[0002] Boilers, as an indispensable equipment in modern industry and life, have the core function of energy conversion and transmission. In short, a boiler is an energy converter that can receive energy from different sources, such as chemical energy and electrical energy in fuel, and then, after internal processing and conversion, finally output steam, high-temperature water or organic heat carrier with significant thermal energy.
[0003] Boilers have a wide range of applications. They not only provide necessary thermal energy support for industrial production, but also penetrate into all aspects of people's lives. In industrial production, the hot water or steam generated by the boiler can be directly used for heating, drying, distillation and other processes, greatly improving production efficiency. In daily life, boilers also play an indispensable role. They provide us with daily necessities such as hot water and heating, making our lives more comfortable and convenient.
[0004] What is more worth mentioning is that boilers have demonstrated extremely high efficiency and flexibility in energy conversion and utilization. The thermal energy output by the boiler can not only be used directly, but also be further converted into mechanical energy through a steam power device, and then the mechanical energy is converted into electrical energy through a generator, realizing multi-level utilization and efficient conversion of energy. This energy conversion and utilization method not only improves the efficiency of energy utilization, but also helps to achieve sustainable development of energy. As an energy conversion device, the boiler plays a vital role in modern industry and life. It not only provides us with the necessary thermal energy support, but also promotes the development and progress of social economy through its efficient energy conversion and utilization method.

[0026] The heating mechanism also includes a fan 7 and a guide tube 8. The fan 7 is fixed on the top of the furnace body shell 1. The input end of the fan 7 passes through the top of the furnace body shell 1 and is fixed with a guide tube 8. The bottom of the guide tube 8 is fixed to the top of the ash cleaning port 9. Through the arrangement of the fan 7 and the guide tube 8, heat can be passed through the heating tube 10 to heat and heat the water, so that the flame burns in a downward direction, the fuel burns more fully, wasteful combustion is reduced, energy saving is achieved, and the safety is higher.

[0027] An auxiliary water inlet tank 6 is fixed between the furnace body shell 1 and the combustion chamber 2. The auxiliary water inlet tank 6 is connected to the boiler inner cavity 3. A float 14 is arranged on the inner side of the auxiliary water inlet tank 6. A water inlet 11 is opened at one end of the auxiliary water inlet tank 6. The setting of the float 14 facilitates automatic water replenishment in case of water shortage.
[0028] Example 2
[0029] Embodiment 1 is further optimized, specifically, as Figure 4 As shown, a steam discharge port is provided on the top of the furnace body shell 1, and a first steam-water separation baffle 12 and a second steam-water separation baffle 13 are fixed to the top of the inner side of the boiler cavity 3. The first steam-water separation baffle 12 and the second steam-water separation baffle 13 are both arranged to be tilted downward. Through the arrangement of the first steam-water separation baffle 12 and the second steam-water separation baffle 13, downward reverse gas outlet is achieved to make the water naturally drop, and the dry steam rises. After the steam water is separated, it naturally drops and drips into the boiler for secondary heating, thereby achieving the goal of not wasting hot water.
[0030] From the above, we can know that:
[0031] The utility model aims at the technical problem that the existing boilers on the market are not very perfect in steam drying, and the steam humidity is high.
