The push grate is specially designed for open bottom boilers.<\/span><\/p>\n

Depending on the grate size, the push grate can be supplied with 1 or 2 grate trolleys.<\/span><\/p>\n

Secondary air system, recirculation air system and hydraulic station are ordered separately depending on the fuel bed and water content.<\/span><\/p>\n

The push grate is equipped with a bricked-in firebox, which ensures that the combustion chamber temperature is kept at an optimal level for combustion.<\/span>[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image media=”254″ media_width_percent=”100″ uncode_shortcode_id=”123962″][\/vc_column][\/vc_row][vc_row row_height_percent=”0″ override_padding=”yes” h_padding=”2″ top_padding=”3″ bottom_padding=”3″ overlay_alpha=”50″ gutter_size=”3″ column_width_percent=”100″ shift_y=”0″ z_index=”0″ uncode_shortcode_id=”209297″][vc_column width=”2\/3″][vc_custom_heading text_color=”color-547383″ text_font=”font-162746″ uncode_shortcode_id=”550979″ text_color_type=”uncode-palette”]Complete wood chip framing system[\/vc_custom_heading][vc_column_text text_color=”color-547383″ uncode_shortcode_id=”131683″ text_color_type=”uncode-palette”]Single hopper for receiving wood chips, with hydraulic discharge at the bottom, for dosing hopper. Also available as a double funnel.<\/span><\/p>\n

Hydraulically operated fire damper equipped with an accumulator, which ensures that the damper also shuts off in the event of a power failure.<\/span><\/p>\n

The dosing tank is equipped with an infrared level control and an automatic sprinkler system that is activated if the temperature in the dosing tank becomes too high, e.g. due to fire.<\/span><\/p>\n

Hydraulically driven pusher, which pushes the material from the dosing hopper through the water-cooled channel into the boiler box. The pusher runs in step or frequency controlled mode, the size of which depends on the boiler load, ensuring a completely even feeding of the fuel.<\/span><\/p>\n

Water-cooled duct to ensure a “chip plug” between the pusher and the combustion grate, thus preventing false air intake. The water-cooled duct ensures that the system can withstand a backfire without risk of breakdown. At the transition from the water-cooled duct to the pusher, a number of fire nozzles are placed to further protect against backfire. The duct is built and secured according to the pressure\/temperature of the boiler and is connected directly to the boiler circuit.<\/span>[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image media=”136″ media_width_percent=”100″ uncode_shortcode_id=”865073″][\/vc_column][\/vc_row][vc_row row_height_percent=”0″ override_padding=”yes” h_padding=”2″ top_padding=”3″ bottom_padding=”3″ overlay_alpha=”50″ gutter_size=”3″ column_width_percent=”100″ shift_y=”0″ z_index=”0″ uncode_shortcode_id=”209297″][vc_column width=”2\/3″][vc_custom_heading text_color=”color-547383″ text_font=”font-162746″ uncode_shortcode_id=”136895″ text_color_type=”uncode-palette”]CHIP-BARK PUSHER[\/vc_custom_heading][vc_column_text text_color=”color-547383″ uncode_shortcode_id=”171411″ text_color_type=”uncode-palette”]The piston of the pusher is driven by double-acting hydraulic cylinders.<\/span><\/p>\n

The pusher pushes the material from the dosing hopper through the water-cooled\/cast channel to the combustion grate.<\/span><\/p>\n

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.<\/span><\/p>\n

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.<\/span><\/p>\n

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.<\/span><\/p>\n

The pusher is equipped with a system that prevents backfire by controlling the temperature of the feed system.<\/span><\/p>\n

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.<\/span><\/p>\n

The system runs automatically. However, it may be necessary to clean the dosing system after a fire.<\/span><\/p>\n

The chip pusher is used for feeding solid fuels such as bark, shavings, wood chips into combustion grates:<\/span><\/p>\n
