水冷前烟箱常压卧式中心回焰燃油燃气锅炉的设计

Design of Atmospheric Pressure Horizontal Centrally-back Flame Oil (gas)-fired Boiler with Water-cooled Frontal Gas Chamber

简要介绍了目前常用的常压卧式中心回焰燃油、燃气锅炉的优缺点,针对锅炉使用过程中出现的前烟箱易过热烧损的问题,充分利用常压锅炉结构灵活的特点,对锅炉的结构在原有基础上进行了改变,摒弃了一贯采用的用耐火材料填充前烟箱的方法,将前烟箱设计成水夹套的形式,并与锅筒联成一体,用锅筒内的循环水对前烟箱进行冷却,整个结构设计简单明了,安全性高,制造工艺简单,解决了前烟箱存在的问题。

Advantages and disadvantages of atmospheric pressure horizontal centrallyback flame oil (or gas)firded boiler used at present are introduced in brief. The frontal gas chamber is easy to be overheated and ablated in using, aim at this problem and utilize the characteristics of this boiler's flexible structure sufficiently, the boiler is changed at basis of original structure. The normal means of using refractory materials to be filled in frontal gas chamber is abandoned, frontal gas chamber is designed as water leg and joined with drum. The frontal gas chamber is cooled by drum's return water. This design has simple structure?simple manufacture technics and high safety, and the existent problem of frontal gas chamber is solved.
