Stalks: Another Biomass Available for Energy Generation

Using stalks as fuel in boilers poses different challenges compared to burning fiber and husks. Stalk fibers typically have a moisture content close to 50% (once squeezed and chopped), compared to 38% for mesocarp fiber. Additionally, stalk ash contains high levels of sodium, potassium, phosphorus, and chlorine, which produce alkaline gases causing oxidation upon contact with steel at temperatures exceeding 450°C. This phenomenon can occur in superheaters and other parts designed to operate within that temperature range. Moreover, stalk ash is more abrasive, posing risks of premature wear.

At VR Engineering, we have addressed the inherent problems of using this fuel and offer a 100% safe, reliable, and effective solution for industries considering the viability of using stalks for thermal and electrical energy generation in their boilers.
