Biomass - What should you consider?

When installing a Biomass heating system often some of the last things to be considered are actually the most important aspects of a Biomass system. This guide is designed to help you make informed decisions & help to make sure you have considered all aspects of installing a Biomass system before you make the decision to invest.

It is quite common for the decision to invest in a biomass boiler to be made, and the position of the boiler decided before considering the logistics of handling the fuel. This can lead to problems when the storage and delivery of the fuel is assessed.

1) Is there enough room for a lorry to tip & turn where the delivery needs to be made?

If the space is not adequate for a delivery to be made then the only solution is to move the delivery space, but this in itself can cause further issues. The decision will then need to be made as to whether you move the boiler along with the woodchip store or bunker, and then pipe the heat to where it needs to go, or do you move the bunker and transport the fuel to the boiler using a system of conveyors.

Not only should you consider the turning space of the lorry, but you should also carefully consider the position of the intake to ensure that the lorry can tip its goods without fear of the top of the trailer colliding with a wall or another object. 

2) When building your woodchip store or using an existing building, and allocating a required storage capacity have you considered the angle of repose of woodchip?

Angle of repose of woodchip
There is an angle of repose associated with woodchip because it does not flow well. This means that when a store is filled there is an angle of 45 degrees which the edge of the pile of woodchip makes and this reduces the storage capacity of a given space. The usable capacity of the store should also be considered, for example if the chip cannot be removed from the square corners of a bunker by the discharge system then these areas will fill up once and never empty. There are methods to improve the filling of woodchip stores including full length centre augers or levelling conveyors.

3) Will the system fit in with the area aesthetically?

Sometimes Biomass systems can be a little unsightly, but there are options available to help reduce the impact. For example Perry Biomass Engineering produces the BIO Bin. This galvanised steel woodchip storage bin can be clad in timber or box profile sheeting to blend in with its surroundings. 

4) Using delivery systems with blowers can be noisy, will this become a nuisance?

Perry fast auger intake
One particular client put a woodchip blower system in place that was producing about 120db of noise. During the early periods of operation local residents complained about the noise and dust generated during delivery. Eventually the client had to replace the system with a Perry Biomass handling BIO Intake which reduced the noise generated during the delivery to less than 60db.
