The wet end of the paper machine produces most of the heat and moist air leaks into the machine hall. Thus the wet end exhaust plays a key role as far as the machine hall air flow dimensioning is considered.
A high dewpoint closed dryer section hood is an essential part of a modern paper machine, but it can also greatly improve the dryer section efficiency of older paper machines.
TM Systems is very aware of the energy challenges and the pressure toward environment-friendly operations in different process industries. Therefore we have put extra effort to further develop energy saving solutions, including top of the line heat recovery systems. We deliver solutions that cut energy costs and enable more environmentally friendly production.
Case: Mondi Stambolijski Bulgaria: Trim handling system for a winder.
The customer’s trim conveying system was not efficient enough. The existing system was ejector-based. The winder was not able to run at full speed and the ejector air was blown to the pulper causing the area to become overpressurised. Additionally, the energy consumption was too high. [Read more…]
Many leaks and lost energy in the old systems, how could we improve them? What is the right solution to minimize the losses considering the weather conditions range from -45 °C to +35 °C? Heat recovery.
Heat Recovery System
Case: BillerudKorsnäs, Skärblacka: PM9 air system rebuild.
The BillerudKorsnäs Skärblacka PM9 machine hall ventilation system needed updating. The amount of supply air was insufficient. The air balance and working conditions needed a new supply air system and a heat recovery system.
The benefits of energy efficiency are manifold – lower energy bills, improved air quality, reduced greenhouse gases, increased energy security, and a deferred need to invest in new infrastructure.
A TM Systems case study shows that using the latest developments in energy efficiency in paper making can result in savings of up to 9 %.
