High operating temperatures?
Molten salts as heat transfer media
1. Heater with burner // 2. Combustion air preheater // 3. Combustion air fan // 4. Chimney // 5. Salt pump // 6. Salt tank, heated // 7. Heat consumer
With molten salts as heat transfer media, operating temperatures well beyond 500 °C can be realized. For applications, in which high temperatures are required – such as the production of melamine or aluminum oxide or the sodium or potassium hydroxide evaporation – molten salts are the first choice as heat carrier.
Molten salts are a eutectic mixture consisting of potassium nitrate, sodium nitrite and sodium nitrate having a melting point of 142 °C. Under operational conditions they are liquid and are operated unpressurized.
This is what you can expect from our heat transfer plants with molten salts:
Well beyond 500 °C of useful operating temperature
Operating safety by self-draining systems
Optimum heat utilization by three-pass boilers
Highest efficiency and low emissions by air preheating and waste gas recirculation
Top and bottom fired vertical boiler designs are available
