WNS series oil and gas boilers are characterized by safety, reliability, high efficiency, energy saving, environmental protection, convenient maintenance, durability and automatic intelligent control. After painting, the boilers will be delivered to users, and the installation cycle will be greatly shortened.
WNS series gas-fired boilers have exquisite outer packaging, the furnace temperature is controlled below 45℃, and thermal insulation materials with limited control of heat loss. The assembled ZOZEN gas boiler will be finally packaged in the outer packaging area, which is mainly divided into three steps. First of all, ZOZEN workers wrap the furnace body with aluminum silicate fiber, and then use refractory mud to keep it warm. Then, according to the size of the boiler, cut the stainless steel sheet into a suitable size, and then package the furnace tightly.
The compact 20-ton gas-fired boiler is a fire-tube internal combustion boiler with simple structure, compact size and small floor space. The use of corrugated furnace makes the combustion chamber larger, and it can adapt to advanced low-nitrogen burners, so that the emission of nitrogen oxides can be controlled below 30 mg/nm.
ZOZEN WNS gas-fired and oil-fired boiler is an energy-saving boiler type, with the capacity of 1-20t/h, and the working pressure of 0.7-2Mpa, the boiler has the advantages of stable heat supply, good performance of energy conservation and low emission.
The boiler is additionally provided with an air preheater at the end of the flue gas, and the air is preheated to a certain temperature with the heat carried by the flue gas of the boiler. The heated air enters the combustion room again, which not only accelerates the drying, ignition and combustion processes of the fuel, ensures the stable combustion in the boiler, but also improves the average temperature level in the boiler, thereby strengthening the radiation heat transfer in the boiler and effectively improving the thermal efficiency of the boiler.
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 WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas-fired boiler. Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power the stress and expand boilers working life.
