Huadian Xinjiang Hami Branch: invited "foreign experts" for the boiler coking "visiting"

On September 9th, Huadian Xinjiang Hami Branch invited two American “foreign experts” to “consult” the boiler for coking. In 2009, since the boilers were designed using small kiln coal instead of boilers, the boilers exhibited various degrees of coking and high “drainage” in the exhaust gas temperature. The company had used artificially assisted cleaning and optimized operation and other measures have not completely resolved coking At the beginning of this year, the company adopted the “coking and spraying of boiler heating surface pipes” as a key technical transformation project and started implementation at the beginning of September. The project leader, Ma Jihui, said that the project uses a desulphurization retrofit project #5 furnace. The opportunity to stop the furnace will be carried out. It is estimated that the investment will be 500,000 yuan in 4 days. After coating, the heat absorption rate will increase by 3-5%.

It is reported that this project is represented by Huadian Guangyao, which adopts non-metal high-temperature coating technology from OXISTOP of the United States. The product is high-temperature resistant, wear-resistant, anti-corrosion, does not affect and enhance emissivity, and the coated surface coke block is very low-weight and is automatically dropped off. The characteristics of the furnace can significantly ease coking in the furnace during operation, improve the heat exchange efficiency, and do not form coke-forming bodies, thereby reducing the temperature of the flue gas, achieving safe production, improving efficiency, and reducing material consumption.
