Wood pulp - Import export

This new addition to our product line is a compact heat exchanger made from high-alloyed stainless steel and can handle temperatures up to 550°C. Its compact and modular design makes it extremely versatile and easy to service. Our exhaust gas heat exchanger is designed to recover heat from exhaust gas produced for example by combustion engines used in combined heat and power plants. The heat exchanger transfers the heat from the exhaust gas to a liquid (water or water-glycol solutions). When heated up, this liquid can be used in central heating systems; for preheating air in the combustion chambers of furnaces and turbines; to dry coal, pulp, wood and other materials as well as for generating electricity with a Rankine process.

Various heater types available, eciency and robustness characterise directly heated drum dryers by Büttner. They are used for drying wood particles, strands, sugar beet pulp and all free-owing types of wood, biomasses and bulk solids Features Water evaporation capacity of up to 80 t/h depending on the product Direct heating system with multi-fuel burners in combustion chambers Direct heating system using ue gases from energy plants Direct heating system using waste gases from turbines or engines All combinations of these types of heaters are possible. A ash tube may be used for pre-drying and oversize separation of material that is quite moist. Material separation via cyclones or drop boxes Function The material to be dried is admitted through an air-tight rotary air lock into a rotating single-pass drum dryer. The dryer drum can be tted with specic internal ights to suit the material to be dried. This results in an increase in surface area and thus an increase in eciency
