5 Energy in laundries, 3 Energy saving possibilities
We now come to the saving possibilities. That is, there are a lot of possibilities to design a sustainable process. Module 3 chapter 4 handled two of them.
Which measures are differenciated for energy saving?
ecologic and economic
cheap and expensive
organizatorial, technical and technological
Please choose the correct order for application of measures!
technical, technological, organizatorial
ecologic, economic
organizatorial, technical, technological
Which kind of factors or processes do organizatorial measures influence?
chemistry, temperature, time (according to Sinner circle)
laundry detergents purchase
coordination of washing programs, cycles, machine load and steam consumption
How can steam generation be optimised?
process-data monitoring, optimal burner-adjustment, deaeration of heat exchangers, re-usage of condensate, isolation of steam pipes, installation free from leakages
no possibilities exist
only by installing new machines
Which kind of steam generation is most economical?
low-pressure steam
high-pressure steam
none of both, electrical and steam-heating will be more economical
Technical measures. Sinner`s circle. Which factors of Sinner circle do technical measures impact?
temperature and mechanics
chemistry and time
chemistry and mechanics
Heat flow volume Q is dependent of what?
liquor volume, max. temp of liquor, losses by radiation and duration of washing cycle
reverse rythm, chemistry
mechanics, time
Laundry processing. Name positions where energy recycling is possible.
waste water and waste heat
there are no possibilities of energy recycling
installation of new machines
How can the factor "temperature" be influenced?
substitution by higher mechanics, low temperature washing process, application of heat exchangers and thus heat recovery
factor temperature depends on textile
not at all
How can factor "mechanics" be increased?
form and dimensioning of paddles, reduction of liquor ratio, reverse rythm
