  • Can a 5MW biomass boiler run on mixed wood fuels? 2026-06-26
    A 5MW biomass boiler is often selected by plants that need stable heat output and have access to wood-based fuel. When the fuel source is not a single uniform material, buyers usually ask the same question: can the boiler handle mixed wood fuels, not only one specified grade? In many real projects, the answer depends on how the fuel system, furnace design, and ash handling are arranged.   Mixed wood fuels may include wood chips, offcuts, bark, pellets, and other processed wood materials. ...
  • How can a 20MW / 30 ton biomass steam boiler handle bark and wood chips with high moisture? 2026-05-15
    A 20MW biomass steam boiler for 30 t/h saturated steam is a typical demand in sawmills, wood processing plants, panel board factories, pulp-related facilities, and biomass energy projects. In this inquiry, the customer requires about 30 t/h saturated steam at 10 bar and 180°C, using bark and wood chips with moisture content that may reach 65%. The project location is Argentina. These conditions need careful review before selecting a 20MW biomass steam boiler. For 30 t/h saturated steam at a...
  • I’m interested in a new 6 t/h biomass steam boiler. What ZOZEN Boiler solution do you suggest, and can you support full project engineering? 2026-01-16

  • How does ZOZEN design reciprocating grate boilers to handle challenging agricultural biomass such as rice husk and palm shell? 2025-10-31
    Agricultural biomasses like rice husk and palm shell present combustion challenges: high ash content, significant alkali and silica leading to low ash fusion temperatures, abrasive particles, and variable moisture. ZOZEN addresses these with a furnace-grate architecture optimized for fuel-specific behavior. The reciprocating grate’s stepped motion and adjustable speed support staged drying and combustion, helping to prevent rapid surface melting that causes slagging. Robust grate bars with...
