CTEC has developed a full turn-key localised residual waste advanced gasification system to recover heat to generate electricity and hot water with completely safe emissions to the atmosphere, cleaner than European standard limits. 

 

We recognise a huge disadvantage in the UK by not implementing network heating for industrial and domestic communities. This also applies to varying degrees to other countries.

 

How it works

In the case of plastic waste CTEC creates a burn ability with a mix of 75% plastic and 25% biomass for a perfect gasification process. This fuel is pushed onto the grate where high volumes of exhaust gas recirculation is used to slow the combustion process down, utilising 100% of the energy from the product. Superheated steam is created in a compact heat exchanger from the hot gas which is used to drive a modern day advanced steam turbine.

Hot flue gases pass through a cyclone removing fly ash before filtering through bag filters. The gas is then carefully re-circulated back into specific areas of the gasifier to promote ultra clean emissions. The gas finally passes though a pellet filter before entering the atmosphere. All emissions are continually monitored 24/7 to ensure conformance to rigorous European standards

The bag filter residue removed from the cleaning process is sent for recycling for further treatment. The bottom ash is conveyed into a storage container and used to make building blocks. 

This single system will produce 250kw of electricity and 2MW of thermal hot water. The electricity is connected  to the national grid, the thermal hot water can be used for a heating network or comfort cooling, and the remaining ash made into building materials .

The CTEC Green Power Network system is a combined heating and power product, designed to produce energy from residual waste, domestic/industrial, medical, sea & Land with high plastic/biomass.

 

One CTEC Green Power Network system utilises 500 kg/h of residual domestic or medical waste, this will supply approximately 264 houses with electricity and 783 houses for hot water or converted to cold water for cooling via absorption chillers.

 

The CTEC system can provide free energy for heating or cooling to businesses using their own waste keeping everyday costs down to a minimum.

Capturing exhaust heat energy and converting it to steam to drive electrical generation has been around for many years. The combination of modern day electronics, high speed steam turbine and a highly efficient robust heat exchanger allows for efficient local small scale power generation and for our customers to dispose of their waste materials at source.
