Technical Information

Chip Boiler, Push (Walking) Floor Fuel Store

Push floors are extremely robust and long lasting and can handle very large wood chip pieces. The push rams are hydraulically operated and the whole package is very simple to maintain.

The system automatically loads biomass fuel into a conveyor, from where the material is fed into augers or a chain conveyor which moves the biomass fuel to the boiler as needed.

Walking floor-1
Technical Information
  • Fuel type
  • Wood chips, Poor quality, ie high water content and large particle size
  • Fuel extraction type
  • Hydraulic push ladders, each ladder is 1.8-2.2m wide and from 8m to 12m long
  • Fuel store type
  • Concrete base and walls. Typically 80-100m3 storage capacity per ladder, typically 2 to 4 ladders side by side
  • Fuel store location
  • Ground level or below ground
  • Fuel delivery vehicle
  • Large tippers or articulated with a walking floor offloader. Push floor can be ‘drive on’

Chip Boiler, Top Loader Fuel Store

This moves on top of the wood chip fuel and scrapes the top layer towards the auger screw/belt conveyor/chain conveyor which transports the chip to the boiler.

This allows for large fuel deliveries from multiple articulated vehicles, cutting down the number of deliveries per annum. It also ensures easy maintenance as the entire mechanism is above the fuel and not buried beneath like all the other options described here, so prior emptying of the fuel store is not necessary.

Toploader 2
Technical Information
  • Fuel type
  • Wood chipsHigh water content and large particle size
  • Fuel store type
  • Concrete base and wallsTypically 150-400m3 storage capacity per Toploader
  • Fuel store location
  • Ground level
  • Fuel delivery vehicle
  • Any type of vehicle but typically large articulated with a walking floor offloader.
