ABKH type

ABKH type boilers with a movable grate are designed to burn wet fuel up to 55% moisture content. These types of boilers are manufactured with a power range from 500 kW to 5000 kW. ABKH type boilers are equipped with two refractory arches. Due to the double arches and large fuel volume, the boiler ensures good ecological parameters.
The fuel used is wood chips, sawdust, and other solid fuels.
The control range of the ABKH model is 30%-100%.
