HeatMatrix - Thermal Oil Heaters
Cold spot corrosion problems limit heat recovery. The polymer air preheater is corrosion resistant and can boost your Thermal Oil Heater efficiency.
Thermal Oil Heaters are applied in the industry where such high temperatures are required that can not be generated with steam. They are reliable systems because you do not have to deal with high pressures, water treatment and condensate losses that typically exist when you operate a steam boiler. However most installed Thermal Oil Heaters tend to have a low thermal performance, in the range of 85 to 90%.
All fuels contain acidic elements. When you burn the fuel and cool flue gas too deep, then – depending on the fuel type – the acidic elements will become corrosive and the installed heat exchangers will suffer from cold spot corrosion due to the relatively cold metal surface temperatures. This limits heat recovery. If you can prevent this problem, enhancing further thermal efficiency is possible. This results in extra energy savings.
The simplest and most economical way to improve the efficiency of your Thermal Oil Heater is by applying combustion air preheating. The heat from the flue gases is recovered and used to preheat the cold combustion air entering the burner. Hot air is burned which means that you need less fuel to achieve a certain duty. A polymer air preheater of HeatMatrix enables heat recovery to a flue gas temperature of less than 100 ºC and can boost heater efficiencies to 95% and higher.
The polymer air preheater can be installed in series with a metal air preheater to recover heat over a very broad temperature range and ensures a reliable operation. If you already have a metal air preheater on your Thermal Oil Heater, the addition of a polymer air preheater will further boost efficiency.
The polymer air preheater protects the metal air preheater for local corrosion and the metal air preheater protects the polymer air preheater for high temperatures. The polymer air preheaters of HeatMatrix are suitable for flue gas coming from burning any kind of fuel ranging from natural gas to fuel oil.
