Wood pellet storage carbon monoxide.
There is growing use of wood pellet and wood chip boilers in the uk.
This report describes a study involving seven site visits to develop evidence to inform hse engagement with the industry on the prevention of carbon monoxide poisonings.
Carbon dioxide is what is put off from composting wood and what is in farm silos.
2002 in europe caused by carbon monoxide poisoning following entry into wood pellet storage areas.
The study found that.
In a recent case a carbon monoxide concentration of approximately 1 was measured in a sealed cargo hold of a ship containing wood pellets some 18 days after the cargo was loaded.
Although there have not been any incidents.
Carbon monoxide is a gas that comes from incomplete combustion of various fuels.
Emission rates for carbon monoxide from wood pellets of 100 885 mg ton day have been reported in the literature.
The oxygen concentration at this time was less than 1.
If you have carbon monoxide in your pellet storage area it s not your pellets.
Factors affecting the amount of carbon monoxide released from wood pellets.
Wood pellet derived carbon monoxide has been a cause of concern for indoor storage scenarios but research suggests it s an easy fix.
In conclusion it can be said that life threatening levels of carbon monoxide can arise from wood pellets kept in storerooms not only at high temperatures but also at average room temperature with a large headspace by freshly produced and or recently filled pellets and at the humidity usually found in these storerooms.
Wood pellets for boilers are normally stored in a large sealed hopper tank or a storage room that has a screw feeder auger connected to the boiler.
Knowledge of the hazards.
To raise awareness of the dangers associated with the storage of wood pellets.
Alternatively the hopper tank can be mounted over the boiler for gravity feeding.
