The design calculation of a single head heating tube generally follows the following three steps:
1. Calculate the power required to heat from the initial temperature to the set temperature within the specified time
2. Calculate the actual power required to maintain the temperature of the medium while maintaining it constant
3. Based on the above two calculation results, choose the model and quantity of the heater. Take the maximum value of the above two types of power for the total power and consider the coefficient of 1.2. Formula:
1. The power required for initial heating of a single head heating tube, KW=(C1M1T+C2M2T) ÷ 864/P+P/2, where C1C2 represents the specific heat of the container and medium (Kcal/Kg ℃), respectively
M1M2 represents the mass of the container and medium (Kg), T represents the difference between the required temperature and the initial temperature (℃), H represents the time required for the initial temperature to be heated to the set temperature (h), and P represents the heat dissipation of the container at the final temperature (Kw)
2. The power required for maintaining the medium temperature of a single head heating tube is KW=C2M3T/864+P, where M3 increases the medium kg/h per hour
