The principle of heating water takes the HJ submerged steam-water mixer as an example: the HJ submerged steam-water mixer is made of all stainless steel, and the nozzle inside the submerged steam-water mixer is a small inclined hole. Steam is sprayed into the shell at high speed from the nozzle of the submerged steam-water mixer, which has a strong spraying effect on the surrounding cold water. Cold water enters the submerged alkali mixer through inclined holes on the outer wall of the submerged alkali mixer to exchange heat with high-speed steam, and the high-speed steam spirals up in the shell. The formed rotating steam can absorb steam and eliminate noise. At the same time, the heated water is continuously led out from the upper surface of the shell, which drives the water around the submerged soda mixer to flow, thus heating the water in the whole water tank.
The principle of heating air takes ZGL finned tube radiator as an example: when steam flows through the finned tube base tube, it transfers heat to the inner wall of the base tube through convection, the inner wall transfers heat to the outer wall and fins through heat conduction, and the outer wall and fins finally heat the surrounding air through forced convection and radiation.
