本文提出的线算图能根据燃料的低位发热值迅速地求出锅炉和燃烧炉的效率。这些燃料包括:煤、油、天燃气。燃烧10~6英热单位的燃料所需要的空气量可用下式表示: A=C(1+E/100)
The line graph proposed in this paper can quickly calculate the efficiency of the boiler and the combustion furnace according to the low calorific value of the fuel. These fuels include: coal, oil, natural gas. The amount of air required to burn 10 to 6 British thermal units of fuel can be expressed as follows: A = C (1 + E / 100)
