When using the gas burner, the phenomenon of coking and ash deposition in the nozzle and furnace is often encountered, which not only affects the uneven heat exchange of the heating surface and aggravates the wear of the heating surface, but also fails to raise the temperature, resulting in the failure of normal production. Then, what causes the coking and ash deposition of gas burner? How to solve it? Let's take a look!

   When selecting fuel for gas burner, single pure wood particles shall be selected. Generally, normal pure wood particles are not easy to coke and accumulate ash. At present, miscellaneous wood is better in the market, such as wood, pine and mahogany. If acceptable, mahogany can be selected. The particle calorific value made of pure mahogany is higher than that of other particles, and no coking can be ensured. The gas burner uses the appropriate particle fuel with the length of 6 mm and 8 mm. If the particle is too short or too long, coking and tempering are easy to occur.

   The raw materials of the gas burner are not clean in dust removal, or the raw materials are oily, and the burning particles also contain dust or grease, so coking will also occur. Try to minimize the particles made of crushed materials. Some particles are pressed with wood powder. As a result, the particles are very hard, resulting in insufficient combustion and coking. The raw materials of fuel must be dry. The built-in parameters of the gas burner must be changed at will. Changing the equipment parameters at will is easy to cause abnormalities of the gas burner. If it is necessary to change the equipment parameters, please operate under the guidance of professionals.
