Charging Boilers

Econo Plus

Traditional coal boilers ECONO PLUS with fan and automatics are adapted for combustion of coal and wood. They are equipped (standard) with microprocessor controller and fan supporting fuel combustion process. Air is forced directly to the zone of charged fuel using system of blowing nozzles passing through water jacket of boiler. Use of forced draught allowed increasing of range of combusted fuels with mix of coal and fines in ratio of 30% of fines and 70% of coal as well as wood wastes. They are intended for heating of living quarters and industrial rooms from 30m to 350m2 and for generation of hot utility water.
