Description

Technical Field

[0001] The utility model relates to the technical field of expanded perlite combustion devices, in particular to an expanded perlite gas combustion energy-saving device. Background Art

[0002] Expanded perlite is a material with light apparent density, low thermal conductivity, good chemical stability, wide operating temperature range, low moisture absorption capacity, and is non-toxic, odorless, fire-resistant, and sound-absorbing. It is widely used in various industrial sectors.

[0003] The high-temperature roasting perlite expansion furnace is a production equipment for expanded perlite. Natural gas is used as fuel to provide a high-temperature heat source for the perlite expansion process. The high-temperature perlite expansion furnace feeds perlite through a feeding pipe, and the perlite is burned by flames. The traditional high-temperature perlite expansion furnace has a small number of feeding ports. The perlite is discharged more concentratedly in some parts of the combustion furnace, which will lead to uneven combustion. The perlite accumulation in the concentrated feeding area is thicker, and the perlite particles inside may not be able to fully contact the high-temperature gas, resulting in insufficient heating and poor expansion effect. Concentrated feeding will also affect heat transfer, thereby reducing the overall combustion efficiency of the combustion furnace. In order to solve the above problems, we proposed this expanded perlite gas combustion energy-saving device. Utility Model Content
