First, the design calculation of the heating pipe is generally carried out in the following three steps:
(1) Calculate the required power to heat from the initial temperature to the set temperature within the specified time
(2) Calculate the actual required temperature to maintain the temperature while maintaining the temperature of the medium unchanged.
(3) According to the above two calculation results, select the type and quantity of the heater. The total power takes the maximum of the above two powers and considers the 1.2 coefficient.
formula:
1. Power required for initial heating KW = ( C1M1T + C2M2T ) ÷ 864/P + P/2
Where: C1C2 is the specific heat of the vessel and medium (Kcal/Kg°C)
M1M2 is the mass of the container and medium (Kg)
T is the difference between the required temperature and the initial temperature (°C)
H is the time required to heat the initial temperature to the set temperature (h)
Heat dissipation of the container at the final temperature of P (Kw)
