Since the beginning of this year, the petrochemical branch of China and South Korea has actively carried out technological breakthroughs in tackling the long-term operational challenges of CFB boilers. At present, the operating cycles of the three boilers have all created the highest record in history.
The CFB boiler is the heart of the whole plant and the source of energy and power. The average boiler operating hours in 2014 ~ 2016 are 130 days, 160 days and 233 days respectively.
In order to further extend the boiler operating cycle, improve the reliability of the system and reduce the safety risk, the power sub-division optimized the coal management from the source and set up a coal-based management team at the company level to plan the production department, the material circulation department, the technical management department, the party Group Management, Power Division, laboratory personnel related to the formation of a coal management team, regular coal management seminars to optimize the work into the plant.
At the same time, they analyze the wear and tear of the boiler.According to the inspection during the inspection and the data analysis of the water wall tube thickness measurement to determine the main wear location, and to develop the corresponding measures, in the area of severe boiler wear coating wear-resistant alloy layer, Role, while the serious wear and tear, furnace wall thickness of less than 4mm area replaced with wear-resistant tube.
After technical research, No. 1 furnace safe operation reached 256 days this year, No. 2 furnace reached 274 days, No. 3 furnace reached 384 days to extend the boiler running time to create daily benefits of 500,000 yuan.
