Electric-heating superheated steam boiler

Abstract

The invention discloses an electric-heating superheated steam boiler. The electric-heating superheated steam boiler comprises a lower header, a saturated steam electric heater header, an upper header, a separation header and a superheated steam electric heater header. The upper header and the lower header are connected through a communication pipe I and a communication pipe II, to form an integrated structure. The saturated steam electric heater header is arranged between the upper header and the lower header. The separation header is connected with the upper header. The superheated steam electric heater header is arranged above the upper header and connected with the separation header through an elbow pipe. Saturated steam electric heaters of various specifications are arranged in the saturated steam electric heater header. A superheated steam electric heater is arranged in the superheated steam electric heater header. According to the electric-heating superheated steam boiler, the amount of generated saturated steam is stable, the temperature of superheated steam is stable, the investment cost is low, pollution is small, and the noise is low.

Description

technical field [0001] The invention relates to an electric heating superheated steam boiler, which belongs to the technical field of heating equipment. Background technique [0002] The electric heating superheated steam boiler uses electricity as the energy source, converts the electric energy into heat energy, heats the softened water in the pot, and vaporizes it to generate saturated steam. The superheater section uses electric energy to continue heating the saturated steam to make it superheated. Thermal energy conversion equipment . In the past, superheated steam boilers often adopted a double-drum vertical structure. This design is a coal-fired superheated steam boiler structure. The structure is shown in figure 1 , mainly consists of upper drum (10), lower drum (20), upper left and right headers (30), upper front header (40), upper water wall tube (50), combustion chamber (60), first The return convection pipe (70), the second return convection pipe (80), and the s...

AI Technical Summary

Problems solved by technology

[0003] 1. The amount of steam is relatively large, and there are generally no products below 10t / h

[0004] 2. High investment cost, large land occupation, long construction and installation period

[0005] 3. Heavy pollution and high noise, which do not conform to the national strategic layout of energy conservation and emission reduction

[0006] 4. The superheated steam temperature control system is complicated, and the superheated steam temperature is difficult to stabilize
