CHIP-BARK PUSHER
The piston of the pusher is driven by double-acting hydraulic cylinders.
The pusher pushes the material from the dosing hopper through the water-cooled/cast channel to the combustion grate.
When the fuel has been pushed in at full piston stroke, the piston moves back to the starting position and a new portion of fuel can be introduced.
The cycle is repeated continuously as operation of the pusher. This runs in a run/pause step, the size of which is dependent on the boiler load.
The speed is set automatically from the control panel and is temperature dependent on the boiler flow temperature. The position of the piston rod is controlled by sensors. The temperature in the outlet of the pusher is monitored by thermostat, both electrical and mechanical.
The pusher is equipped with a system that prevents backfire by controlling the temperature of the feed system.
Automatic sprinkler system is activated if the temperature in the dosing tank becomes too high (above 95oC). A BVTS valve will open to extinguish the fire. The valve will close when the temperature in the dosing system is low again and operation can be resumed.
The system runs automatically. However, it may be necessary to clean the dosing system after a fire.
The chip pusher is used for feeding solid fuels such as bark, shavings, wood chips into combustion grates.
-wet bark, wood chips and shavings - moisture content 35% - 65%, grain size up to 10x20x350 mm.
-The pusher is available in several sizes.
-Legs for the pusher are available with adjustable feet.
