Furnace ModEco 4-60

Synergy Dream, which main type of business is the design and manufacture of charcoal burning equipment represents a charcoal burning kiln, ModEсo 4-60 model. The kiln is intended specifically for receiving charcoal from large-sized wood with a relative moisture content of up to 25 %.

The main parts of the kiln are a hearth and two pyrolysis sections accommodating two stationary retorts each. The hearth is a metal enclosure, which walls and bottom are lined with high temperature insulant.

    The following materials are used for lining:

  1. ceramic fibre with an operating temperature of up to 1,250 0C,
  2. ceramic plates with an operating temperature of up to 1,250 0C,
  3. firebrick ShA 5.

Pyrolysis sections also represent metal enclosures, with retorts installed inside (retort is a vessel where thermal decomposition of wood occurs). Retorts are made of steel 09 G2S, 12 mm thick. Pyrolysis section walls, where the operating temperature reaches 600 °C are lined with ceramic fibre with an operating temperature of up to 1,050 °C. The kiln is operated only with the ACS (automated control system). The ACS monitors operating modes and maintains temperatures within set ranges. Coal is discharged to metal boxes, so called quenchers. To stabilize coal, metal stabilizers are used. Quenchers and stabilizers guarantee high processability provided that the coal cooling and stabilization procedures are followed.
