Embodiment Construction
[0031] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
[0032] like Figure 1-Figure 3 As shown in the figure, a heat storage type direct current steam generation system of the present invention uses an electric heat accumulator, including a high temperature accumulator 1, the energy storage temperature is 280°C to 580°C, and the hot air flow after the heat exchange of the high temperature accumulator The hot gas channel 103 in the passing direction includes a high temperature accumulator and a steam generator tube. The high temperature accumulator includes an energy storage body, a low temperature gas inlet channel and a hot gas channel. The low temperature gas enters the energy storage body from the low temperature gas inlet channel 102 for heat exchange. High temperature gas is generated, the high temperature gas is passed into the hot gas channel 103, the steam generator tube 12 extends into t...

According to the heat storage type straight-flow steam generation system and the control method thereof, the heat storage type straight-flow steam generation system comprises a high-temperature energy storage device and a steam generator pipe, the high-temperature energy storage device comprises an energy storage body, a low-temperature gas inlet channel and a hot gas channel, and low-temperature gas enters the energy storage body from the low-temperature gas inlet channel to exchange heat to generate high-temperature gas; high-temperature gas is introduced into the hot gas channel, the steam generator pipe extends into the hot gas channel to continuously heat to generate steam, and water flows through the steam generator pipe to be heated to generate steam and is discharged through an outlet of the steam generator pipe. A temperature sensor and a pressure sensor are arranged at an outlet of the steam generator pipe, the circulation speed of high-temperature gas is controlled through PID negative feedback, and constant temperature or constant pressure of steam at the outlet is kept. According to the heat storage type straight-flow steam generation system and the control method thereof, the pressure of generated steam is stable, the heat energy loss is small, and steam production is safe.
Description
technical field [0001] The invention relates to the technical field of steam generation, in particular to a heat storage type once-through steam generation system and a control method thereof. Background technique [0002] A steam generator is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. As a thermal energy equipment, the steam generator can be divided into many kinds of incineration media. The steam generator is classified by the incineration medium. The biggest disadvantage of coal-fired boilers is that they are not environmentally friendly and contain a large amount of sulfur. The emissions after incineration will cause severe air pollution and are facing the situation of being phased out. Biomass steam generators have higher initial investment costs. Biomass steam generator boiler systems are generally much larger than oil or natural gas fueled boilers, and the fuel requires a separate storage a...
