Background
At present, two groups of heating modes of a steam boiler are mainly provided, one is a fuel boiler, and the other is an electric boiler. If the water is simply heated to boiling at normal temperature and steam is continuously generated, the energy required for this is large because the specific heat capacity of water is large, regardless of whether the fuel boiler or the electric boiler. Moreover, most steam boilers consume a large amount of steam, so that in order to avoid dry burning and ensure enough steam quantity, the boilers need to continuously supplement new water in the heating process, and the steam quantity in the boilers is greatly reduced if the new water enters the boilers again at a lower temperature. And because of the addition of the new water, the energy required by the whole boiler for re-boiling is greatly increased, so that in order to reduce the energy required by the whole boiler, solar energy or air energy is generally adopted in the industry at present to preheat the new water added into the boiler so as to improve the temperature of the new water, reduce the energy consumption and simultaneously reduce the influence on the boiling water in the boiler caused by the over-low temperature of the new water.
Because the fuel boiler has small limitation and is generally not limited to the supply quantity of fuel, the application range is wider than that of an electric energy boiler. In the existing air energy boiler, in order to realize energy conservation, fresh water to be added into the boiler is generally preheated by air energy with small limitation, and the air energy utilizes the principle of reverse Carlo cycle mainly adopted by part of the air energy, so that the air energy heat pump capable of converting the air energy also needs external electric energy input in the process, and therefore the whole air energy boiler has certain limitation in some use occasions due to incomplete power supply facilities, lack of electric energy on site or incapability of ensuring normal operation of the whole air energy heat pump by proper voltage.
