ASK FOR AN ESTIMATE FOR FIREWOOD
IBS take care of the trading and marketing of FIREWOOD in bulk, through the direct contact with reliable producers of high amounts for domestic consumption or export, with producer businesses recognised and certified by organisations which certificate the product quality and the producing capacity.
We would like to come into contact with PURCHASERS, WHOLESALERS, BUYERS and DISTRIBUTORS of firewood.
SOME INFORMATION ABOUT AVAILABLE FIREWOOD:
PLACE OF ORIGIN OF FIREWOOD : specially Ukraine, Moldova, Romania and Russia. However, other origins for firewood are possible.
TYPE OF WOOD : Different kinds of wood are possible, such as fir, walnut, chestnut, oak, birch, robinia, ash, poplar, etc.
TYPE OF CUT : Usually the standard cut is about 27-30 cm. However, if specific request should be present (for example 50 cm or 1 metre) they can be underlined at the moment of the request.
DAMPNESS % : THE TYPE OF WOOD COMING FROM Ukraine and Moldova is drier, the wood coming from Romania has usually a higher dampness % and consequently a lower calorific value.
TIMES OF DELIVERY OF THE GOODS : after confirmation of the order about 1,5- 2 days if the firewood comes from Romania, 2-3 days if it comes from Moldova, 7-8 days if the origin of the firewood is Ukrainian leaving from the port of Odessa.
TERMS OF DELIVERY AND LOGISTICS : DELIVERY AND TRANSPORT BY ROAD THROUGH LORRY/ ARTICULATED LORRY FROM Romania and Moldova, through ship from Ukraine. The cost through ship is always more economic of that through transport by road . Also the transport by train is possible. However, the costs are accounted for only if other terms of delivery aren’t possible and for high amounts.
MINIMUM QUANTITY : 1 twenty-foot container (with cellophane locking)
TERMS OF PAYMENT : For the first supply or the first trial containers or for spot supplies, the payment of the goods must occur after the lading of the firewood on the container ready for the delivery and provided with high-security padlocks. After a local check by our staff and after the payment through bank credit transfer, the goods will be sent. The goods are provided with insurance from the supplier. For constant supplies, after the first trial containers, the term of payment with LC (letter of credit) is available .
to ask for an OFFER indicating your data and the type of firewood of interest, the QUANTITY ( SPECIFYING IF IT IS A CONSTANT OR SPOT OFFER), the DESTINATION that is the PLACE OF DELIVERY of the GOODS, the kind of cut required, and if possible a RANGE OF PRICE or a PRICE above which the goods aren’t considered of interest.
We will contact you to provide you information and an estimate. Thank you for your kind attention!

INTRODUCTION ON WOOD
The value of the wood is strictly connected to its energy content. Under certain conditions, it can be a fuel and it produces thermal energy potentially retractable.There are several types of wood, with different mix and degree of dampness
UNIT OF MEASUREMENT OF THE FIREWOOD AND WOODFUELS VOLUME
CM or CUBIC METRE (full wood) m3; generally used for wood logs;
SM (stere meter) it is used for masses of wood fuels containing empty spaces whose dimensions depend on the size of each wood. The stere meter can be divided into:
STCM(stacked cubic meter): it consists of a pile of logs that measures 3 feet by 3 feet by 3 feet. It is generally used for for firewood arranged in logs well stacked. This unit of measurement takes into account both the wood and the empty spaces.
LCM (loose cubic metre). It is the equivalent of the wood amount contained in a 3 feet by 3 feet by 3 feet trunk, non-arranged wood. It is often used for firewood not stacked in logs. Apparently, it is as well a unit of measurement taking into account both the wood and the empty spaces between the wood.
TON (t) traditionally used as unit of measurement for weighed firewood. It is the equivalent of 1000 kilogrammes (kg) and 10 quintals.
VOLUME AND WEIGHT
Specific weight of some kinds of wood: OAK 1,1 t/cm, BEECH 1,05 t/cm, CHERRY 1 T/cm, ROBINIA 1,05 t/cm, HOMBEAM 1,05 t/cm
In case of relative dampness > 50%, we can consider the wood as damp wood.
WEIGHT CONVERSION – VOLUME FOR CUT CHOPPED WOOD to 50%, totally abstract schedule ( the weight of the volume varies depending on the dampness)
*For what concerns lcm the length of wood logs is about 40 cm; if the length was 30 cm the wood would settle decreasing in volume, so 1 lcm of wood chopped close-cut would weigh more.
CALORIFIC VALUE (CV) and ENERGY DENSITY (E)
- CALORIFIC VALUE: generally referred to the Lower Calorific Value, it corresponds to the thermal energy emanated during the entire burning of a material, depending on the unit of weight used, usually expressed in MJ/kg or kW/kg.
- ENERGY DENSITY: it is obtained by the quotient of energy content and the stearic volume. It is expressed in MJ/sm or kWh/ms.
What can affect or determine the energy content? The weight and the moisture content (%M) or dampness.
In effects, the wood material is not present in nature in the anhydrous state, but it always has a variable percentage of dampness, given that it is chemically subject to the water absorbency, also due to the macroporosity, the parenchymal constitution of the cells and the chemical and histological composition.
The dampness is expressed as water percentage, as anhydrous dry basis wt%, or as the water content on a wet basis (M%).
Obviously, the more the dampness degree increases, the more the calorific value of the firewood decreases, because part of the heat, which is engaged in the evaporation of the water contained in the wood, is not available for the thermal use required.
The water requires 2,44 MJ/kg to evaporate, which correspond to the waste heat. The are two different kinds of measurement of the heat produced, depending on the consideration of water in its liquid or gaseous state. In the case of water in a liquid state the reference is to HCV (higher calorific value), whether if we consider the gaseous state, and consequently the heat extracted to reach it, the reference is to LCV (lower calorific value).
There is a slight difference among the calorific values of the different types of wood, always referred to the same water content; however, the broad-leaved wood has a calorific value of 17,6 MJ/kg just below that of the conifers, which is 18,1 MJ/kg at anhydrous state.
The water content for damp wood can exceed 50%, while it falls to 20% after the weathering of the timber. This means an increase of the calorific value up to 80% in case of dry wood. The % of cinders, another typical component of the wood, generally lies between 0,2 and 0,50 %
SOME EXAMPLES OF TYPES OF WOOD AND THEIR CALORIFIC VALUES
(expressed in kWh/kg)
- beech: 4
- maple, elm, poplar, Robinia: 4,1
- oak, ash: 4,2
- larch: 4,3
- douglas fir, pine: 4,4
- fir, spruce: 4,5
ENERGY CONTENT AND UNITS OF MEASUREMENT
- International System: MJ/m3, MJ/Kg, MJ/sm, kWh/m3, kWh/kg, kWh/sm;
- other units of measurement: kcal/m3, kcal/kg, toe/m3, toe/t, Btu/m3, Btu/kg;
1 kWh= 860 Kcal= 3,6 MJ
1 MJ= 239 Kcal = 0,278 kWh
