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.
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.
Relying on the scientific and technological innovation and cooperation with Shanghai Jiaotong University, ZOZEN Boiler develops the new generation of biomass boilers, which not only solves the problems such as the furnace arch and door burning out, hopper burning and feed stopper coking, but also improves the biomass boiler performance.
A set of industrial boiler with sufficient output and stable heating supply can directly affect the daily production of a food company. ZOZEN DZL series biomass-fired steam boiler adopts the single-drum longitudinal layout and chain grate stratified combustion method. ZOZEN technicians has optimized the design of the feed hopper, grate width and length, speed of grate reducer and position of secondary air outlet by analyzing the different fuel characteristics and practical use requirements of customers to ensure the sufficient combustion of biomass pellets and improve the combustion efficiency. Meanwhile, DZL series biomass fired steam boiler adopts the thread smoke tubes developed by ZOZEN to strengthen the heat transfer and improve the thermal efficiency. The heat transfer coefficient of thread smoke tube is 1.8 times higher than that of ordinary smoke tube and the thermal efficiency of boiler is over 88%, which can fully meet the daily production demands of enterprises.
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.
The shipment of ZOZEN SZL series chain grate boiler for R.R.P AGRO FARM.SZL series of biomass-fired boiler is one of ZOZEN’s patented products. It has the characteristics of wide fuel adaptability, less occupied area, convenient installation and high thermal efficiency. ZOZEN biomass-fired boiler is suitable for a variety of fuels such as biomass pellets, wood blocks, palm shell, rice husks, corncobs and wood waste. In order to improve the overall efficiency of the boilers, ZOZEN rationally designs different feeding systems according to the characteristics of different biomass fuels. By extending the furnace arch, increasing the height of the furnace, adjusting the width and length of grates, etc., ZOZEN has taken the lead in solving the problems commonly occurred in conventional biomass-fired boilers, such as furnace arch burning down, furnace door burnout, backfire in hopper tempering and tube shell coking.
