Optimization Technology for the Operation of Expanded Burning Bituminous Coal in FW Technology W-Flame Boiler
Faced with the challenge of reduced coal supply and power generation due to changes in coal supply in Guizhou province,guoneng Anshun Power Generation co.,ltd.has conducted a feasibility study on co firing bituminous coal for W-shaped flame drum boilers,aiming to seek solutions.during the research process,a series of technical measures were proposed to effectively control key issues such as spontaneous combustion,explosion prevention,coking,and damage to the arch burner caused by co firing bituminous coal.Blending bituminous coal not only reduces ammonia consumption and oil consumption,but also reduces coal consumption for power supply due to its high calorific value,thereby reducing coal costs.the low sulfur content of bituminous coal also helps to prevent high-temperature corrosion of the heating surface and prolong the service life of the equipment.The test results after co firing show that bituminous coal can meet the high load demand of the power grid,and the environmental indicators do not exceed the standard,confirming that its impact on the environment is controllable.
