Considerations for Explosion-Proof Electric Heaters - Yangzhou Darui
Darui Electric recommends for you
The calculation of heating power includes the following three aspects:
● Power during operation ● Power during startup ● Heat loss in the system
All calculations should consider the worst conditions:
● Low ambient temperature ● Short operating cycle
● High operating temperature ● Large weight of heating medium (large flow rate for flowing medium)
Steps for calculating heater power
● Based on the process, draw the process flow diagram for heating (does not involve material form and specifications).
● Calculate the heat required for the process.
● Calculate the heat and time required for system startup.
● Redraw the heating process flow diagram, consider an appropriate safety factor, and determine the total power of the heater.
● Determine the sheath material and power density of the heating element.
● Determine the heater form, size, and quantity.
● Determine the power supply and control system of the heater.
