How to prevent boiler coking, what are the hazards of boiler coking, and how to prevent it?

1.Choose a reasonable amount of oxygen for operation.

2.Select a reasonable furnace outlet temperature to optimize the combustion adjustment test of the boiler, and discharge smoke from the furnace.

The amount of oxygen is operated to ensure that the main parameters are qualified and the flue gas temperature of the furnace outlet is lower than the melting point of coal ash to ensure the vapor quality.

amount, thus preventing coking at the furnace outlet.

3 .Ensure a good mixture of air and fuel, avoid the formation of a reducing atmosphere near the water wall, and prevent.

Stop local serious ash accumulation and coking.

4.Various operating measures are applied to control the temperature in the furnace to be stable.

In order to solve the problem of coking in the boiler of the power plant, FM coal-fired additives can be used, which not only solves the coking problem, but also saves coal, reduces the exhaust gas temperature, and reduces the carbon content of the ash. It increases the efficiency of the boiler, reduces coal consumption and saves costs. It is a good product for energy saving, emission reduction and increasing coal source.

Removing the cost of FM additives will also bring considerable economic benefits to the enterprise. Contact: Mr. Wang.

1) The main hazards of boiler coking are: causing high steam temperature; disruption of the water cycle; Increased smoke exhaust loss; Reduce boiler output.

2) In order to prevent the coke of the car, the combustion should be reasonably adjusted in operation, so that the flame in the furnace is evenly distributed and the center of the flame is kept in an appropriate position; Eggplant ensures proper coverage of excess air to prevent anoxic combustion; When dirt and coking are found, they should be removed in time; Avoid running beyond force; improve the quality of maintenance; Ensure that the burner is installed correctly; The tightness of the boiler should be good, and the unreasonable place of the boiler equipment should be improved in time.

The phenomenon of boiler coking, the causes, and how to prevent it?

The phenomenon of boiler coking, the causes, and how to prevent it? The volume heat load of the furnace also depends on the arrangement of the water wall in the furnace. If there are too few water walls and the volumetric heat load of the furnace is too high, it will cause serious coking.

In particular, the slag trap pipe at the outlet of the furnace should not be arranged too closely, otherwise. Plugging air leaks. The air leakage of the furnace destroys the normal combustion conditions, resulting in the deterioration of the filling degree of the flame and the mixing of the stirring, and the rise or deflection of the flame center, which will accelerate the formation of coking.

The solution is to reduce the bright air volume of the old mu and make the furnace outlet negative. Coal should be mixed and burned. It is a good way to prevent coking and improve the thermal efficiency of the wide furnace by mixing and blending different coal types, reasonably grasping the particle size of coal and the fineness of pulverized coal, especially the bituminous coal with strong coking and poor coking ability.

Hope mine is helpful to you, thank you and have a great day!

There are usually three factors that affect the coking of the boiler furnace, one is the structural characteristics of the boiler, the second is the ash melting point and chemical composition of the coal type, and the third is the management of the boiler coal and the adjustment of the operating conditions.

According to the coking mechanism, coking is divided into high-temperature coking and low-medium temperature depressurization coking. High-temperature coking is due to the high temperature in operation, the burning of the bed material is abnormally violent, the temperature rises sharply, and high-temperature coking occurs when the temperature exceeds the melting temperature of the ash. Low temperature coking is because the fluidization is not good to make the local fire temperature, but the air volume at this time is enough to make the material burn rapidly, causing the temperature of the material to exceed the ash melting point, if not treated in time, coking will occur.

Therefore, coking is easy to occur when the temperature exceeds the melting point of ash. Coking can occur at both high and low temperatures. The use of coal with less ash is beneficial to prevent coking.

The main causes of boiler coking are as follows:1Insufficient combustion, combustion chamber temperature too low:

2.The combustion chamber is too hot, and the combustion chamber temperature is too high; 3.The fuel contains a large amount of dust in the bend; 4.

The amount of air entering the combustion chamber is insufficient: 5The flue gas emission of the combustion chamber is less than precession; 6.

The water level in the combustion chamber is too low.

Summary. Hello dear! Coking refers to the accumulation of impurities in the fuel on the inner wall of the boiler to form coke residue.

Coking can adversely affect the operation of the boiler, such as the following:1Blocked Pipes:

Coking causes the cross-section of the tubing to become smaller, increasing the resistance of the fluid. This affects the fluid's fluidity and heat transfer performance, resulting in a decrease in the efficiency of the boiler. 2.

Erosion of the pipe wall: Coking will increase the temperature of the pipe wall, resulting in oxidation and corrosion of the metal on the pipe wall, and shortening the service life of the boiler. 3.

Increased maintenance costs: Coking inside the boiler will increase the difficulty and expense of maintenance and cleaning, and prolong the downtime of the boiler for maintenance. 4.

Safety hazards: Coking may lead to pipeline explosion, ** and other safety accidents. Therefore, it is necessary to reduce coking inside the boiler as much as possible, carry out regular cleaning and inspection every year, use suitable fuels and additives, and control the temperature of the boiler wall and combustion process.

Hello, coking refers to the formation of a hard layer of material due to the accumulation of deposits or combustion products on the internal pipes or combustion chamber walls of the boiler. The impact of coking on the boiler is very unfavorable, mainly in the following aspects:1

Reduced thermal efficiency: Coking will lead to a decrease in the heat transfer efficiency of the boiler because the coking layer will hinder the transfer of heat, thus reducing the thermal efficiency of the boiler, which will lead to a waste of energy. 2.

Increased energy consumption: Since coking reduces the thermal efficiency of the boiler, in order to keep the boiler running properly, it is necessary to increase the consumption of fuel, which will lead to wasted energy and increased costs. 3.

Affect safety: Coking will cause the internal pressure of the boiler to rise, which will increase the risk of slippage of the boiler, which will pose a threat to the safety of personnel and equipment. 4.

Extended maintenance intervals: Coking can cause damage to the boiler's piping and combustion chamber walls, requiring more frequent maintenance and cleaning, which will increase boiler maintenance costs and downtime. Therefore, in order to avoid the adverse effects of coking on the boiler, the boiler needs to be cleaned and maintained regularly to maintain the normal operation and high efficiency of the boiler.
