WBT series heat systems generate heat energy from woody biomass, nut shells, sunflower hulls, corn cob and similar types of biomass. Producer gas output is supplied to burners for thermal applications such as boilers and calciners. These plants are based on WBG gasifier systems and equipped with gas or dual-fuel burners. Their heating capacity ranges from 0.25 to 7.5 MWth when running on 100% producer gas (higher with co-firing).
