Multipurpose feeder is characterized by its simplicity , usability , and primarily its low maintenance . Proven universal burner 25 kW and its self-cleaning technology is able to burn different types of materials - brown coal type 2 , black coal (peas ) , wood pellets , and any small chips to 30 mm grain size .
Universal burner can be installed on all cast iron and sheet metal solid fuel boilers and for its comfort is very popular type for heating family buildings. This type of burner burns very well known agro-pellets, which have a tendency to sinter and melt. The construction is designed in a way that the feeding screw pushes the material against itself into the furnace where the combustion takes places and also the self-cleaning of the burner works. Ash and unburned material then overflows into the open side of the ashtray. This type has the best performance when burning agro-pellets, but also wood chips. Due to its design, burner can easily push out sinter and prevent any inconvinience when burning materials with this character.
Combustion is supported by air which is primarily blown from two sides, which increases its efficiency. Fuel is fed into the furnace by steel screw conveyor and together with the air, system burns the fuel. The whole technology works on the princip of the blacksmith forge . Tank of nominal capacity 250 l ensures a long life . Automatic mode allows endurance of the tank up to four days during normal operation of the house and unmanned service. Driving of this system provides electric motor with gearbox, which is a guarantee of low operating costs.
Automatic operation of universal burner is protected against back burning by protective sensor on the feeder will stop and block the fan when temperatures above 70° C. Protective sensor on the outcoimng flue also stop the fan when temperature of the boiler goes over 92° C. At both cases system runs only auger and rolls up all the material from the furnace burner to ashtray. The biggest protection against back burn is also in the fact that whole system is hermetically sealed to prevent any access of air to the tank or the feeder. Additional mechanical protection valve is used for safery and back burn, either bimetallic fuse or wax plug which will pour water from separate tank to extinguishthe fire.
