tubular heating element heaters Power calculation formula method

1. Calculate the power required to heat up to the set temperature from the initial temperature within a specified time

2, calculated to maintain the same medium temperature, the actual need to maintain the temperature of the power

3, according to the above two results, select the heater model and quantity. The total power takes the maximum value of the above two kinds of power and considers 1.2 coefficient.

formula:

1, the initial heating required power KW = (C1M1T + C2M2T) ÷ 864 / P + P / 2

Where: C1C2, respectively, for the container and the specific heat (Kcal / Kg ℃)

M1M2 is the mass of container and medium (Kg)

T is the difference between the required temperature and the initial temperature (C)

H is the time required for the initial temperature to be heated to the set temperature (h)

(KW) of the container at the final temperature

2, to maintain the power required for medium temperature pumping KW = C2M3T / 864 + P

Where: M3 per hour of increased media kg / h


Add: No. 16, Road 3, Sanjiang Industry Zone, Shengzhou, Zhejiang, China
