Causes and solutions for coking and ash accumulation of biomass burners

When using a biomass burner, it often encounters the phenomenon of coking and ash accumulation in the nozzle and the furnace, which not only affects the uneven heat exchange of the heating surface of the burner and aggravates the wear of the heating surface, but also causes the normal production to fail due to the inability to raise the temperature. What causes the biomass burner to coke and accumulate dust? How to solve it? Measure 1: Biomass pellet fuel selection requirements: First: When choosing bio-particle fuel, it is best to choose a single pure wood pellet. Generally, normal pure wood pellets are not easy to coke and accumulate dust. The best on the market are miscellaneous woods, such as elephant wood, pine wood, and mahogany. If acceptable, mahogany can be used. The pellets made of pure mahogany have higher calorific value than other pellets and ensure no coking; Second: the raw materials are not clean. , Or the raw material is oily, there will be dust or grease in the burned particles, and coking will also occur; third: the raw materials of biomass pellet fuel must be dry; fourth: use pulverized materials as little as possible, some particles It is pressed with wood powder, and the resulting particles are very hard, resulting in insufficient combustion and coking; Fifth: The most suitable pellet fuel length for the biomass burner is 6 millimetres and 8 millimetres. The pellets are too short or too long. It is prone to coking and tempering. Measures 2. Requirements for the use of biomass burners: 1. The built-in parameters of the biomass burner must be changed at will. Changing the equipment parameters at will may easily cause abnormalities in the burner. If the equipment parameters need to be changed, please operate under the guidance of professionals; 　2 , During the working process of the biomass burner, the operator needs to pass through the fire observation port from time to time to observe the combustion of the particulate fuel in the furnace; 3. The coking method of the biomass burner: remove the equipment used by the burner and use it from the burner Lightly tap the coke block with a wooden or iron rod to separate it from the gasification chamber; 4. Under the condition of ensuring that there is no smoke, reduce the air intake to reduce carbon formation; 5. In addition to the above reasons, biomass The air distribution of the burner, furnace design, feeding speed, etc. will also cause coking. The new type of burner produced by Shenghuo can automatically discharge slag and easily solve the problem of burning and coking.
