A kind of internal combustion type kettle

Abstract

The invention discloses an internal combustion type kettle. It includes an annular water cavity surrounded by the outer wall and an internal combustion chamber surrounded by the inner wall, as well as curved walls, fins, water injection ports, exhaust ports, etc.; in the structural design, the knowledge of heat transfer and fluid mechanics is used. Reasonably optimize the heat transfer process, significantly increase the contact area between the flame and the wall of the kettle, reduce heat transfer resistance, and reduce heat energy loss. The flat conical internal combustion chamber used not only blocks the direct contact between the flame and the air, but also increases the residence time of the high-temperature flue gas; the curved wall and fins significantly increase the heat transfer area and enhance the The convective heat transfer intensity on the gas side. It not only improves the thermal efficiency, but also achieves the effect of energy saving and environmental protection.

Description

technical field [0001] The invention relates to a household energy-saving gas water kettle, in particular to an internal combustion water kettle with an internal combustion chamber. Background technique [0002] As we all know, the combustion and heating methods of ordinary kettles on the market are mostly open, and the burning flame is located at the bottom of the kettle body. However, part of the flame is directly discharged into the surrounding air without fully contacting the wall of the kettle. Cause 30%-40% heat energy to be dissipated in vain through the surrounding air; in addition, in the open combustion heating method, the contact surface between the flame and the entire kettle is limited to the circular plane at the bottom of the kettle, and the heat transfer area is relatively small. Small, not conducive to the exchange of heat energy, not conducive to energy saving. [0003] Chinese patent CN 201468988 U discloses an internal combustion type kettle. The main s...

AI Technical Summary

Problems solved by technology

The internal-combustion kettle aims at the disadvantages of low thermal efficiency and poor performance of the existing technology; the knowledge of heat transfer theory and fluid mechanics is used in the structural design, and the heat transfer process is reasonably optimized to increase the flame and the temperature of the kettle. The contact area of ​​the wall reduces the heat transfer resistance and heat energy loss, which not only improves the thermal efficiency, but also achieves the effect of energy saving and environmental protection
