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
Turnkey complete solution for integration in your production
