Biofuel bunkers

Description

Biofuel bunkers are designed for drying loose materials or for installation next to a standing boiler. The bunkers operate on the principle of gas generation. Biofuel bunkers are designed to burn solid fuel up to 55% moisture content.

Biofuel bunkers are manufactured with a power range from 1000 kW to 6000 kW. The solid fuel used is wood chips and residual shredded wood.

Bunker specification and functions:

  • The bunker operates on the principle of direct combustion, based on gas generation.
  • Biofuel bunkers are designed to burn solid fuel up to 55% moisture content.
  • The bunker is divided into 3 interconnected zones: 1) drying; 2) fuel pushing; 3) combustion.
  • Fuel is delivered to the bunker mechanically, using a hydraulic fuel feed device.
  • The bunker is of the moving grate type.
  • The bunker can be cooled by air or thermofication, depending on the existing system.
  • An automatic ash removal system allows for quick and easy removal of ash from the combustion process.

Boiler automation control capabilities:

  • Operation of the fuel storage and conveyors.
  • Fuel dosing into the bunker.
  • Hydraulic system for the grate.
  • Ash removal from under the grate.
  • Maintenance of the set draft in the bunker.
  • Smoke recirculation (optional).
  • Sending emergency messages via GSM.
  • The combustion process is automatically controlled throughout the load range, according to the set bunker parameters.
  • Remote control of the bunker (via the internet).
