Air quality and burning wood or solid fuel, some information

The following has been lifted from a statement by Bruce Allen the HETAS Cheif Executive.


The Government’s main concern is Air Quality. The basic statement is that burning the right fuel in the right appliance reduces environmental impact from particulate emissions. Looking at the fuel, we must be clear that reducing environmental impact from mineral fuels means burning only smokeless fuels. The HETAS Guide and website lists many varieties. On the wood-fuel side the Woodsure Ready to Burn scheme is there to give a recognisable logo and brand to clean wood fuels that have a moisture content of up to 20% – use of which has been shown by scientific studies at Leeds and Manchester Universities to reduce particulates and in some cases by up to 80% over the use of poor quality fuel in open fires. By buying the right Ready to Burn fuel, and by installing Defra exempt and Ecodesign Ready appliances, they can be part of the solution rather than part of the problem.


The following is from HETAS technical bulletin number 9, interestingly it shows that when burning wood a small amount of moisture is of benefit and appliances are designed to operate with wood between 12 and 20 percent. This moderates the combustion process and puts the right amount of heat in the room. Wood that is to dry burns ferociously and drags in excessive volumes of air which cools flue gases and increases particulates. You must not slumber the appliance and burning good fuel keeps the liner in good condition. I have seen this so many times myself.
