The furnace is surrounded by membrane wall, and the membrane wall on the left side of the furnace completely seals the furnace from the convection tube bundle. The membrane wall and the upper and bottom drums adopt the full sealing welding.
ZOZEN Boiler provided an energy-saving and environment-friendly WNS gas-fired steam boiler for a food enterprise in Suzhou. The gas-fired steam boiler adopts two-pass design, and the use of large-diameter corrugated furnace and threaded smoke tube make the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach more than 98%.
SZS series gas-fired boilers are the main energy-saving and environment-friendly boiler products in the market at present. In order to reduce the heat loss on the surface of the furnace body, the outer package of the gas-fired boiler adopts the whole frame structure, which reduces the connecting plate between the frame and the drum, and effectively reduces the heat loss caused by heat conduction. In addition, the outer guard plates of ZOZEN SZS series gas-fired boilers can be customized as needed.
ZOZEN ZZ series medium-temperature and medium-pressure gas-fired steam boiler adopts "D" type 2 passes. It is double-drum natural circulation water tube boiler. The flue gas turns at the back of the furnace, enters the convection tube bundle of the second pass, then leaves the boiler body, and enters the economizer and condenser in sequence.
ZOZEN Boiler provided a set of 46MW SZS series gas-fired hot water boiler for Luanchuan County Thermal Power in Henan Province. The boiler combustion chamber adopts the full membrane wall structure with a large radiation heating surface. There are also energy-saving devices at the end of the boiler, which can reduce the exhaust gas temperature and improve the overall thermal efficiency to 95% and above. In addition, with advanced combustion equipment, the boiler's nitrogen oxide emissions can be less than 30mg/Nm3. ZOZEN SZS series hot water boiler is energy-saving and eco-friendly and has a wide range of capacity, which can meet the demands of central heating in various places.
The shipment of ZOZEN SZS series of boiler. This series of steam boiler adopts a large furnace and an advanced burner to ensure the complete combustion of the fuel and improve fuel utilization. Besides, energy-saving devices are equipped at the end of the flue to improve the thermal efficiency of the boiler to more than 98%. In addition, with an intelligent control system, the boiler can realize automatic operation and automatic adjustment of steam temperature and pressure, which can realize energy saving and consumption reduction while ensuring the steam supply.
This kind of heater adopts three pass circular tube design for sufficient heating surface, and the waste heat boiler and energy-saving device disposed at the tail of the heater can greatly reduce the loss of thermal energy, the thermal efficiency can be as high as 95% or more. Advanced low NOx burner can achieve NOx emissions below 30mg/Nm³. And the operation of the thermal oil heater can realize full automatic control, and can automatically adjust the combustion, high tank level, outlet temperature and flow to ensure the safe operation. This series of thermal oil heaters are favored by all walks of life in the chemical, rubber and food industries.
SZS series boiler is designed with longitudinal double drums and " D " type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane water cooling tube wall. Furnace and tube bank are totally separated by the membrane water tube cooling wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, convection tube bank area and then from left front part enters spiral fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.
