Case A Danish Company was established in October 2002.The company has 600 employees and develops, produces and sells chewing gum. 1. meeting with the chief of maintenance, mecanical engineer and electrician in may Screening, just the week after the meeting. Catalogue of ideas: a. Optimizing of centralheat- and steamboilers (Boilerplant) b. Natural cooling c. Optimizing of compressed air system.

A. Optimzing of boilerplant The Company has installed 3 steamboilers, with a total effect on 10,2 tons steam pr. hour with 7 bar pressure, and an energyconsumption at about m3 N-gas i Furthermore there is installed 3 central-heatboilers with a total effect on Mcal/h, and a set-punkt at 90 gC, and an energyconsumption at about m3 N-gas i Suggestion: To establish fluegascooling at all the boilers To establish weathercompensation at the part of the central heat system which does not supply the dehumiditysystem in the processventilation To move the endusers, which needs a high flow temperatur in the central heat system to the steam system. Adjusting the central heat system to get a better cooling of the recirculation water To reduce stand by loss in the boiler central Possibly change 1-2 boilers.

A. Optimzing of boilerplant The Energyproject: The Company said GO to investigate the boilerplant. First we investigate the endusers to make them energyeffective before we investigate the boilerplant. Flowmeasuring at the distribution system. Where is the worst enduser when it comes to cool the water? How much flow and the temperature differences? Analyzing possibilities! Calculation / measuring on condensing operation New boilers or existing boilers, which cant bee let cold (turned of) Estimate a new recirculation string to the boilerplant to seperate cold and hot recirculated water.

A. Optimizing the boilerplant

A. Optimzing of boilerplant The result: The Company has chosen to invest in the project Installation of fluegas exchanger on steam boilers, which is cooled with central heat water. Moving consumption from the centralsystem to the steam system, because of 2 processes which needs high flow temperature. Connect the boilers in tandem (Traditionel cascadeconnection), so the operating boilers is 100% loaded before the next boiler gets loaded. Earlier the total boilerplant was warm. Means less heat of radiation. Changing 3 centralheat boilers to new condensing boilers, which also means less heat of radiation.

A. Optimzing the boilerplant Saving potential: Flue gas cooling (condensing operation): m3/N-gas / year Weathercompensation in the central heat system, adjusting and moving endusers m3/ N-gas / year Change boilers m3/ N-gas / year Summary m3 / N-gas / year Value of the saving: Euro/year The total investment: Euro Simply pay back time 2.8 years The project is almost implemented and the savings seems to be even higher. Summer/ fall 2007

C. Optimizing of compressed air system The Company has installed 5 compressor for compressed air, with a total effect on 405 kW, the one cpompressor has broken down and needs to be changed. The application produces compressed air at about 7,5 bar. Operationtime hours/år Suggestion: One of the companys hughes endusers of compressed air is emptying trucks. One truck use approximatily 10 m3 compressed air/min with 0,8 – 1,2 bar, which means that the pressure in the mainsystem is throttled down from 7,5 to 1,2 bar. There also is a demand of very dry air. When they empty the trucks the pressure in the very end of the main system drops to 3 bar, which also is the absolute lowest accepted pressure in the main system. Establish a seperate compressed air system to empty trucks with a pressure of 1 bar. Reduce the pressure in the main system

C. Optimizing the compressed air system

Energy project: Measuring the application Analyzing the controlsystem Analyzing the needs Calculation on heat exchange potential Result: Change the hole application, 2 old compressors will stay for stand by Frequence regulating, which means no stand by loss. Lower the pressure in the main system, Dry air means better operation in the packing department Establishing heat exchange to the central heating system (saves m3 gas)

C. Optimizing the compressed air system Savings: Electricity save new applicaion kWh/year Electricity save lower pressure 0,6 bar kWh/year Heat Savings exchange m3 / N-gas Reduced supply cost Euro/year Summary Euro / år Invesment ,00 Euro Simply pay back time1,7 year Is implemented summer 2006

C. Optimizing the compressed air system

Energyproject Natural cooling The natural cooling project has never started, probably because of the investment and not enough savings. A large ventilation project has started and is implemented. The savings is kWh/year.

Case Grundfos A/S, Denmark Grundfos is one of the largest pumpindustries in the world. They produce more than 16 mio. pumps a year. They produce centrifugal pumps, and sells to more than 50% of the world market for these. Approximately 3500 employees in DK

Ventilation project at Grundfos Bjerringbro We have measured and calculated about 70 aggregates Total energycomsumption at ventilation approximately kWh/year 60 aggreates have a simply pay back time less than 4 years We have only optimated the ventilator and motor The amount of air ventilated is the same before and after the rebuilding.
