What if there was condensation in the chimney flue and how he get rid of it

click fraud protection

This phenomenon is observed quite often, even when everything seems to be designed and installed correctly.Especially the appearance of condensation in the chimney is that it does not consist of mere conventional water droplets.The resulting liquid contains many impurities, including, and resin.

by condensation - resin Gradually, they come in a variety of reactions, which are obtained as a result of a completely new chemical / compound adhering to the internal cavities of pipes.Many of the substances (eg acids) are harmful to the chimney.

Pipes for flue gas exhaust are different both in size, configuration, and material production - "galvanized" furanfleks (plastic version), brick, asbestos-cement.It is therefore advisable to consider the most important points relating to all the chimneys.The reader will understand and that the results of this information will be useful to correct problems with condensation in the chimney in relation to the gas exhaust system, mounted in his home.

consequences of condensation in the pipes

  • destruction of the channel material.It is mainly characteristic of the pipes, the inner cavity of which roughness is different (brick, asbestos).
  • gradual decrease traction.This is quite natural, because of the formation of "build-up" on the inside of the pipe diameter of conditional pass decreases with time.

Causes of condensation in the chimney flue

Without knowing it can not correctly identify the most effective way to combat this phenomenon.

  • wrong choice chimney scheme.This often happens when the design is done on their own, only on the recommendations of "knowledgeable" people.
  • Low temperature of combustion products (less than 100 ° C).
  • Insufficient chimney draft.
  • large temperature difference values ​​(indoors and outdoors).
  • Contact precipitation in the channel (for example, in the absence of the cap, vent or other security, assistive devices).
  • use fuel with a high moisture content, its incomplete combustion.
  • Irregular cleaning of the chimney.As a consequence - the excessive channel blockage.
  • Mechanical damage the chimney.
  • design and installation errors.
  • systematic exploitation of the boiler in the power saving mode (when its output temperature of a small set).

methods of getting rid of condensation in the chimney

k- 1 Using trap

This device solves the problem quite effectively.In his body (or separately) have a special compartment for the condensate collection.Setting trap simplifies maintenance of the chimney, which is practically reduced only to timely clean up drive.

unit price - from 786 rubles.

Warming chimney channel (especially in the upper part)

In this case, the effect of temperature fluctuations will be minimized, as the dew point will shift.

preliminary drying "fuel»

This applies to solid fuel boilers working with wood, briquettes, coal and so on.First of all it is necessary to pay attention to the order of their warehousing and storage conditions.

assembly

correct choice of fuel

firewood softwood contain large amounts of resin.Use them for the heating system to the chimney complex configuration or a large extent is not recommended, as the risk of various deposits on the inner walls of the channel is increased many times over.For more information about all sorts of wood here.

k- 2 Aging

installation scheme chimney should mainly consist of vertically oriented segments.Any deviations on the road, benches, and so on - the cause of the deposits as a result of condensation.The same applies to the immutability of the cross section of pipes throughout the length of the chimney.

Complete sealing of the channel, eliminating the slightest "leak."This requirement increases the traction and minimizes condensation.

temperature combustion

artificial increase in the temperature of the combustion products at the output of the chimney.This technique is used less frequently, but gives a certain result.One of the options - spec / channel setting (for example, insertion of "stainless steel") or replacement with a coaxial flue.

Compliance periodicity pipe cleaning soot

Timely removal of support at the level of traction and reduces the amount of condensation.
