What advantages does a CLM direct-fired tumble dryer have in terms of energy consumption compared with ordinary steam dryers? Let’s do the math together.
We set the comparative analysis in the condition of a daily capacity of the hotel linen washing plant of 3000 sets, and similar linen material and moisture content.
❑ The basic data on CLM direct-fired tumble dryers is as follows.
1. Dry 120 kg of towels per batch
2. The gas consumption for drying 120 kg of towels is 7m³
3. The gas consumption for drying 1 kg of towels is 7m³÷120kg=0.058m³
❑ The basic data on ordinary dryers is as follows:
1. The steam consumption for drying 50 kg of towels is 110kg.
2. The steam consumption for drying 1 kg of towel is 110kg÷50kg=2.2kg
❑ The basic data on linen is as follows:
1. The weight of a set of linen is 3.5 kg.
2. The proportion of towels is 40%.
3. The weight of towels be dried every day is about: 3000 sets × 3.5 kg × 40% = 4200kg/day
❑ Comparison of energy consumption and expenditure of different drying equipment for washing 3000 sets of hotel linen per day
● Daily gas consumption: 0.058m³/kg × 4200kg=243.60m³
The average unit price of gas in China: 4 RMB/m³
Daily gas expenses: 4RMB/m³× 243.60m³=974.4 RMB
● Daily steam consumption: 2.2kg/kg × 4200kg=9240kg
The average unit price of steam in China: 260 RMB/ton
Daily steam expenses: 260RMB/ton × 9.24 tons =2402.4 RMB
The use of a direct-fired tumble dryer rather than an ordinary steam dryer saves 1428 RMB per day. The monthly savings are 1428 × 30=42840 RMB
From the above calculation, we know that using CLM direct-fired tumble dryers can save 42840 RMB every month in China. You can also calculate the difference in towel drying costs between CLM direct-fire tumble dryers and regular dryers based on local steam and gas prices.
