SZL series chain grate boiler can burn both the coal fuel and the biomass fuel. The boiler capacity is 4 tons to 35 tons. ZOZEN SZL series biomass-fired steam boiler has the advantages of compact structure, safe operation, high efficiency and sufficient output.
Chain grate is a common mechanized combustion device, which is used in biomass-fired boilers, coal-fired boilers and thermal oil heaters. ZOZEN chain grate is designed and produced independently, with reasonable structure and exquisite material selection.
Chain grate is a kind of common mechanized combustion equipment, which is used for biomass boiler, coal-fired boiler and thermal oil heater. The grate is used to make the solid fuel burn evenly. The fuel enters the grate through the hopper, and enters the hearth with the movement of the grate to start the combustion process. According to different fuels, ZOZEN Boiler also designs different grate widths and lengths and air distribution systems to ensure that the fuels can be stably ignited and fully burned.
ZOZEN Boiler is a well-known industrial boiler manufacturer in China. With more than 30 years' development, ZOZEN Boiler has excellent team and advanced equipment, strong design and manufacturing strength with reliable boiler quality. ZOZEN Boiler owns gas-fired boilers, biomass-fired boilers, coal-fired boilers and thermal oil heaters, which are widely used in various industries.
The dust removal door is also called the soot door, it is set up for the biomass-fired and coal-fired boiler for cleaning the dust and ash. The operator can check the ash accumulation status of the boiler and clean the ash and coke. Commonly, the dust removal door of the packaged boiler will be installed before delivery.
ZOZEN YLW series coal-fired and biomass-fired chain grate thermal oil heater is favored by Indonesian customers because it has the features of high temperature and low pressure, precise temperature control and high quality. Heater proper and chain grate are transferred separately. The pictures show the heater proper is on the delivery. YLW series thermal oil heater adopts the square coil structure to realize high safety and sufficient heating surface. The tubes are firstly bent by CNC 3D tube bending machine, then welded to link together without forced assembly. YLW series thermal oil heater adopts the structure of a large furnace to achieve sufficient combustion and realize the thermal efficiency of over 85%. It is available for the bituminous coal, anthracite, all kinds of biomass particles, sawdust, etc.
ZOZEN DZL series packaged boiler is horizontal three-pass water and fire tube chain grate boiler with a wide fuel adaptability to biomass particles, bituminous coal, meagre coal and anthracite. The boiler proper is a longitudinal single drum. The threaded smoke tubes in the drum form the convention heating surface. The drum and water-cooled walls on both sides form the radiation heating surface in the furnace. The combustion equipment adopts the light chain grate. The boiler is reasonably arranged with primary air and secondary air, and is equipped with economizer and dust collector at the boiler end to control the NOx emission concentration below 200mg/m3. Meanwhile, the boiler realizes the stepless speed regulation of the grate via the electric control. There are also the absolute rating alarm and interlocking protection functions to make the boiler safer. It is widely used in the chemical, food, tobacco, textile, printing and dyeing, feed, medicine and building materials industries.
