The second phase of The Energy Revolution™ at a UK mill is underway with the installation of a bespoke waste heat boiler.
The highly efficient boiler has been designed & sized to specifically suit the 1.5MW combined heat and power genset. The waste heat from the genset (which is a by-product from the electrical generation process) is recovered by the boiler and used to increase the temperature of water to generate 963kg/hr of steam which is then fed into the sites 9 bar steam system for use in their food production processes.
The superior efficiency from the combination of the CHP and Waste Heat Boiler will replace a large proportion of the clients grid energy, providing them with a stable supply and protection from volatile energy markets whilst significantly lowering their CO2 emissions.

WHAT IS COMBINED HEAT & POWER (CHP)?
A Chp is essentially an electricity generator, as it generates power, it produces heat which is a natural by-product of the generation process. This electricity is fed directly into an organisations property whilst the heat is harnessed within their wet hot water systems, or conversely by way of an absorption chiller utilised within refrigeration or air conditioning systems. In this instance the waste heat is recovered and used to generate steam for the sites food production processes.
In comparison with grid energy (inc. nuclear, hydro, wind and solar) which is up to 66% inefficient due to losses in generation, transmission and distribution, cogeneration Chp’s are located on-site, so these losses are virtually non-existent and G-GEN™ Chp’s run with approximately 99% efficiency.
The UK is producing ‘Green Gas’ or biomethane gas on an industrial scale and it is now an available option with new contracts from energy suppliers. Produced from “fresh” organic matter from landfills or biogas plants through anaerobic digestion, Green Gas is added to the existing natural gas network. Running a Chp on Green Gas produces zero-carbon power, equally as good as solar, but more consistently, more reliably and generates more power per square inch.
