    KSM-Multistoker XXL is fitted with 2 ash augers, one in the boiler bottom and one tilted ash auger for transporting the ash into a suitable container.

  • Page 11: Fuel

    2.0 Fuel. The KSM-Multistoker type XL are designed to use a lot of different type of fuel. The boiler are tested and approved on the Danish Technology Institute, running on wood pellets with a water content at 8%, and wood chip with a water content at 20%.. However, both our customers and we have made the experience that the use of grain will result in a very fine economy.

  • Page 14: Control Panel

    4.0 Control Panel The PCT400 control from KSM-Stoker A/S is a full modulating O controller with integrated PID regulator. The PID regulator, will on normal condition always adjust the boiler output to fit the demand from the heating system. If the demand is so low, that it exceeds the lowest output for the boiler, the boiler will go into pause mode, or if it is equipped with automatic ignition, stop and wait until there is a demand again.
