产品简介 Product Introduction:

SZS型燃气蒸汽锅炉采用汽包纵向布置结构,分为锅炉本体和节能装置两部分。锅炉本体模块化设计,实现了大容量锅炉的整体快速安装,缩短了安装周期,节省了安装成本

The SZS type gas steam boiler adopts a longitudinal arrangement structure of the drum, which is divided into two parts: the boiler body and the energy-saving device. The modular design of the boiler body realizes the overall fast installation of a large capacity boiler, shortens the installation cycle, and saves installation costs.

锅炉内部采用全膜式壁水冷结构,气密性好,减小锅炉主机重量和外形尺寸,缩短启动和停炉时间。

The boiler adopts a full membrane wall water-cooled structure inside, which has good airtightness, reduces the weight and external dimensions of the boiler host, and shortens the start-up and shutdown time.

三回程对流管束结构,合理的烟气流程,较低背压,实现了正压燃烧,尾部布置可分式节能器,降低了排烟温度,避免了本体受热面的低温腐蚀。

The structure of the three return convection tube bundle, reasonable flue gas flow, low back pressure, and positive pressure combustion are achieved. A detachable energy-saving device is arranged at the tail to reduce the exhaust temperature and avoid low-temperature corrosion of the heating surface of the body.

大炉膛和对流管束二回程设计,使烟气在炉膛内停留时间加长,可燃气体得到充分燃烧,提高了燃烧效率。锅炉设有节能器,进一步提高热效率。

设计中采用了较大的水容积,保留了较大的水位安全范围,使得蒸汽蒸发面大,蒸汽含水率低,保证了蒸汽品质,有效减少了用汽侧负荷骤变对炉内水位的冲击

膜式水冷壁外安装轻型保温材料,采用特种复合硅酸盐板覆盖,外挂彩钢板,保温效果好,外观美观。

全自动PLC控制,触摸屏高清显示,一键启停,负荷自动调节,各类故障连锁保护。

配备低氮燃烧器,采用烟气外循环(FGR)技术

锅炉受压本体应力状况良好,锅筒等重要受压元件不直接受高温火焰辐射和冲刷,受压元件伸缩自如,热应力小,实现更高的安全裕度。

The design of a large furnace and convection tube bundle with two return paths prolongs the residence time of flue gas in the furnace, allowing for sufficient combustion of combustible gases and improving combustion efficiency. The boiler is equipped with an energy-saving device to further improve thermal efficiency.

A larger water volume was adopted in the design, retaining a larger water level safety range, resulting in a larger steam evaporation surface and lower steam moisture content, ensuring steam quality and effectively reducing the impact of sudden changes in steam load on the water level in the furnace

Light insulation material is installed outside the membrane water-cooled wall, covered with special composite silicate board, and coated with color steel plate. The insulation effect is good and the appearance is beautiful.

Fully automatic PLC control, high-definition touch screen display, one click start stop, automatic load adjustment, and various types of fault chain protection.

Equipped with low nitrogen burners and utilizing flue gas external circulation (FGR) technology

The stress condition of the pressurized body of the boiler is good, and important pressure components such as the drum are not directly affected by high-temperature flame radiation and erosion. The pressure components can stretch and contract freely, with low thermal stress, achieving higher safety margins.


构造与性能 Construction and Performance:

低氮燃气蒸汽锅炉3.png

(1)内部结构:

采用上下锅筒纵向布置,上下锅筒间设有对流管束。下锅筒置于锅筒座上,与底座相连,上锅筒通过对流管束支撑在下锅筒上。

(1) Internal structure:

Adopting a longitudinal arrangement of upper and lower drums, there is a convection tube bundle between the upper and lower drums. The lower drum is placed on the drum seat and connected to the base. The upper drum is supported on the lower drum through a convection tube bundle.

(2)水冷壁结构:

锅炉炉膛为膜式水冷壁结构,膜式壁采用专门的膜式壁生产线生产,焊缝波形均匀美观,质量好确保焊接及成形质量。全膜式壁水冷结构,气密性好完全消除烟气泄漏,保证了结构的稳定性,提高炉膛及烟道刚性,提高锅炉炉壁的抗爆能力。

(2) Water cooled wall structure:

The boiler furnace adopts a membrane water-cooled wall structure, and the membrane wall is produced by a specialized membrane wall production line. The weld waveform is uniform and beautiful, and the quality is good to ensure the welding and forming quality. The full membrane wall water-cooled structure has good airtightness and completely eliminates smoke leakage, ensuring the stability of the structure, improving the rigidity of the furnace and flue, and enhancing the blast resistance of the boiler wall.

(3)烟气系统:

锅炉采用了大炉膛和对流管束二回程设计,使烟气在炉膛内停留时间加长,可燃气体得到充分燃烧,提高了燃烧效率。炉膛与对流管束通过水冷壁分开。高温烟气首先在炉膛内与水冷壁进行高效换热,避免了直接高温烟气直接冲刷锅筒,延长了锅炉的使用寿命;烟气在经后烟箱进入二回程对流管束,进一步散热;流经对流管束后,烟气离开锅炉本体,通过连接烟道进入尾部受热面(节能器等热回收装置),再进入烟囱排入大气。

(3) Smoke system:

The boiler adopts a large furnace and convection tube bundle two return design, which prolongs the residence time of flue gas in the furnace, fully combusts combustible gases, and improves combustion efficiency. The furnace and convection tube bundle are separated by a water-cooled wall. High temperature flue gas first efficiently exchanges heat with the water-cooled wall in the furnace, avoiding direct flushing of the boiler drum by high temperature flue gas and prolonging the service life of the boiler; The smoke enters the secondary convection tube bundle through the rear smoke box, further dissipating heat; After passing through the convection tube bundle, the flue gas leaves the boiler body and enters the tail heating surface (such as the energy-saving device) through the connecting flue, and then enters the chimney to be discharged into the atmosphere.

The triple overpressure protection device includes remote pressure alarm, mechanical pressure switch alarm, and spring fully open safety valve to ensure that the boiler operates within the rated pressure.

On both sides of the boiler, a water level gauge is connected through a balance bucket. Multiple types of water level gauges, such as plate, dual color, and float, are available. The water level observation is intuitive, the detection is stable, and the control is sensitive

A dedicated water distributor is installed at the inlet of the boiler feed water, which disperses and evenly enters the boiler after passing through the distributor, avoiding local temperature drops during feed water.

By adopting a reasonable flue structure, the condensed water generated by gas combustion quickly collects and is discharged from the front and rear smoke boxes, greatly reducing the corrosion of condensed water on the boiler

Manholes, handholes, and other inspection holes are fully installed, reasonably positioned, and easy to maintain and repair.
