplied by local farmers, as well as woodchips.  The main part of the power plant is a boiler from BWE which is said to be the world's largest water-cooled vibrating grate straw-fired boiler.  The boiler installation date was critical and the project was hampered by high winds which led to a delay erecting the steel frame. However  the challenge  brought out the best in the production and fitting teams who managed to complete each phase on time working at heights of 24m and coordinating installation of the prestressed concrete cladding with the steel frame erection team. Flexibility was key to success.

The final phase was the slag store installed in September this year. The innovative construction was designed by Ramboll and manufactured and installed by ACP. The giant 3D concrete jigsaw had no supporting steel frame and required a complex system of props during construction. It demanded precision manufacture to ensure that the pieces fitted together and the whole structure was brought together with the installation of the roof and the screed topping. The installation took 20 days from start to finish to the satisfaction of all involved.  It is anticipated that the power plant will be operational in 2017.
