Abstract

一种锅炉节能装置，由炉体、排烟道、空气换热器组成，所述炉体内设有燃烧室，燃烧室的一侧设有排烟道，排烟道上部与燃烧室联通，排烟道底部与排烟管联通，排烟管设有引风机，所述排烟道中间设有空气换热器，所述空气换热器进气端通过风机管与鼓风机连接，所述空气换热器出气端通过热风出口管与燃烧室联通。有益效果：设计简单，效果显著，即在锅炉排烟道内增加一个空气换热器，利用排烟道内排出的150-180℃高温废气，预热鼓风机吹入锅炉的冷空气的温度，能使冷空气预热到120℃以上的高温，提高了煤炭燃烧性，同时减轻引风机负载，减少耗电量。

Description

一种锅炉节能装置
技术领域
本实用新型涉及一种锅炉节能装置。
背景技术
燃煤锅炉在冬季生产期间室外温度一般在10℃以下，特别是深冬季节室外温度更是低于0℃，鼓风机吹入锅炉的冷空气由于温度太低，会降低炉膛温度，影响煤的燃烧，热量损耗增大，增加了燃料成本；而锅炉烟道排出的烟尘温度高达150-180℃，没有加以利用而白白排走，进一步增加了燃料的浪费。
发明内容
本实用新型的目的是针对现有技术存在的问题，提供一种能加热鼓风机吹入炉膛冷空气温度的锅炉节能装置，
本实用新型采用的技术方案是： 一种锅炉节能装置，由炉体、排烟道、空气换热器组成，所述炉体内设有燃烧室，燃烧室的一侧设有排烟道，排烟道上部与燃烧室联通，排烟道底部与排烟管联通，排烟管设有引风机，所述排烟道中间设有空气换热器，所述空气换热器进气端通过风机管与鼓风机连接，所述空气换热器出气端通过热风出口管与燃烧室联通。
本实用新型有益效果：设计简单，效果显著，即在锅炉排烟道内增加一个空气换热器，利用排烟道内排出的150-180℃高温废气，预热鼓风机吹入锅炉的冷空气的温度，能使冷空气预热到120℃以上的高温，提高了煤炭燃烧性，同时减轻引风机负载，减少耗电量。
附图说明
下面结合附图和具体实施方式对本实用新型做进一步说明。
附图为本实用新型结构示意图。
图中：1炉体，2燃烧室，3排烟道，4风机管，5空气换热器，6鼓风机，7热风出口管，8排烟管，9引风机。
具体实施方式
如图所示的一种锅炉节能装置，由炉体1、排烟道3、空气换热器5组成，所述炉体1内设有燃烧室2，燃烧室2的一侧设有排烟道3，排烟道3上部与燃烧室2联通，排烟道3底部与排烟管8联通，排烟管8设有引风机9，排烟道3中间设有空气换热器5，空气换热器5进气端通过风机管4与鼓风机6连接，空气换热器5出气端通过热风出口管7与燃烧室2联通。
