A high-tech bonfire

A company planning to build an incinerator a wood-burning energy generator at Park Grounds Farm near Wootton Bassett would like people to believe it is something better than an incinerator. According to Mr Overfield, the chief executive of Purepower Holdings, it’s much more high-tech than that.

This is certainly not an incinerator. An incinerator is basically a glorified bonfire, whereas this is a piece of advanced technology that can transform the wood brought to the site into enough energy to power 5,000 homes.

So in what way is this different from an incinerator. Again, according to Mr Overfield, it’s advanced!

This is advanced conversion technology, which basically sees the wood heated up to 1,000 degrees. The wood becomes a gas and we put that gas into an engine that uses that as a fuel to power generators.

Hmm…. Perhaps Mr Overfield should have a word with the people at SITA UK ltd who know a thing or two about incinerators, having plans of their own for ‘Energy-from-Waste’ facilities. Here’s the SITA description of their process.

Inside the furnace, a series of grate bars move the waste through the furnace where it is dried and burned at temperatures of around 1000 °C. Burning waste in the furnace creates 2 different materials:

  • Hot flue gas – which is then used to create energy. This is known as renewable energy.
  • Incinerator Bottom Ash – which can be used in construction.

That’s an incinerator producing gas at 1000 °C, unlike Purepower’s ‘Advanced Conversion Technology’, which is something-too-high-tech-to-be-called-an-incinerator creating gas at 1000 °C. If you’re not convinced that this is an incinerator, look at what the equipment supplier at Purepower’s other bonfire power plant project manufacture: furnaces.

incinerator noun a furnace for burning rubbish

I suspect that to Mr Overfield, something that looks like a duck, quacks like a duck and waddles like a duck, is not a duck but an advanced amphibious aeronautic organism.
