I want build a furnace using firebricks and coiled nichrome wire. The dimensions of the furnace are 1×1×1 m. I need temperature inside the furnace to be 650°c. I have 220 VAC mains.
The furnace will be insulated with ceramic insulation plates and closed very well using a metal door. The heat can build up slowly.
It will used for drying Biomass and woods. The material will be placed into the cold furnace, then brought up to temperature for a time, then allowed to cool.
Now my questions are:
- What is the suitable type and thickness for the nichrome wire?
- What is the proper length of the coiled nichrome wire to get 650°c ?
- If I will use electricity generator to supply the furnace with electricity , how many kilo watt the generator should generate to supply this furnace? Thank you
