Abstract

The invention relates to a multi-working-medium direct mixing combustion device and a control system and method thereof. The technical problem that an existing water vapor generator control system is not suitable for a multi-working-medium direct mixing combustion device is solved. The system comprises a main controller module, a multi-working medium transfer injection control module, a softened water treatment control module, a sensor redundancy test module, an electromagnetic valve energy-saving protection module and a liquid level test module. The method comprises the following steps of: 1, in a starting mode, supplying power to each electromagnetic valve by adopting timing control and a direct current (DC) 24V power supply; 2, judging whether ignition succeeds or not, and if yes, switching to a working mode; if not, returning to the step 1; 3, in the working mode, logic control and a DC10V power supply are adopted to supply power to each electromagnetic valve; 4, judging whether a power-off mode is started or not, and if yes, switching to the power-off mode; if not, returning to the step 3; and 5, in a shutdown mode, timing control and a DC24V power supply are adopted to supply power to each electromagnetic valve until shutdown is finished.

Description

technical field [0001] The invention relates to a steam generating device, in particular to a multi-working substance direct mixing combustion device and its control system and control method. Background technique [0002] In recent years, the rapid steam generation technology based on the principle of rocket engines has been applied in the field of rocket engine tests, mainly to meet the needs of high-temperature steam for jet pump vacuuming in the field of high-altitude simulation tests of rocket engines. It has the characteristics of fast steam generation, high temperature High pressure, energy saving and environmental protection, small footprint, low cost and other significant advantages have become the focus of many industries. Common steam generators in the field of rocket engine testing mostly use liquid oxygen, gas oxygen, alcohol, demineralized water and other working fluids to mix and burn to generate water vapor. Limited, poor reliability of multiple ignition sta...
