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. 核心优势: Core advantages:

构造与性能: Construction and Performance:
（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***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.
