Heat recovery

Leading by example...​ Geothermal energy, PV solar panels, insulating materials Building produces 1.4 kWh energy per 1 kWh consumed Quantity of bio-sourced materials: 143 kg/m2 Ecocert, a French certification body for sustainable development, led by example when it decided to build an energy...

Comprehensive environmental gains Natural gas consumption reduced by 491 802 m3 per year Reduced electricity consumption by 1 030.4 MWh per year CO2 emissions down by 2 411.28 tonnes annually Following a comprehensive environmental review, a medium-sized grain processing company in Southeast Europe...

Comfort... hard to quantify but worth investing in Heat recovery saves money, improves working comfort in winter Resulted in annual savings of 218 MWh of heat (equivalent to over € 17 000) A company producing cables for electricity infrastructure located in the Czech Republic carried out a...

Excellent recovery! Recovering heat saves on energy and cuts CO2 Results in annual energy efficiency gains (~3.5 %) and less CO2 emissions (~600 000 kg) Carlsberg brewery is an energy-savings front-runner in line with its mission to optimise production and reduce overall CO2 emissions and energy...

Combined heat and power (CHP) helps to reduce total fossil fuel consumption from on-site boilers and the power stations they import electricity from. As such, CHP systems help to cut energy bills and the environmental footprint of a company. Recorded primary energy savings from CHP are around 18 %...

Recovering heat produced during the refrigeration process is possible and can help save energy and cut costs. Heat-recovery equipment can be fitted to existing plant or integrated in new buildings, and heat from the heat rejection stage of the refrigeration process can be recovered from the...

Pinch analysis spotlights energy-saving potential Connecting hot water circuits for internal and external saves around 35 000 MWh pa Using waste heat from upstream plants saves around ~241 000 MWh pa Wacker Chemie is an innovative global company with its origins in Germany, which produces silicone...

A princh of this and a good measure of that... Pinch analysis reveals where energy inefficiencies were costing the company One measure introduced cut steam use by 30 kW Up to 20 % energy savings were reached thanks to all measures implemented Pharmaceuticals are typically produced in recorded...

Flash steam released from hot condensate can be recovered and applied elsewhere in the plant to maximise overall efficiency. Recovery systems reduce steam-raising costs, utility bills and CO2 emissions, and help achieve significant savings in fuel, water and feed-water chemicals. The return on...

The return of the condensate Steam condensate is a well-known by-product of many industries. What is less well known is that it can be a powerful source of heat that can be reused. Using this end-of-pipe steam to improve efficiency makes economic and environmental sense. A plant’s energy load and...

Economisers are gas-to-water heat exchangers located within a purpose-built flue section. They are used to recover heat from flue gasses for shell and water-tube boilers. The main use of economisers is to pre-heat boiler feed water. An economiser can potentially be retro-fitted to most steam and...

On a daily or weekly basis, steam boilers blow down hot water from the boiler to avoid the formation of sludge. Blowdown heat systems can recover much of this waste heat and reuse it. The system is made up of a flash vessel and a heat exchanger. It works best when blowdown is carried out...
