Best boiler for demolition wood chip

[westfield]

HI I'm looking for a boiler that can handle demolition wood chip as in non virgin I've got an endless supply of screened chip from our recycling business so are considering a boiler to heat 2 houses. Any info would be appreciated. Cheers

You would need to get it checked too see exactly what's in it if you want the RHI.

For just two houses it may not be worth it.

Is it chipped or can you produce it whole? I don't think you will find a chip boiler that can that, both legally and mechanically, however there may be a batch boiler that can if its in solid form.

Where are you based in the world?

We can help - inbox me for more details. We offer full contenerised solution for recycling plants, from 130kW up to 7MW, RHI approved allowing you to burn waste wood class A, B and C.

Try googling BGI biomass.

You need to speak to David Tomkinson at Tomkinson Heating Ltd/TW Power Ltd. They are in Stockport and have a huge amount of knowledge on biomass heating and chp and have multiple installations throughout the UK. They have recently announced that they have a chp which is certified to use waste wood to grade C and are renowned for the very high quality of there technology and installations.

Just make sure you have the right permits and tests done as local councils are tightening up on this type of fuel. RHI certificate is one thing that keeps OFGEM happy, local councils are a different story, particularly if close to a SSSI.

Quite, isn't Grade C wood a waste? And as such needs to be WID compliant? http://www.organics-recycling.org.uk/uploads/article2892/Wood Briefing_28Aug2014V1 final.pdf

That was my understanding which made me v surprised / impressed that a standard set up could burn this. If this is the case then the market for grade c waste is huge now - who will bother will virgin chip now?

To comply with the requirements of WID is very, very expensive from an emissions monitoring perspective. You'll also need a permit, which would fall under the 'installations' category. Unless there's a derogation I am unaware off?

That's my thoughts too - hence my surprise.

If folk can buy chip boilers under the RHI to burn grade c then surely the market for virgin chip boilers is here by over?

Whilst looking at a wide range of boilers I did not come across any with Grade C wood chip listed on the RHI cert, A1,A2,B1 and B2 were the most I saw on one certificate. What costs are involved in getting grade C passed for both the RHI and to be WID compliant?

It's important that +2 sec combustion residence time is met as well because EA is planning to make onsite testings for the residence time.

Here is the latest SWIP document regarding of that. This is important because I do believe that normal biomass grate firing boilers with backup burner do not meet these times if onsite testings required.

We decided to upgrade our solutions so that we can also burn 20% waste together with waste wood which reduces landfill costs.

Just a small point, SWIP is regulated by the Local Authorities as opposed to the EA. That is not to say that the same requirements do not apply. Residence time is 2 seconds at 850oC for non-hazardous wastes and 1000oC for hazardous waste.

Thanks,
I had a discussion with EA and they told that they are working on this issues because they made BAT document which shows clearly how + two sec 850 degree combustion residence time must be met and monitored. This document was part of my previous comment.

I met one plant owner and they had "WID-Boiler" and authorities came back and asked for evidence of combustion residence time as manufacturer warranty was not enough.

Exova Catalyst which is one of the UK leading testing laboratory will make onsite independent combustion residence time testings soon for them.

Also, part of proper waste combustion process our technology allows taking 20% waste stream as well which will reduce landfill costs.
