Electric boiler--- Liquid regenerative electric boiler

Operating principle:

Regenerative electric boiler takes the electric boiler as the heat source, takes advantage of cheap electricity at night, uses water as the heat storage medium for heating, and stores it in the heat storage tank. The electric boiler is shut down during peak hours of the power grid, and the hot water stored in the water storage tank is used for heating. The water outlet temperature can be arbitrarily set between 35℃ and 90℃.

 

Characteristics of liquid regenerative electric boiler:

1.Electric boiler has no combustion, no discharge of harmful gases, no pollution, no noise, which is the pure green environmental protection product with least pollution among all kinds of heating boilers.
2.High degree of automation, safe and stable operation, multiple automatic protections such as over temperature,over voltage, over current, short circuit, water-break and default phase, realize mechanical and electrical integration.
3.The electric boiler is small in size, the building structure is simple and compact, and it does not need chimney and fuel stacking area.
4.High thermal efficiency, up to 98% and above.
5.Outlet water temperature and heating time can be adjusted arbitrarily.
6.Make full use of off-peak electricity price, low operating cost.

Advantages of liquid regenerative electric boiler

1.It is green energy, which has the advantages of no noise, no pollution, easy installation and use, etc. It can use the off-peak power to work, realize energy storage, and achieve the most economical operation mode, especially suitable for the areas with higher requirements on environmental protection and safety.
2.Mechanical & electrical integration, compact in size, take less area, easy to install and transport.
3.Reasonable arrangement of electric heating pipes and distribution system realize mechanical & electrical integration to facilitate replacement and maintenance.
4.Intelligent control system, using computer setting program to realize automatic unattended unit, can work automatically within the set time and at the set temperature, save energy, reduce heat loss, and reduce costs.
5.The electric heating tube starts and stops at different stages to reduce the impact on the power grid and ensure the safe operation of the electric boiler. It has safety protection measures such as overtemperature, overload, short circuit, leakage of electricity and water shortage.
6.The perfect combination of water level induction system and intelligent water inlet device can achieve continuous heating, automatic water replenishment and water condensation, greatly reducing the discharge of air pollutants, and effectively protecting the environment.

Operating principle:

In the preset off-peak period of power grid or abandoned wind power, the automatic control system switches on the high-voltage switch, and the high-voltage grid supplies power to the high-voltage heating element, and the high-voltage heating element converts electric energy into heat energy and is continuously absorbed by the high-temperature heat storage element. When the temperature of the high-temperature heat storage element reaches the set upper limit or the power grid reaches the end of the off-peak period, the automatic control system will turn off the high-voltage switch, the power supply of the high-voltage grid will stop, and the high-voltage heat storage element will stop working. There is a heat output controller between the high temperature heat storage element and the high temperature heat exchanger, which converts the high temperature heat stored in the high temperature heat storage element into hot water or steam to output.
