Control method for steam production process and pipeline directly-heated type steam generator

Abstract

The invention belongs to the technical field of steam generators and provides a control method for a steam production process. The steam production process is controlled by controlling the water inflow quantity. Meanwhile a steam generator applying the control method is provided. The core of the steam generator is an evaporator. The evaporator is a section of pipeline. An electrode connected withan alternating current power supply is arranged in the pipeline. Water is supplied to the evaporator, electric currents are generated, and steam is generated. The water supply is increased, electric currents are increased, and more steam is generated. The water supply is reduced, electric currents are reduced, and less steam is generated. The water supply is stopped, electric currents return to zero, and no steam is generated. Through the steam generator, water inflow can be controlled automatically according to the needs for steam, constant current output or constant pressure output of steamis achieved, and thus the needs of different users for steam can be met. The steam generator can be fast started and stopped in seconds, is started if used, and is stopped if not used. The steam generator is far smaller than a traditional electric boiler, does not belong to pressure vessels, but can provide high pressure steam. The steam generator is not a boiler but can replace a boiler.

Description

technical field [0001] The invention belongs to the technical field of steam generators, and more specifically relates to a method for controlling a steam production process and a pipeline-type direct-heating steam generator. Background technique [0002] Steam is widely used in heating, cooking, disinfection, sterilization, ironing, distillation and maintenance of cement products and other fields. Steam production mainly relies on boilers. [0003] Traditional boilers, whether they are coal-fired boilers, oil-fired boilers, gas-fired boilers, or electric boilers, heat water through heat conduction to generate steam. The heat transfer area is a necessary condition for heat conduction. In order to obtain a sufficient heat transfer area, enough water must be stored. [0004] Due to the constraints of heat transfer area and water storage capacity, traditional boilers cannot start and stop quickly. [0005] Due to the constraints of heat transfer area and water storage capaci...

AI Technical Summary

Problems solved by technology

Although heat is no longer transmitted through insulating materials, electromagnetic induction cannot convert all electrical energy into heat energy, and there are efficiency and cost issues

Moreover, it is still limited by the heat transfer area and water storage capacity.

[0012] Coal-fired boilers, oil-fired boilers, etc., are also restricted by the heat transfer area and water storage capacity, and there are also environmental pollution problems
