XCW-500 Energy Storage Electric Boiler

XCW-500 Energy Storage Electric Boiler

The XCW-500 Energy Storage Electric Boiler is an off-peak electricity heat storage heating equipment tailor-made by Jingyu Thermal Energy for the severe cold regions of Northeast China. With a heat storage power of 500kW and a heat release power of 200kW, it utilizes 8 hours of nighttime off-peak electricity for heat storage to meet 24-hour all-weather heating needs. It is particularly suitable for industrial and commercial heating projects in regions with peak-valley electricity pricing such as Heilongjiang, Jilin, and Liaoning.

Technical Principle

The equipment adopts a two-stage energy storage technology combining "solid magnesium oxide + phase change heat storage." The first-stage energy storage uses magnesium oxide heat storage bricks, which feature high density, large specific heat capacity, and temperature resistance of up to 1000°C; the second-stage peak shaving employs molten salt phase change materials, which release latent heat when the temperature of the heat storage bricks drops, maintaining stable heat supply.

During heat release, a variable-frequency fan delivers air into the heat storage body for heating, and then transfers the heat to the heating circulating water through a high-efficiency air-water heat exchanger. The system enables off-peak heat storage and stable daytime heat release, reducing operational pressure during peak electricity pricing periods.

Economic Benefit Analysis

Comparison Scheme	Daily Power Consumption	Daily Electricity Cost	Heating Season Electricity Cost
Standard Electric Boiler (Peak Electricity Operation)	Approx. 2400kWh	Approx. RMB 2400	Approx. RMB 432,000
XCW-500 Energy Storage Solution	Approx. 2640kWh	Approx. RMB 792	Approx. RMB 143,000

Based on Harbin's peak-valley electricity pricing scenario, the energy storage solution can significantly reduce peak-hour electricity costs, with equipment investment payback period typically around 2-3 years. The equipment occupies approximately 5㎡ and does not require the construction of a traditional dedicated boiler room.

Application Scenarios in Northeast China

Logistics Parks and Warehouse Heating: Suitable for large-area, all-weather low-temperature anti-freezing scenarios, capable of using off-peak electricity to handle basic heat loads.

Industrial Plant Heating: Can be operated in conjunction with electromagnetic boilers. The energy storage boiler handles the base load while the electromagnetic boiler is used for peak shaving, improving overall economic efficiency.
