An air preheater is used to preheat the fuel which further increases the boiler efficiency. It is designed to heat air before another process by extracting the waste heat from the flue gases leaving the boiler to effectively reduce the flue gas temperature and improve the thermal efficiency.
ZOZEN SZS series gas-fired and oil-fired steam boiler has the advantages of high efficiency and energy saving. This series of boiler adopts double drum with full membrane structure. The SZS series boiler adopts flue gas backflip technology, with the economizer and condenser to improve the thermal efficiency to 98% and above.
Jiangsu Zhongmei Cable mainly produces power cables, fire-retardant cables for coal mines, various flame-retardant and fire-resistant special wires and cables. As we all know, ZOZEN boiler has advanced manufacturing technology and complete equipment, the service life of the boiler is very long. After the inspection at ZOZEN boiler, Jiangsu Zhongmei Cable ordered two sets of 6 tph SZS condensing gas-fired boilers, which can fully improve thermal efficiency.
Bolivia is the highest average altitude country in the world, local Bolivian companies have higher requirements for boilers than general boilers. As the altitude increases, the atmospheric pressure and the air density decrease accordingly, which adversely affects boiler combustion.
In view of this situation, ZOZEN technical team makes adjustments from the combustion system and exhaust system of boiler, fully considering the influence of low air pressure on boiler body design and combustion. By appropriately increasing the volume of the furnace to extend the residence time of the fuel in the furnace, and the problems of slow fuel burning speed and long burning time are solved.
This series of double-drum steam boilers adopts a full membrane wall structure with good sealing performance. It is designed with large furnace to ensure full combustion of fuel and the thermal efficiency is over 98%. Meanwhile, this series of gas-fired steam boilers has reliable water circulation. Besides, the arrangement of various safety devices such as explosion-proof doors and flame detectors make the boiler operation safer and more reliable.
The boiler body of WNS series boilers adopts wet-back structure. The combustion, water level, temperature and steam pressure of the boiler are automatically adjusted and protected, which can realize fully automatical operation to ensure safety and reliability. The large-diameter corrugated furnace of this boiler ensures sufficient combustion of natural gas. Combined with an advanced low NOx burner, it can easily achieve the requirement of NOx≤30mg/Nm3. In addition, the boiler is also equipped with energy-saving equipment at the end of the boiler flue, so that the boiler thermal efficiency can reach over 98%.
Steam boilers play a key role in the production process of dye intermediates, proving steam for synthesis, drying and other processes. SZS gas-fired water tube boiler adopts the structure of membrane water wall for better sealing effect and higher thermal efficiency; In addition, to effectively reduce the NOx emission, the boiler is equipped with a large volume furnace and an advanced NOx burner imported from Europe, so the NOx emission can reduce to 30mg/Nm3.
The production processes of textiles such as drying, shaping, printing, etc require stable heat source support. WNS series gas-fired steam boilers feature fully automatic and safe operation to ensure the stability of the heat source during the production process. At the same time, the gas-fired boiler has remarkable energy-saving and environmental protection effects, the thermal efficiency can reach over 98%, and the NOx emission can be as low as 30 mg/m³, which fully meets the needs of the environmental protection era.
