How much coal is needed in a heating period in the North
1 kilograms of standard coal calorific value of 29 million 307 thousand joulesStandard coal: 648000/29307=22.11 kg, equivalent to 45 kilograms of ordinary coal.If the boiler efficiency is 50%, the amount of coal is 45*2=90 kg.
North such as Fushun, 1 square meters power of 50 watts, a heating period of 150 days,Total heat: 50*150 days *24 hours *3600 seconds =648000 kJ
The calorific value of coal is different, the thermal efficiency of the boiler is also different, it is difficult to calculate, can only be estimated according to the size of the boiler, the error is very large
