I'm not new to coal or clinkers but the question recently came up of the temperature of a home heating appliance. Obviously it's hot enough inside the fire box to cause formation of clinkers. AKA melted silica, iron etc etc .
I have read the temperature of the heating appliance should not exceed 700°F but nobody mentions what component(s) this warning is in reference to.
If the burning of coal within a home heater forms clinkers, at what temperature does clinker form?
If I place a steel fire tool into the firepot of my home heater, the 1/2" round steel will quickly reach 1,200°F thusly its obviously well over 1,000° inside the firepot/firebox.
We routinely heat our steel in the blacksmith shop to 2,500° with a coal fire but push a fair amount of air into it to achieve a 3,000° fire. Thusly the formation of clinker is a given.

For a radiant stove that generally refers to the temperature of the stove body.
