Crane Selection for Biomass Power Plants: Fuel & Boiler Handling
In brief: Kelude Heavy Industry provides a complete crane configuration solution for biomass power plants, covering four key zones—fuel storage, boiler maintenance, turbine servicing, and ash handling—with lifting capacities from 5 to 32 short tons (4.5–29 metric tons) and spans from 12 to 36 m. Total crane equipment investment typically ranges from approximately $45,000 to $300,000. The fuel storage area is equipped with an explosion-proof grab bridge crane (5–10 short tons / 4.5–9 metric tons), the boiler zone uses a heat-resistant double-girder bridge crane (16 short tons / 14.5 metric tons), the turbine area features a QD-type double-girder bridge crane (20–32 short tons / 18–29 metric tons), and the ash handling zone is served by an MH-type anti-corrosion gantry crane (5 short tons / 4.5 metric tons)—delivering full-process lifting coverage from fuel intake to ash discharge.

Explosion-Proof Crane Design for Biomass Fuel Storage
Biomass fuels—straw, rice husk, wood chips, and similar materials—generate significant amounts of combustible dust during storage and handling, placing these areas in the explosive hazardous zone. The storage environment calls for a corrosion protection level of C4–C5. Kelude equips fuel storage areas with grab bridge cranes featuring a dust explosion-proof electrical system certified to Ex tb IIIC T120°C, along with hermetic motors and an automatic fire-suppression interlocking device. When dust concentration exceeds safe limits, the system automatically cuts off the power supply and activates the spray suppression.
Crane Selection for Boiler and Turbine Areas
In front of the biomass boiler, ambient temperatures reach 80–100°C. The LH-type explosion-proof hoist bridge crane, fitted with Class H insulated motors and a thermally insulated operator's cab, meets these demanding conditions. For the turbine hall, Kelude supplies QD-type double-girder bridge cranes with lifting capacities from 16 t to 50 t. Variable frequency inching control enables precise positioning of sensitive components such as turbine impellers during assembly. An anti-sway electronic control system reduces load swing by more than 60% during heavy lifts, ensuring accurate and safe placement.
Ash Handling Area and Plant-Wide Maintenance Solutions
Bottom ash from biomass combustion contains alkaline compounds that can corrode lifting equipment. The MH-type gantry crane addresses this with an anti-corrosion coating and a stainless steel electrical enclosure. Kelude provides unified maintenance services for all cranes across the biomass power plant, including scheduled wear inspections on grab bucket blades, quarterly checks on heat-resistant components in the boiler area, and coordinated support during turbine hall overhauls.
Kelude Service Advantages for Biomass Power Plants
With years of experience in the energy and power generation sector, Kelude delivers complete lifting solutions for biomass power plants—from fuel grab handling to turbine maintenance. Our product line spans three dedicated series: explosion-proof, high-temperature resistant, and corrosion-resistant types. To date, Kelude has supplied lifting equipment to more than 30 biomass power plants across China.
FAQ
Q: What explosion-proof rating is required for biomass fuel dust?
A: Per GB 50058-2014 and GB 15577-2018, biomass fuels (straw, wood chips, etc.) are classified as combustible dusts. Storage areas are designated as Zone 21 (areas where explosive dust clouds may form), requiring electrical equipment to meet Ex tb IIIC T120°C explosion-proof certification. Kelude's dust explosion-proof certification covers the complete electrical system, including motors, electrical control boxes, control stations, and remote controls.
Q: Do cranes for biomass boiler areas require high-temperature resistant design?
A: Ambient temperatures in biomass boiler combustion zones can reach 80–100°C. Standard crane motors (Class B/F insulation) experience significantly shortened service life under these conditions. Kelude recommends Class H insulated motors (rated for 180°C) combined with heat shields and forced-air cooling fans on the motor housing to keep temperature rise of critical electrical components within permissible limits.
Q: How does corrosiveness in the ash handling area affect crane selection?
A: Biomass ash residue has a pH of 10–12 (alkaline) and forms a caustic solution in humid conditions. Kelude recommends MH type gantry cranes with a three-layer anti-corrosion coating system: hot-dip galvanized structural members, epoxy zinc-rich primer, and polyurethane topcoat. The electrical cabinet is rated IP56, with stainless steel bolts and wire rope.
Q: How many cranes does a complete biomass power plant typically need?
A: For a typical 30 MW biomass power plant, a common configuration includes: one grab bridge crane for fuel handling (5t–10t), one high-temperature resistant overhead crane for the boiler area (16t), one QD overhead crane for the turbine hall (20t–32t), one MH type gantry crane for the ash handling area (5t), and 2–3 electric hoists for miscellaneous workstations. Kelude can supply the complete plant as a unified package to reduce management overhead.
