According to the different performance parameters, ZOZEN SZS series gas-fired boilers can be divided into self-contained, assembled and shipped in bulk. ZOZEN SZS series double drum vertical gas-fired watertube boiler is a typical medium and large-sized gas-fired boiler, with a capacity of 20-110t/h and a pressure of 1.25-5.3MPa, which meets the needs of steam and heating for most enterprises. The SZS gas-fired boiler shipped to Hebei this time was delivered in bulk, and the photos show the drum, an important pressure-bearing component of the boiler, which plays the role of steam-water separation.
SZS series gas-fired boiler is one of the popular boiler types of ZOZEN Boiler, which has the features of high heat efficiency, clean emission and full-automatic operation. This series of gas-fired boiler adopts large volume of combustion chamber and membrane structure, with sufficient combustion space and large heat transfer area, it effectively improves the fuel utilization rate.
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.
ZOZEN WNS series gas-fired (oil-fired) boilers adopt large diameter corrugated furnace for sufficient fuel combustion; euqipped with low NOx burner, the thermal efficiency is over 98%, and the ultra-low emission of NOx is easy to achieve.
