The TecEco Tec-Kiln
The Tec-Kiln was originally designed for low temperature (<750ºC) calcination of magnesium carbonate to produce reactive magnesia[1] for use in TecEco Cements without releases and will be used in Gaia Engineering which is a process that contemplates obtaining the magnesium carbonates required from sea water to create man made carbonate for building and construction. The Tec-Kiln can also be used to produce reactive magnesia from other sources such as mined magnesite.
To reverse the environmentally damaging impact of molecular flows from techno-processes such as too much CO2 in the air, the TecEco Tec-Kiln will use non fossil fuel energy such as solar or solar derived energy (e.g. wind or wave energy) for producing the magnesia required for TecEco cements. It is unique in that it operates in a closed system whereby the waste energy from grinding is captured and there are no releases to the atmosphere.
In the simplistic representation of the magnesium thermodynamic cycle shown below the TecEco kiln provides de carbonation of MgCO3.
The Tec-Kiln is distinguished from existing kilns in that it grinds and calcines simultaneously in a closed system, making use of the heat generated by grinding to reduce the energy required for calcination[2]. The low temperature requirements and design of the Tec-Kiln make it easier to operate using non-fossil-fuel energy, such as solar power.
The TecEco Tec-Kiln is unfortunately somewhat secret due to patent matters. It is however an essential part of TecEco's grand plan to sequester massive amounts of CO2 as man made carbonate in the built environment using magnesium compounds.
Summary
The Tec-Kiln has the following features:
- Can be powered by various non fossil sources of energy such as intermittent solar or wind energy.
- Grinds and calcines at the same time thereby running 25% to 30% more efficiently.
- Captures CO2 for bottling and re-use for the production of man made carbonate in the Gaia Engineering process.
- The products – CaO and/or MgO can be used to sequester more CO2 and then be re-calcined. This cycle can then be repeated in a capture cycle.
