■ product news HoSt Reveals New Bioenergy Plant HoSt reports it has succeeded, after a decade of research, development and innovation, in developing a high-tech bioenergy plant with highly innovative NO-NOx thermal energy conversion HoSt innovates with thermal of residual wood and residual waste streams. conversion technology and develops clean bioenergy plant Highlights include: l The technology achieves NOx (nitrogen oxides) emissions at less than 95% of the emission of natural gas: <2.2 mg/Nm3 well below the national emission limits of 145 mg/Nm3 l kNH3 slip (ammonia) of <0.06 well below national emission limits of 30 mg/Nm3 l Particulate emissions of 0.5 mg/Nm3 well below national emission limits of 5 mg/Nm3 l Distinctive innovative NO-NOx thermal conversion technology l CO2 capture for utilization, sales or storage possible (liquid and gaseous) l Fuel: regionally available residual and pruning wood and other residual streams from for example sawmills, RDF, and agricultural waste HoSt’s mission is to remain at the forefront of hightech energy conversion from low-value unused residual streams that are available in abundance worldwide and for which no alternatives are available. The 15 MW bioenergy plant in Andijk, Netherlands with NO-NOx thermal conversion technology is the product resulting from years of research and innovation. Independent measurements show that the plant produces energy from prunings and residual waste wood with a NOx emission reduction of >99%. This is achieved by HoSt NO-NOx technology in combination with ultra low-NOx innovative combustion technology, precise combustion temperature control and highly automated control. In addition to clean conversion and very high availability, the HoSt design ensures streamlined fast construction on site due to its modular and innovative construction, resulting in lower costs. Wouter Kok from HoSt, an expert in the field of thermal conversion technology and responsible for the sales of the innovative bioenergy plant, explains, “It is not the application of only a baghouse filter that makes the plant exceptional. We achieve these lowest emissions through innovation in combustion technology and our innovative furnace, which creates a perfect mixing of flue gases with combustion air and a very high efficiency. Thanks to the clever configuration of the combustion zones on the grate, the three-stage combustion in the furnace in combination with flue gas recirculation, high peak temperatures are avoided, and the for-
