Description

technical field

[0001] The invention relates to a conductive heating ceramic tube and a preparation method thereof. Background technique

[0002] Most of the traditional water heating methods provide low-temperature heat by burning coal and gas. Because the chemical energy in the fuel is not fully utilized, there is a huge waste, and a large amount of CO is emitted during combustion 2 , SO 2 Harmful substances such as dust and dust not only cause environmental pollution, but also lead to ecological damage, such as: greenhouse effect, acid rain, etc.

[0003] Electric heat source is a clean and direct energy source. With the development of nuclear energy and hydropower generation, extensive use of electric heating has great significance for saving coal and gas resources and protecting the environment.

[0004] The existing electric heating methods mainly include wire heating electric heaters, air conditioners, electric heating films, cable floors, etc. Electric heaters wi...
