Power plants and biomass
For biomass, coal and waste-to-energy plants: conveyor chains for fuel and ash, fabric expansion joints in the flue-gas path and insulation to 1000 °C — from one source.
In power plants, abrasive fuel, hot ash discharge and large flue-gas cross-sections all come together — every component has to withstand heat and wear. SENN supplies conveyor chains, expansion joints and insulation for the entire hot path from one source.
Applications in detail
- Fuel intake & handling: wear-resistant conveyor chains for wood chips, refuse-derived fuel and coal.
- Flue-gas path: fabric and metal expansion joints absorb the thermal movement of large duct cross-sections.
- Boilers & ducts: high-temperature insulation and removable textile jackets, rated to 1000 °C.
- Ash discharge: drag and scraper chains for hot, abrasive discharge.
- Bulk & discharge: forked-link and drag chains for fuel, residues and hot ash discharge.
- Contact protection: high-temperature fabrics and textiles on hot surfaces and fittings.
- Back-up insulation: calcium silicate as dimensionally stable insulation behind the hot zone.
- Grate & fluidised-bed firing: conveyor chains and insulation for grate, fluidised-bed and pulverised-fuel firing.
Why SENN
- Conveyor chains, expansion joints and insulation from one house — one partner for the whole hot run.
- Made in Erl, fabricated to drawing.
- Chains from EU steels; insulation to 1000 °C (silica), ceramic-fibre ceiling 1260 °C.
- Removable insulation for turnarounds, tool-free mounting.
- High-temperature fabric and calcium silicate complete the compensators and insulation for the whole hot zone.
Service & Installation
- On-site survey: measuring components, lines and conveyor runs before production.
- Turnaround service: replacement and repair during plant revisions and shutdowns.
- Custom fabrication to drawing: production to drawing, sample or measurement from Erl.

Frequently Asked Questions (FAQ)
Which components do you supply for boilers and flue-gas ducts?
High-temperature insulation and removable textile jackets up to 1000 °C for boilers and ducts, plus fabric and metal expansion joints for the thermal movement of large cross-sections. All from one source.
Do the conveyor chains handle abrasive fuel and hot ash discharge?
Yes. Wear-resistant conveyor chains move wood chips, refuse-derived fuel and coal; drag and scraper chains handle the hot, abrasive discharge. Chains from EU steels.
Can the insulation be removed for maintenance?
Yes. Removable insulation fits without tools and goes back on after the overhaul. Custom-made to drawing, made in Erl.
Which chains do you use for hot ash discharge?
Drag chains for the hot, abrasive discharge, plus forked-link chains for fuel and residue transport. Chains from EU steels.
