Why should we have dry wood for burning?

Wood burning is a chemical process at which the heat is evolved. Each kind of wood has different chemical composition and dampness. That is why it burns differently and its fuel value is diverse.

Čtverec Wood dampness

Wood dampness influences its fuel value. That is why the wood that you use for your fireplace must be dried properly.

Damp wood has significantly lower fuel value as large amout of heat is consumed for evaporation ( wood under the bark between the core and bast can even include 75% of water).

Damp wood releases huge amout of smoke , tar and produces only few flames. It causes clogging of fireplace, pollution of heat- resistant glass and clogged chimney. When the stove is full of tar its efficiency and lifetime is rapidly reduced.

  • 1kg of damp wood ( dampness 40%) produces 8370 to 10467 kj/hour.
  • 1 kg of dry wood ( dampness 20%) produces 14650 to 16750 kJ/hour.
  • Ideální vlhkost dřeva pro topení v krbech a kamnech je do 20 %
  • Fresh wood usually has 50% dampness at average, dried wood in the forest 25-%30% and air-dried 10%-20%.

Čtverec General principles

  • Suitable wood for burning should be ideally dried up.
  • For quicker drying it is better to cut big logs to the small ones.
  • Wood should be stored in a covered, ventilated place prevented from rain.

... woodshed will not chop the woods instead of you but it will help you a lot in other ways.
