A cluster of farm buildings has an annual requirement of 460 hours heating at 150 kW The farm owner wants to use a wood-fired boiler burning the wood chips harvested by the farm to supply the required heating to the farm buildings. The thermal efficiency of the boiler (based on low heating value) is known to be 79%. The fuel analysis of the wood chips is known as follows: C = 45.04 wt%, H = 4.76 wt%, O = 29.04wt%, N = 0.36 wt%, S = 0.12 wt%, Ash = 0.68 wt%, Moisture = 20.00 wt% (all on an as received basis). Calculate the required minimum quantity of the wood chips that needs to be harvested by the farm each year (in the unit of kg, as received) so that the farm can have sufficient wood chips to provide the required heating
