Estonia: Oil Shale to Gas Sumitomo Completes Modernization of Enefit's CFB Boiler
Sumitomo SHI FW announced the successful completion of a CFB boiler technology upgrade project to increase the oil shale retort gas combustion in an existing circulating fluidized-bed (CFB) boiler at the Enefit’s Narva Power Plant in Estonia.
Espoo/Finland — As a result of the project, Enefit will be able to burn the entire volume of shale oil gas in the modified boiler plant resulting in higher efficiency and improved environmental conditions, the company announced.
For this engineering, procurement and construction (EPC) contract, Sumitomo provided the design, supply, construction and commissioning of modifications and equipment to the existing 100 MWe CFB boiler to increase its retort gas combustion capacity to 50 % of heat input when co-firing with Estonian oil shale.
Margus Vals, Member of the Management Board of Enefit, said that the technological solution greatly increased the boilers capability to use local oil shale gas, enabling his company to decrease carbon and ash emissions.
