Abstract

本实用新型涉及一种循环流化床锅炉羽翼形水冷壁管,包括水冷壁管和鳍片,鳍片连接相邻的两根水冷壁管,其特征在于,在每个水冷壁管中心线上垂直设有一条钢条。本实用新型的优点是能防止和改善循环流化床锅炉固有存在的炉内水冷壁管严重磨损的问题。

Description

循环流化床锅炉羽翼形水冷壁管
技术领域
本实用新型涉及一种循环流化床锅炉羽翼形水冷壁管,属于循环流化床锅炉防磨技术领域。
背景技术
由于循环流化床锅炉的燃烧特点与常规煤粉炉不同,炉内受热面采用传统的膜式水冷壁,易引起水冷管磨损,循环流化床锅炉炉内受热面磨损是严重影响锅炉经济、安全、可靠运行的主要因素。
发明内容
本实用新型的目的是发明一种防止和改善炉内水冷壁管严重磨损的循环流化床锅炉羽翼形水冷壁管。
为实现以上目的,本实用新型的技术方案是提供一种循环流化床锅炉羽翼形水冷壁管,包括水冷壁管和鳍片,鳍片连接相邻的两根水冷壁管,其特征在于,在每个水冷壁管中心线上垂直设有一条钢条。
本实用新型采用在传统的膜式水冷壁管的外壁,沿管子的中心线上焊有一条羽翼形的钢条,以改变壁面的烟气流向,防止烟气冲刷引起的受热面磨损。对新产品的设计、制造及已运行锅炉的改造都易于实施。
本实用新型的优点是能防止和改善循环流化床锅炉固有的炉内水冷壁管严重磨损的问题。
附图说明
图1为循环流化床锅炉羽翼形水冷壁管结构示意图;
图2为循环流化床锅炉羽翼形水冷壁管俯视图。
具体实施方式
以下结合附图和实施例对本实用新型作进一步说明。
实施例
如图1、2所示,为循环流化床锅炉羽翼形水冷壁管结构示意图,所述的循环流化床锅炉羽翼形水冷壁管,由水冷壁管1、鳍片2和钢条3组成,鳍片连接相邻的两根水冷壁管1,,在每个水冷壁管1中心线上垂直焊有一条钢条3,所述的钢条3为羽翼形。
