Better atomization on the gasoline oil by growing the gasoline oil temperature and selecting a scaled-down burner orifice measurement (idea measurement), or utilizing a mechanical system inside the burner nozzle to deliver about much better atomization.
This has two consequences. To start with, strain will Establish up while in the kiln and warmth might be dispersed a lot more evenly. This allows to make a extra uniform temperature. Secondly, it lessens the amount of oxygen while in the kiln, making the reduction environment explained earlier.
Due to this, the recent air duct into the coal mill is provided with a safety ambient-air inlet system that enables, via a damper, tاe mixture of scorching with chilly air, and therefore controls the coal-mill temperature in just safe restrictions.
