Because the hot fluid is heated in a flowing manner, heat still flows away if the heat is not exchanged in time (traditional electric heating and fuel oil heating are that a heat source is always maintained in a water storage rod tank (namely static heating), heat exchange efficiency is high and low, the heat is finally released into water, the heat exchange efficiency is affected only by a long heating time end and cannot cause excessive increase of heat loss), the heat flowing away along with the hot fluid is equivalent to heat loss, and the existing steam generator is heated in a static state, so that water is kept still in the heating process (because the static heating does not need water to move), and the heat exchange speed between the heat exchanger and the water is slow; the position of the heat exchanger is fixed, when the water levels are different, the difference of the utilization rate of heat is large, especially when the distance between the heat exchanger and the liquid level is large, the ratio of the heat dissipated along the direction far away from the liquid level by the heat transferred by the heat exchanger to the heat transferred by the heat exchanger towards the liquid level direction and evaporated by initial water is large, the larger the ratio is, the lower the heat utilization rate is, the installation of all the heat exchangers is suitable for being closer to the liquid level and farther from the bottom of the container, but the installation mode can lead the exchange water to be evaporated to the liquid level quickly and descend to expose the heat exchanger (namely, the evaporation time is short), therefore, the existing heat exchanger is installed at the bottom of the container to sacrifice the heat utilization rate and achieve the effect of delaying the evaporation time.
