The Working Parameters of a Laundry Plant
Laundry configuration: A 60kg 16-chamber tunnel washer
Tunnel washer’s single linen cake discharge Time: 2 minutes/chamber (60 kg/chamber)
Working hours: 10 hours/day
Daily output: 18 tons/day
Towel drying proportion (40%): 7.2 tons/day
Drying Time of Tumble Dryer:
❑ 120 kg steam-heated tumble dryer: 30 minutes/time (Premise: The tumble dryer is highly efficient. )
❑ 120 kg direct-fired tumble dryer: 20 minutes/time
Unit price of steam: 280 RMB/ton
Unit price of gas: 4 RMB/cube
Steam-heated Tumble Dryer Configuration
5 sets of 120kg tumble dryers (1 set for dispersing, 4 sets for drying)
Steam Consumption
❑ Steam-heated tumble dryer consumes 140 kg of steam for drying 120 kg of towels.
❑ Drying 7.2 tons of towels consumes about 8.4 tons of steam.
Steam charge (days): 280 RMB/ton × 8.4 tons = 2352 RMB
Direct-fired tumble dryer configuration
4 sets of direct-fired heat-recovery tumble dryers (1 set for dispersing, 3 sets for drying)
Gas Consumption
❑ Gas consumption of a gas-heated tumble dryer drying 120 kg of towels: 7 cubic meters of gas
❑ Gas consumption for drying 7.2 tons of towels: 420 cubic meters of gas
Gas charge (days): 4 RMB/cube × 420 cube = 1680 RMB
Conclusion
Comparison of energy costs for drying towels using gas-heated dryers and steam-heated dryers for a tunnel washer system that processes 1.8 tons per day.
❑ Steam costs/ year: 2352RMB/day × 365=858480RMB
❑ Gas costs/ year: 1680RMB/day × 365=613200RMB
● Using a gas-heated dryer saves money annually compared to a steam-heated dryer:
858480－613200=245280RMB
The data comparison is based on the comparison between CLM steam-heated tunnel washer systems and direct-fired tunnel washer systems. Whether it is in terms of the dehydration rate of the water extraction press or energy saving and efficiency of CLM steam-heated tumble dryers, the CLM steam-heated tunnel washer systems are better than most other brands. If the equipment from these brands is compared, the gap will be even greater.
