Description

An environmentally friendly chimney

Technical Field

The utility model relates to the technical field of chimneys, in particular to an environmentally friendly chimney.

Background Art

Energy conservation and environmental protection is a topic that people are most concerned about at present. The main function of the chimney is to remove fire and smoke, exhaust smoke, and improve combustion conditions. The boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, and can also be converted into mechanical energy through a steam power device, or mechanical energy can be converted into electrical energy through a generator. During the use of the boiler, the generated flue gas needs to be discharged with the help of a chimney.

During outdoor activities, some portable boilers are usually used to cook food. However, some boilers will produce smoke during use, and the chimney that comes with the boiler only has the effect of guiding the smoke. It cannot ensure that the smoke generated by the boiler can be safely discharged into the atmosphere, and it cannot effectively recover the heat in the smoke. The heat will be absorbed by the outer wall of the chimney during the discharge process, causing the temperature of the outer wall of the chimney to rise, which is easy to burn surrounding people during use, thereby wasting heat energy and increasing the danger of using the chimney. To this end, we propose an environmentally friendly chimney.
