Electric thermal storage preheating steam generator

Abstract

The invention discloses an electric thermal storage preheating steam generator. The electric thermal storage preheating steam generator comprises a thermal storage open type water tank. A water outletof the thermal storage open type water tank is connected with a suction inlet of a pressure pump. An outlet of the pressure pump is connected with a water inlet of a heating pressure-bearing water pot. A heating device and a second temperature sensor are arranged inside the thermal storage open type water tank. A first electric heater, a liquid level sensor, a pressure sensor and a first temperature sensor are arranged inside the heating pressure-bearing water pot. A safety valve and a steam outlet are arranged on the top of the heating pressure-bearing water pot. The electric thermal storagepreheating steam generator can preheat water with low-price electricity at the periods of valley electricity at night and common-price electricity during daytime, steam is generated through preheatedhot water when steam is needed for use, the electrical load during steam generation is decreased, the operating cost of a system is reduced then, and the electrical load of the system is decreased aswell.

Description

technical field [0001] The invention relates to the technical field of steam supply, in particular to a steam generator. Background technique [0002] There are many fields that need to use steam in daily production and life, such as hotels, schools, laboratories, food processing, industrial manufacturing and other fields. [0003] Usually, the sources of steam include municipal centralized steam supply system, regional steam supply system, and distributed steam supply system. [0004] Production steam heating heat sources include power plant extraction to supply steam, coal-fired boilers to produce steam, gas-fired boilers to produce steam, oil-fired boilers to produce steam, electric boilers to produce steam, etc. [0005] Different steam users have different steam usage characteristics. Industrial users usually use relatively small changes in steam consumption, relatively stable steam consumption, low heat loss, and high efficiency of pipes and boilers; while buildings u...

AI Technical Summary

Problems solved by technology

However, these electric steam generators use electricity as a heating source, and the steam usage peak of steam users often occurs during the peak electricity and peak time periods when the electricity price is higher during the day, resulting in higher operating costs of the system, and during the peak steam usage period The electricity load is concentrated, and the impact of the electricity load is large

[0007] The aforementioned centralized steam system and distributed electric steam generator system have the disadvantages of high energy consumption, high operating costs, and large impact of electricity load
