Operating cost of a biomass fired steam boilers of 20 mwt:

1. Fuel cost: According to a 20-ton biomass steam boiler, 2700 kg of pellets are burned per hour, and the pellets are calculated at 1,200 yuan / ton. Fuel cost per hour is 1200×2.7 = 3240 yuan. It costs 10 × 3240 = 32400 yuan for 10 hours per day. Calculate 25920 yuan / day based on 80% of steam volume. It costs 25920 × 300 = 7776000 yuan per year for 300 days.

2. Motor power consumption: 29.5KW of drum, induced draft fan, 10KW in total of reducer, feeding machine, water pump and conveyor are calculated as 50KW. Calculated at 1 yuan per degree. The cost of electricity per hour is 50 × 1 = 50 yuan. 50 × 10 = 500 yuan for 10 hours per day. It is calculated as 500 × 300 = 120,000 yuan per 300 days per year.

3. Labor cost: one person per class, divided into 2 classes. RMB 2,000 per person per month. It takes 2 × 2000 × 12 = 58000 yuan per year.

4. Boiler repair and maintenance costs: Calculated at around 5,000 yuan per year for the first 3 years.
