Exhaust gas incinerator manufacturers: Analyze the common faults and causes of incinerators

There are often some failures in the operation of incinerators. Don't worry, the following is a summary of some failure causes of exhaust gas incinerator manufacturers for your reference.

Exhaust gas incinerator manufacturers to analyze the incinerator common faults and causes

The exhaust gas incinerator manufacturer believes that if the flame appears in the initial ignition and light oil combustion stage, it may be because the oil level of the diesel tank is too low, the diesel oil contains water, the valve of the diesel system is not opened normally, the ignition electrode is faulty, the light oil nozzle is abnormal, the photosensitive resistor is not clean, and the smoke exhaust baffle cannot operate automatically normally.

2. If the flue gas temperature is high (375°) or the furnace temperature is high (1200°), alarm and stop the furnace.

When burning solid waste, too much solid waste is filled. When burning dirty oil, the amount of dirty oil is too large. Reduce the pressure of dirty oil or the speed of the metering pump appropriately. The air inlet volume in the furnace is too small, the air inlet fan is abnormal or the air inlet is blocked. The exhaust baffle or fan is abnormal.

3. Bad atomization and combustion of dirty oil nozzle.

Carbon accumulation in the furnace is serious, which may be dirty oil nozzle, low oil pressure or insufficient atomized air.

4. The combustion chamber flame is unstable and the incinerator vibration is large.

The dirty oil injection is unstable, the carbon deposition in the exhaust flue is dirty and blocked, the smoke exhaust fan or baffle is abnormal, the air inlet in the furnace is blocked, and the dirty bearing in the wind blade is damaged.

What maintenance work should be done before incineration by the exhaust gas incinerator manufacturer?

Before incineration, the incinerator needs to be repaired, mainly as follows:

Clean the residual ash in the furnace and check the surface of the refractory brick inside the furnace. The air supply fan of the incinerator is located at the bottom of the incinerator and supplies air to the furnace through the four ports at the bottom of the furnace. Too much garbage filling and too much ash will block the air intake.

Disassembly and clean sewage pipe, metering pump outlet and fuel injector equipped with two pneumatic valve, pneumatic valve is opened by the control air, the valve spool sealing material is rubber, easy to deformation under high oil temperature, dirty oil cooling, the viscosity of the valve spool will increase, resulting in the valve spool opening is too small, or even can not be opened at all, waste in dirty oil is easy to be blocked here, therefore, The two pneumatic valves should be disassembled and checked before burning. The dirty oil nozzle is the same. Dirty oil and garbage can not be sprayed normally after blockage, and should be cleaned up before burning.

Stop the steam heating of dirty oil before incineration. When the steam of dirty oil cools to 80, start the dirty oil pump for full cycle. The high temperature of dirty oil is not conducive to the operation of auxiliary equipment such as dirty oil pump, metering pump and pneumatic valve.
