Description

Ash removal channel of coal economizer

Technical Field

The utility model relates to the field of economizers, in particular to an ash removal channel of an economizer.

Background

The economizer is a device which is arranged at the lower part of a tail flue of a boiler and is used for recovering the waste heat of discharged smoke, and because the device absorbs the heat of high-temperature smoke, the temperature of discharged smoke of the smoke is reduced, the energy is saved, and the efficiency is improved, so the economizer is called as the economizer, and is mainly suitable for industry and is gradually popularized to agriculture and related industry business.

The economizer mainly absorbs heat carried in flue gas, reduces the temperature of discharged flue gas, reduces the loss of discharged flue gas, saves fuel, reduces the heat absorption of the feed water on a heating surface because the feed water is heated in the economizer before entering the steam drum, can replace part of evaporation heating surface with higher cost by the economizer, improves the temperature of the feed water, reduces the wall temperature difference when entering the steam drum, correspondingly reduces the thermal stress, and prolongs the service life of the steam drum.

However, when the existing economizer is used, ash removal is not facilitated in the economizer, a large amount of dust can be carried by flue gas entering the economizer, after the economizer is used for a long time, the dust in the flue gas can be adhered and remained in the economizer, the effect and efficiency of the economizer on absorbing heat in the flue gas can be affected by the adhesion of the dust in the economizer, and the use of the economizer is not facilitated.

Therefore, we propose an economizer ash removal channel.
