Straw fired plants are gaining momentum as a reliable, efficient and environmentally acceptable power generation technology. Sustainable fuels that can lead to immediate savings of CO2 emissions are primarily constituted of agrofuels having a one year carbon cycle. Hence the carbon footprint of plants able to use these difficult and slagging fuels is very low. BWE engineers has since the 80’ties developed and delivered straw based boiler islands and the last generation of proven design 120 MWth boilers have even steam data of up to 120 bar, 540°C providing electric efficiencies at 34%. The development stages are supported by the reliability shown from the previous plants featuring slagging austenitic superheaters operated for more than 15 years of continuous operation without major repair or exchange of these adding to low operational costs for such difficult fuels. In the recent years BWE has delivered straw fired Boiler Islands in Germany and the UK and recently won a contract for the largest straw based CHP boiler island in Denmark. It also features flue gas condensing in combination with combustion air humidification to improve the energy efficiency. The latter has never before been demonstrated on a straw fired plant.
