[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 and Figure 4, which is a structural schematic diagram of a steam generator 200 provided in an embodiment of the present invention. The steam generator, for example, includes: a steam generating component 210 and a heating cylinder 260. The heating tube 260 is sleeved on the outside of the steam generating assembly 210, and forms an exhaust gas combustion heating area 230 between the heating tube and the steam generating assembly 210. The exhaust gas combustion heating area 230 is provided with a combustion catalyst for catalyzing the exhaust gas reaction. The exhaust gas reacts with the combustion catalyst in the exhaust gas combustion heating area 230 to burn and release heat to heat the steam material in the steam generating assembly 210 to generate steam. The steam material can be, for example, a mixed liquid of methanol and water. The heating tube 260 is provided with an exhaust gas inlet 221 connected to the exhaust gas combustion heating area 230. The exhaust gas conveying pipe (not shown in the figure) is connected to the exhaust gas inlet 221 to convey the exhaust gas to the exhaust gas combustion heating area 230. The exhaust gas reacts with the combustion catalyst in the exhaust gas combustion heating area 230 to burn and release heat. The temperature gradually rises to the gasification temperature to heat the steam material to generate steam. The exhaust gas after combustion becomes exhaust gas and flows out from the exhaust gas outlet 223 and is output from the exhaust gas output pipe 280. The harmful exhaust gas can be conveyed to the exhaust gas processor for treatment, and the harmless exhaust gas can be conveyed to the atmosphere for discharge. The tail gas reacts with the combustion catalyst to burn and heat the steam material to generate steam, thereby realizing the secondary utilization of the tail gas energy, reducing the direct emission of the tail gas, and being able to fully and evenly heat the steam material, improving the heating efficiency, and increasing the steam generation efficiency.

[0039] Combination Figure 3 The steam generator 200 includes a liquid inlet manifold 100, which includes: a first flange 101 and a second flange 102.

The middle part of the first flange 101 and / or the second flange 102 is recessed to form a concave cavity, and the concave cavity constitutes the liquid inlet manifold 100; the liquid inlet manifold 100 is a cavity with a liquid storage capacity of less than 30L, which realizes a liquid storage capacity less than the national standard liquid storage cavity, and does not need to be reported, which is convenient for storing the steam materials required to generate steam. By providing a recessed cavity between the first flange 101 and / or the second flange 102, a liquid storage cavity can be formed in the entire device without adding a new structure, which saves costs on the one hand; on the other hand, the cavity formed by the recessed flange is relatively small in volume, so that the solution can be directly circulated and heated after entering the cavity, thereby further reducing the volume of the entire device and not constituting a pressure vessel, thereby reducing the number of inspections, etc.

[0040] For details, see Figure 2 and Figure 4, a first electric heater 240 is provided in the liquid inlet manifold 100 and the liquid inlet manifold 100 is provided with at least one first opening (not shown in the figure) connected to the steam generating assembly 210, and the steam generating assembly 210 includes: a steam section 211 and at least one steam transmission pipe 214.

By adopting the cooperation of the heat storage ball and the fins 215, the heat storage efficiency and heat exchange efficiency can be further improved.
