Where is the preheating module of Jiangling Baodian?

1, the position of preheater should be lower than the minimum level of engine coolant, and the inlet of preheater should be lower than the outlet of engine;

2. The inlet and outlet hoses should be as short as possible;

3. The inlet pipe and outlet pipe should not be excessively bent;

4. Pay attention to the air in the exhaust system;

5. After electrifying, pay attention to the temperature changes of the preheater and outlet hose at any time;

6. After a period of time, the inlet and outlet pipes should be hot (the inlet temperature is slightly lower);

7. Completely drain the engine coolant before installation;

8. After the coolant is re-injected, start the engine for about ten minutes to completely eliminate the air.

Extended data:

It is mainly the influence of ultra-high temperature on the system, and the crust blockage is mostly related to the high fever of the system. For the low melting point minerals in the preheater, the liquid phase can generally appear at 650℃ ~ 800℃. When the system temperature exceeds 900℃, more liquid phase has appeared in the system, and the probability of blockage increases immediately.

There are many factors that cause this phenomenon, most of which are because it is difficult to control the amount of pulverized coal in kiln head and/or calciner, and even the phenomenon of coal running; The raw materials entering the kiln are unstable, even broken materials, and failure to withdraw coal in time will also lead to high burning;

Especially in the early stage of heating and feeding, the coal quantity is generally too large, and air and coal should be added before feeding. Once the feeding fails to keep up in time, it will inevitably lead to the system burning, and may also lead to a long flame after burning, so the early feeding becomes a dangerous period of preheater blockage.
