I have a traditional open fireplace, measuring 65cm wide, 57 high and 42 cm deep .. The height of the chimney approx is 5mts .. With south wind, impossible to turn it on, the smoke does not rise and there is no way to ignite it ... did I read what with a hole behind it could be solved ..? A hole behind the chimney that communicates with the outside, why have air and can burn well? Would it work? What measures would be? And where would the hole be? And would it be open? Could you tell me more precisely how to do it? But what other solution could it be? (The winds here are strong, there are usually daily winds of 20km and more too)

There are several types of caps so that air does not enter, one of them and very effective is the one that turns and aspirates the fumes, the greater the amount of wind the faster it rotates, aspirating the gases and fumes.

Cecilia: for a combustion box, regardless of whether it is a grill, bread oven, or, heating, to work well with respect to the suction of combustion gases, it requires that the section of the inlet mouth and that of the duct of the chimney, have a ratio of 1 to 0.3, that is, chimney conduit 1/3 of the mouth of the combustion box, in addition to a height of no more than 0.40m from the base of the chimney, must have a maze that makes that the descending column of the winds, they are redrawn upwards, they call it, lung, and, if at the exit to the four winds, there is a wall that acts as a screen that stops the winds, it will be necessary to put on a cap to help To suck the fumes. luck

I think the dimensions are fine, I only have one doubt ... when looking inside the chimney you can see the sky, is it normal?
and when it is off, a lot of air comes in, it looks like a window !!!! Is that normal too ???

That the sky is seen is abnormal, the lung that I mentioned is missing, the most common is a sheet inclined upwards (looking from below), which generally seals the entire channel, but that in the upper area, there is a widening of the canal , so that the fumes run through it as a labyrinth, and the descending winds collide and return upwards, no it is not, it is not a chimney, it is only a vertical pipe. luck

Hi. A client had a similar problem and solved it by wetting a large piece of cotton with common alcohol (does not smoke) and once "hot" the duct greatly improves convection. Before making modifications do the test. How did this happen? Did you always have the same problem? The closure or hat of the chimney greatly influences. regards

Dear, if there is a bordering wall near the chimney that exceeds in height the mouth of expulsion of the same one, that could be the problem, since the mouth has to be free to the FOUR winds to have a good circulation. The proposed alternative of cap or expire as they say here, it would be something valid that led to a higher consumption of logs by the forced circulation of air inside the chimney. regards

Good afternoon, there are no adjoining walls, since it is countryside, there is also no grove near the fireplace!

Hi A chimney has to have very precise measurements .

I hope the image serves I leave another link for you to see the constructive aspect and its measures https://martinbonari.com/5-problemas-constructivos-de-un-hogar-a-lena/ regards
