How to store energy in firewood stoves

By burning wood to store heat energy, using the heat capacity of stove materials, using heat storage materials, etc.

1. Burning wood to store heat energy: Wood stoves can generate heat energy by burning wood and store it in the furnace body. When wood burns, the heat released will be absorbed by the furnace body and stored. The furnace body is made of high temperature resistant material, which has large heat capacity and can effectively absorb and store heat energy. The flue gas generated in the combustion process can also be circulated through the flue system of the furnace body, further improving the storage efficiency of heat energy.

2. Using the heat capacity characteristics of furnace materials: The heat capacity characteristics of furnace materials are the key to the energy storage of wood stoves. The heat capacity of furnace material refers to the heat absorbed or released by the material with unit mass or unit volume when the temperature changes. Selecting materials with large heat capacity, such as refractory bricks and ceramics, can increase the thermal energy storage capacity of the furnace body. In this way, in the combustion process, the furnace body can absorb more heat, and the stored heat energy is slowly released after combustion, thus prolonging the service time of heat energy.

3. Use heat storage materials: In addition to the heat capacity of the furnace material itself, special heat storage materials can be used to increase the energy storage capacity of the wood stove. Thermal storage materials are substances with large heat capacity, such as graphite, thermal storage bricks and thermal storage water tanks. These materials can absorb a lot of heat energy when burning, and slowly release the stored heat energy after burning to realize long-term storage and utilization of heat energy.
