Start the burner, but it can't be ignited normally. Restart many times, and the ignition fails. What is the cause and how to solve it?

The main reasons are as follows

Cause of failure

here is too much air entering the furnace. Most of the reasons are the too large opening of the damper.

Solution

Reduce the opening of the burner damper and chimney damper, ignite the burner, and adjust the opening of the damper and damper to a proper angle after ignition.

Cause of failure

When the pressure of fuel oil is higher than that of atomized steam, ignition failure is easy to occur.

Solution

The problem can be solved by adjusting the fuel oil pressure to about 98kpa, which is lower than the pressure of atomized steam.

Cause of failure

Too low temperature or pressure of fuel oil causes ignition failure.

Solution

Increase the temperature or pressure of fuel oil.

Cause of failure

The fuel oil contains too much moisture, which causes difficulty or failure in ignition.

Solution

Dehydrate the fuel oil.

Cause of failure

Temperature or pressure of high pressure gas is too low.

Solution

Raise the temperature or pressure of gas.

Cause of failure

High pressure gas contains too much water.

Solution

Dehydrate elegant gas.

Cause of failure

Too much steam and too little fuel.

Solution

Turn down the steam valve and properly increase the fuel oil valve to achieve the proper oil steam ratio.
