    Coal Slurry Gasifier Burner

    As the critical equipment of coal slurry gasifer, Coal Slurry Burner is to deliver the coal slurry and oxygen into the gasifier and organize the combustion reaction in high temperature so that the coal slurry and oxygen after complete reaction can produce desired syngas containing CO, H2 and etc, which becomes the raw material of more chemical products after further treatment. Gasfication burner is the beginning link of the entire production process and its performance is vital for the normal operation of long term stable operation of the entire production line.


    Working Principle: 

    The Coal Slurry Burner has 4 channels, with oxygen channel in the center and then coal slurry channel, outer oxygen channel and cooling water channel accordingly. The cooling water channel is divided into cooling water in & out channels to form a circulation at the burner head to improve the cooling process of burner head and prevent it from damages owing to high temperature.


    Before the burner starts operation, usually conventional burner is used to increase the reactor temperature to the desired value to ignite the coal slurry. The cooling water is supplied at the same time. Then coal slurry and oxygen is delivered into the high temperature reactor for reaction. When the burner is ignited, the reactor pressure is gradually increased to the value desired by gasification reaction. Now the burner starts normal operation.

    Compared with conventional 4-channel arrangement, the coal slurry burner developed by SMDERI has made major improvement to the cooling water structure. The cooling water channel combines water jacket with water coils. Water jacket is used at the end face to enhance the cooling to end face by forced cooling of whirls. In addition, the end face uses thin wall structure to improve the effective heat exchanger. A heat resistant coating is sprayed to the surface to greatly improve the resistance to high temperature.


    Flame arresting device is provided inside the water jacket to prevent backflow of hot flue gas. As the cooling water pressure is lower than the gasifer pressure, if the end face is burnt and damaged, hot flue is apt to flow back to the pipelines along the cooling water return line. In this case, if the monitoring system or valve does not act promptly, there might be explosion hazard. A flame arresting device is provided to effectively prevent hot flue gas backflow and create enough time for the system to react and thus prevent major hazard.


    The nozzle of burner is specially process with wear-resistant alloy coating to improve the wear resistance of coal slurry channel.


    With all these measures, the overall performance and service life of burner are greatly improved.



    1. Process calculation with FLUENT

    2. Special material of high crystal phase grade used for cooling channel at the burner head to resist high       temperature thermal stress;

    3. Special coating applied to extend the burner service life and improve the wear resistance;

    4. Mainly constructed with stainless steel and nickel-based alloy steel.
