The chimney of the wall-mounted boiler is used to evacuate the high temperature fumes produced by combustion.
The boiler chimney is characterized in that the chimney is made by mixing, stirring and solidifying fibrous materials with acid-resistant clay prepared from boiler water. sodium or potassium soluble glass. The above-mentioned fibrous material is fiberglass cloth or short fiberglass; it can also be short fibers or fabric made from asbestos fiber or ceramic fiber. The above cement can be filled with aggregates of a certain particle size and proportion.
In order to meet the height and wind resistance requirements, a certain thickness of fiberglass can be added to the exterior surface of the chimney, or the chimney can be attached to a steel frame. Compared with existing technology, the present invention has the advantagescorrosion resistance, high temperature resistance, aging resistance, etc. Its service life is 3-5 times that of the existing iron plate fireplace, and the manufacturing cost is lower than that of the iron fireplace. plate fireplace.
Fume is a mixture of gas and smoke and is the main cause of air pollution in residential areas. The composition of combustion gases is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, hydrocarbons and nitrogen oxides. Smoke includes fuel ash, coal particles, oil droplets and high temperatures. cracked products. Environmental pollution caused by combustion gases is a composite pollution of multiple poisons.
