Oven Heating Power

The calculation of Oven power usually needs to consider the following parameters:

1.baking product heating power: P1 = m1 * c * ΔT./t

• m is the mass of the article.

• c is the specific heat capacity of the article.

• ΔT is the temperature change of the article.

• t is the heating time.

2.Oven air heating power: P2=ρ*Q1*C*ΔT/t

• ρ is the density of air (at standard atmospheric pressure, room temperature air density is about 1.225kg/m3)

• V is the volume of air.

• C is the specific heat fusion of air.

• ΔT is the temperature change of the article.

• t is the heating time.

3.The Oven box heat absorption heating power: P3== m2 * c * ΔT / t

• m2 is the mass of heat-absorbing material of the box.

• c is the specific heat capacity of the heat-absorbing material of the box body.

• ΔT is the temperature change of the item.

• t is the heating time.

4.The power needed for exhaust air energy consumption:P4=ρ*Q2*CΔT2/t

• Q2 is the exhaust air volume: Q2 = V * S, (V is the fan exhaust velocity, S is the cross-sectional area of the exhaust port).

• ρ is the density of air (at standard atmospheric pressure, room temperature air density of about 1.225kg/m3 meters).

• C is the specific heat fusion of the air, multiplied by ΔT for the temperature change of the items.

• t for the heating time.

5.The box heat loss of power required P5

Calculation of box heat loss, need to consider the sealing effect of the Oven, box size and other factors, due to these factors is difficult to calculate accurately, generally estimated according to the actual situation, usually 1 to 4 items of the total power of 10% to 30%% or so.

6.through the above calculations can be obtained oven heating power: P = P1 + P2 + P3 + P4 + P5

7.in the actual application, but also need to take into account the heating mode of the oven, heating medium, heat conduction and other factors. Different heating methods will have an impact on the heating power of the oven, so these factors need to be considered when calculating the heating power of the oven.
