Embodiment 1

[0025] Embodiment 1: structure such as figure 1 with figure 2 As shown, among them, figure 1 It shows that the evaporation capacity is 1T / H, and the working pressure is 8Kgf / cm 2 , a schematic diagram of an electric heating superheated steam boiler with a superheated steam temperature of 450 ° C, vertical layout. The boiler is divided into two parts, including the boiler body 1 that generates saturated steam and the superheater 10 that generates superheated steam. The electric heating tubes 2 and 8 in the boiler body 1 and the superheater 10 are all single-ended single-outlet electric heating tubes, which adopt Y-shaped connection , the shell of the electric heating tube 20 and the shell of the boiler body 1 and the superheater 10 serve as neutral points and are reliably grounded. Boiler body 1 has a cylinder diameter of 900 mm and a wall thickness of 10 mm; its two ends are welded with elliptical heads. The boiler body 1 is arranged in a vertical structure, its lower par...

Embodiment 2

[0027] Embodiment 2: as image 3 with Figure 4 As shown, the boiler body and superheater are arranged horizontally. Wherein, both ends of the cylinder body of the boiler body 1 are welded with flat-shaped heads. The lower part of the boiler body 1 is a water space, and the upper part is a steam space. 90 single-ended single-outlet electric heating tubes 2 with a thermal power of 8.5KW are connected to the flat head at one end of the body 1 through threads, and the electric heating tubes are arranged horizontally. The superheater 10 has a diameter of 700mm and a wall thickness of 8mm. One end of the superheater is welded with a flat head, and the other end is welded with a flange and is sealed by connecting the tube sheet with the flange. 96 single-end single-outlet electric heating tubes 8 with a diameter of 20mm, a length of 2000mm, and a thermal power of 3KW are inserted into the superheater 10 through the screw holes of the upper tube plate of the superheater and fixed ...

Abstract

The present invention provides an electroheating pipe superheated steam boiler, including boiler self-body for producing saturated steam and superheater for producing superheated steam, and the heating elements of boiler self-body and superheater are single-end single-outlet type electroheating pipes which are connected by adopting V-shaped mode, and the outer shell of the electroheating pipe and outet shell of boiler self-body are used as neutral point, and can be reliably grounded. Said invention overcomes the defect of traditional electrothermal boiler which can not produce superheated steam.

Description

technical field [0001] The invention relates to the technical field of electric heating boilers, in particular to a resistance electric heating tube superheated steam boiler. Background technique [0002] Electric boilers have a history of more than 50 years since their birth, and achieved great development in Europe and America in the late 1960s. The development and popularization and application of electric heating boilers in China have been done in the past five or six years. [0003] The electric heating boiler not only has a high utilization rate of electric energy, a high degree of automation, and is convenient to use and manage, but also has the advantages of small footprint, fast start-up, no solid fuel and slag treatment, and no pollution discharge. From an environmental point of view, electric heating boilers are the cleanest. If the electric heating boiler system is made into a heat storage system, it also has the effect of "shifting peaks and filling valleys" o...
