What is the reason for the positive pressure operation of waste incinerator?

Domestic waste incinerator should keep negative pressure in the furnace, and positive pressure appears during operation. Refer to the following treatment.

The following reasons will cause the positive pressure problem of waste incinerator:

1, there are too many things to burn in the furnace, which is overloaded. 2. The induced draft fan stops running or there is something wrong with the induced draft fan system. 3. Too much fuel is added or the calorific value of combustible is too high. 4. Excessive dust accumulation in the furnace leads to smaller space in the furnace. 5. The pipeline is blocked.

When there is positive pressure in the garbage incinerator, the flue gas is easy to leak and the furnace temperature drops sharply. Before returning to normal operation, the boiler must be shut down to solve the above problems.
