I have a question regarding the ignition of Lurgi furnaces
Thread Content
Is the ignition principle of the Luchie furnace simply that: when the steam temperature rises to the ignition point of the coal, it catches fire automatically when air is supplied? Is it only related to the ignition point?
The most important thing is to reach the desired temperature of the steam. How do you know when it has reached its ignition point? It is determined by the outlet temperature, and it takes some time to achieve this
For steam at high temperatures, once the temperature at the outlet of the vaporizer exceeds 100 degrees, it is necessary to raise the temperature by another three hours or more before air ignition can be carried out
This is based on experience; for driving in cold conditions, a preheating time of about 3 hours is generally sufficient
It is necessary to include coal gas components in the sample gas, as the ignition points of different types of coal vary.
It is related to the ignition point of coal, but the heating time required for Ruhchi gasification is not only intended to ignite the fire; it is also related to the temperature rise of the equipment. It is mainly reflected in synchronized temperature rise of the furnace body, with the temperature rise per hour not exceeding 35 degrees Celsius. To prevent defects in the mother.
