Gas Engine CHP• Sizes from 100 kWe – 4 MWeSizes from 100 kWe 4 MWe• Heat from engine cooling water (≈ 90°C) + heat from hot exhaust gases (≈ 400°C) harnessedharnessed• Heat/Power Ratio ≈ 1.1/1

Uses for heat:• Water @ up to 90°C for space heating or

hot water demandhot water demand• Steam for Industrial Process• Exhaust gas CO2 generation• Absorption Chilling• Low temperature demand, i.e. for under-

floor heating, swimming pool etc.

Biomass CHPBiomass CHP is the use of a biomass fuel to simultaneously generate both

electricity and useful heat in a renewable processelectricity and useful heat in a renewable process


Biomass CHPBiomass CHP• CES Energy offers biomass CHP solutions for large

ind t i l iteindustrial sites

• Biomass fuel can be woodchip from forestry or energy crops (miscanthus willow etc)crops (miscanthus, willow etc)

• System electrical outputs from 500 kWe – 5 MWe

• Full heat recovery giving hot water/steam

• Heat:Power ratio > 3:1

• CES Energy has established relationships with industry leading suppliers worldwide

• Biomass CHP solutions offer ‘zero carbon’ alternative to conventional fuels (gas/oil etc)


h TWhat is Tri-generation?• Tri-generation is the simultaneous generation of the 3 primary energy

requirements for a building from a single fuel input.

• Electricity• Heat• Cooling

• This plant consists of these primary components:

l• CHP plant• Absorption chiller• Distribution system

l• Control system• Heat dissipation equipment

Dry CoolersDry CoolersThe same effect of the Free Cooling Chillers can be achieved on existing installations by installing a Dry cooler in parallel with the chillera Dry cooler in parallel with the chillerThe dry coolers work on the same principal of cooling the return fluid temperature to the flow cooling the return fluid temperature to the flow temperature or as close to it as possibleA bypass valve allows the fluid to flow directly A bypass valve allows the fluid to flow directly into the chiller when the ambient temperature will not aid coolingThe plant will however take up space which may not be available
