It is totally important that each one the combustion response (burning from the gas) takes position during the environment with the burning zone. Impingement of partially burned gasoline upon the feed bed or kiln wall needs to be avoided all of the time whenever a kiln is staying fired with coal or oil. Impingement of unburned gasoline particles around the wall and feed mattress is don't just dangerous on the refractory and clinker but also acts as a bad influence on fuel efficiency and kiln operating security. Alignment with the burner, fineness from the coal, along with the velocity with which the fuel and the principal air enter the kiln are the most important elements governing impingement.
It is a great apply to depart the pilot burner On this position right up until the kiln inside has acquired the required warmth to sustain constant ignition. Operator jargon typically refers to this as enough time when the wall temperature inside the burning zone can support the flame.
