Preferably, a wind shield 44 is arranged between the flue gas input port 46 and the heat exchanger 5, so that a path of flue gas entering the box 41 from the burner 3 is limited, the flue gas passes through the heat exchanger 5 as much as possible instead of directly passing through a gap between the heat exchanger 5 and the inner wall of the box 41 and is discharged from the smoke outlet 43, and the heat exchange effect of the heat exchanger 5 is indirectly improved.

Raw material water after the double preheating of heat recovery structure 10 and waste heat recovery device 4 inputs combustor 3 internal heating under the effect of circulating pump 81, because raw material water after the double preheating has higher temperature, consequently combustor 3 can produce high-temperature water fast, compares with other steam generator, and required fuel is still less under same play water speed, therefore tail gas emission is still less, and carbon dioxide emission is far less than current steam generator. High-temperature water enters the steam-water separator 60, is quickly vaporized in the steam-water separator 60 to generate steam, meanwhile, the temperature of the rest part of water is reduced and is continuously output from the water outlet 63, hot water is continuously input from the water inlet 61, and the water in the barrel body 6 is always at a high temperature and a reasonable water level under the detection of the water level switch 74, so that the barrel body 6 can keep the steam to be quickly generated.

The controller can integrate devices such as a display, an alarm and the like, a wind pressure detector can be arranged on the fan, and a water flow switch can be arranged on an inner pipeline of the steam generator. The control flow of the controller to the steam generator is as follows: 1. and when the starting button is pressed down, the controller, the circulating pump and the fan are electrified. 2. The controller controls the circulating water pump and the fan to work, then the controller detects whether a water flow and air pressure signal exists in the water flow switch and the air pressure detector, if the water flow and air pressure signal is detected, the controller starts to ignite, a gas valve group in the combustor is opened, and whether ignition is successful is detected through a flame sensor in the combustor after 4 seconds of delay; if the ignition is unsuccessful, the ignition will be tried again, and if the ignition is unsuccessful for three times, an alarm is given. 3. If the ignition is successful, the controller starts to detect various signals, such as a steam pressure signal, a flame signal, a water flow signal, a wind pressure signal and a water level signal, and if any one of the signals is abnormal, the controller closes a gas electromagnetic valve of the combustor; in order to avoid signal false alarm, when the controller detects that the signal is abnormal and causes flameout, the controller can ignite again, and if the ignition is unsuccessful for three times, the alarm is used for alarming. 4. When the steam pressure reaches the upper pressure limit set by the electric contact pressure gauge in normal operation, the controller can automatically extinguish the fire, and when the steam pressure reaches the lower pressure limit, the controller re-ignites, so that the steam pressure is always in the set range. 5. When the shutdown button is pressed, the controller detects a shutdown signal, the controller controls the flameout, and the circulating water pump is turned off after two minutes. To prevent the burner temperature from being too high.
