How does the heating energy consumption change when the raw material becomes heavier?
Thread Content
When the raw material becomes heavier, the load on the atmospheric pressure heating furnace decreases and gas consumption falls – why? As the raw material becomes heavier and the light components decrease, wouldn’t increasing the gas consumption to induce a phase change be necessary in order to maintain the original temperature? How could it be the opposite?
Can it be understood in this way that, when processing different raw materials, the outlet temperature of the atmospheric pressure furnace remains constant (for example, 360°C). As the density of the raw material increases, at the same temperature, fewer components can be vaporized, and the latent heat of vaporization decreases; as a result, the load on the atmospheric pressure furnace drops, and fuel consumption is reduced.
