A gas-fired steam generator with variable air outlet diameter

Abstract

The invention provides a fuel gas steam generator with an air outlet diameter changing function. The fuel gas steam generator comprises a water tank and a burner; the burner comprises a burner seat; aplurality of air outlets for supplying combustion improvers to a burning head are formed in the burner seat; air supplying channels communicating with the air outlets are formed in the outer side ofthe burner seat; the multiple air outlets are formed from the lower portion to the upper portion; and from the lower portion to the upper portion, the diameters of the air outlets are gradually increased firstly, and then are gradually decreased in a certain position. The diameters of the multiple air outlets are changed from the lower portion to the upper portion, thus air is gradually mixed withfuel gas, and the full mixing effect is achieved.

Description

technical field [0001] The invention relates to an evaporator technology, in particular to a heat pipe evaporator with a new structure. Background technique [0002] Heat pipe technology is a heat transfer element called "heat pipe" invented by George Grover of Los Alamos National Laboratory in the United States in 1963. It makes full use of the principle of heat conduction and phase change medium. The rapid heat transfer properties of the heat pipe quickly transfer the heat of the heating object to the heat source, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe technology enables the radiator to ...

Problems solved by technology

The current evaporator is also widely used in the treatment of various diseases, especially in the treatment of chronic diseases caused by aging and old damage such as muscles and ligaments, such as the CN2167709Y patent, but in the current prior art, such as the CN2167709Y patent , because the steam generated directly by heating will cause the temperature of the generated steam to be too high, and it will cause too much moisture in the generated steam, and the drug may be deposited in the lower part because it is a particle, so the active ingredient in the ejected steam The content is too low, and the temperature is too high, and the degree of intelligence in the existing technology is not high, and effective intelligent operation cannot be carried out

[0005] In the prior art, there is uneven mixing of air and gas in the burner, resulting in insufficient combustion
