Heating type gravity
WebCrude oil is classified as light, medium, or heavy according to its measured API gravity. Light crude oil has an API gravity higher than 31.1° (i.e., less than 870 kg/m 3) Medium oil has an API gravity between 22.3 and 31.1° (i.e., 870 to 920 kg/m 3) Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3) WebThis type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil. Inside a gas- or oil-fired …

WebHeat of combustion depends on the relative lignin and holocellulose and extractive contents of wood. Cellulose and hemicellulose have a higher heating value of 18.6 kJ kg -1, whereas lignin has a higher heating value of 23.2–25.6 kJ kg -1. Higher heating values of extractives are about 32–37 kJ kg -1.
