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 WNS series oil-fired and gas-fired boiler is designed with large-diameter corrugated furnace and threaded smoke tube, which makes the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach over 98%, which is well received by the market.
Recently, the spot supply of ZOZEN gas-fired boiler solved the urgent problem of the unstable steam supply of biomass gasification boiler during the upgrading and reconstruction of the central heating project. ZOZEN SZS series gas-fired boiler of this tonnage is mainly composed of boiler body, connecting smoke tube, burner, steam-water system, instrument, economizer and condenser. The boiler system has the characteristics of high thermal efficiency, sufficient output, green combustion, pollution-free emission and fully automatic operation.
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.
Thermal oil heaters, also known as organic heat carrier boilers, adopt the organic heat carrier as heat medium to realize heat transfer. Due to the high temperature characteristics of organic heat carrier, thermal oil heaters can realize low-pressure and high-temperature heating with an oil output temperature of 350℃. Thermal oil heaters adopt injection-type forced circulation system and heat exchange surface adopts round and square coil structures, which also have a wide fuel adaptability of oil, gas, coal, biomass. ZOZEN Boiler, as a leader in the boiler industry, has improved and upgraded its YQW series, YQL series and YLW series thermal oil heaters applied in the chemical industry to meet the production demands of chemical enterprises. They are equipped with complete operation control and safety monitoring devices which can precisely control the working temperature to ensure boiler's safe operation. They are popular among and favored by chemical enterprises.
Relying on the industry-university-research cooperation and large-scale production, ZOZEN has manufactured more than 400 varieties of specifications of industrial boilers including gas-fired boilers, coal-fired boilers, biomass-fired boilers and thermal oil heaters.Develop up to now, the annual production scale of ZOZEN has exceeded 2,000 sets and 25,000 tph.
