Assuming that the 10 ton/hour gas hot water boiler costs 500,000 RMB when purchased, the annual depreciation of the boiler is: 500000-(500000*5%)/10 = 497500 RMB.
Assuming the residual rate is set at 5%, and it is expected to use 10 years, then the annual depreciation rate of 10 tons/hour industrial gas boiler = (1-5%)/10*100% = 9.5%.
The monthly depreciation rate of the 10 ton/hour gas hot water boiler is 9.5% ÷ 12 = 0.79%.
The monthly depreciation of the 10 ton / hour gas hot water boiler = 0.79% * 500000 = 3950 RMB= 571.5US dollars.
