[42] The low-emission environmentally-friendly atmospheric high-temperature steam generator of the present invention is used as follows:

[43] First, the flame and flue gas generated by the combustion of the burner enters the combustion inlet chamber 240, then moves upward, enters the square groove 300, and is absorbed by the flame arresting member 212 in the square groove 300. The water in the hollow casing 20 is heated, and the heated water starts from the second cavity 230, passes through the communication pipe 280 and enters the first cavity 220. Then passes through the communication pipe in the upper portion of the first cavity 220. The 280 enters the other second cavity 230, and thus continues to circulate until the first cavity 220 up to the top of the hollow casing 200 is discharged through the air outlet pipe 203. The flow direction is shown by the arrow on the arrow in Fig. 11.

[44] In the use of 吋, the water of the upper second cavity 230 is transported through the first water pipe 215 to the bottom of the hollow casing 200, and the second cavity 230 is mixed with the water at the bottom, because the temperature difference between the two waters is large. Therefore, the steam will expand and then expand a plurality of times, and the number of expansions will be more than 10 times, thereby causing an increase in the rate of occurrence. On the one hand, the water inlet controller disposed on the top of the hollow casing 200 can fully absorb the energy of the exhaust gas, raise the temperature of the tap water at normal temperature, and then flow into the first inlet pipe 201 through the introduction pipe 405, and then enter through the hole 100 0 and the hole 2000.

The low-emission environmentally-friendly atmospheric high-temperature steam generator works to generate steam enthalpy. When the steam pressure is too large, it is discharged from the hole 2000 or the hole 1000 of the first inlet pipe 201 to reduce the pressure and ensure the safety of use. In addition, you can also choose to add one to the top of Figure 10 and Figure 11. The control door 1000 and the hole 2000 open and close the control door, and the control door opens and releases the pressure when the pressure reaches a certain level.
