Heat Recovery - Or How To Afford Yourself a New Mercedes Every Year

 

Who would not like to know how it would be possible to afford a new Mercedes every year, solely through the savings by a heat recovery system? In other words, you can also call it "reduced production costs".

This increases the cost efficiency of your production and thus increases the competitiveness of your products. In addition, recovering waste heat can also generate significant cost savings, help saving fossil energy and therefore protect the environment for our children.

Almost every week, you can expect news about rising energy costs. Many efforts are being made in industrial operations to reduce energy consumption of the production. Most companies invest in better and more efficient production machines, high- efficient electric motors and LED lighting, even though the results of this type of saving are often not impressive and the costs are high. Not many are aware of how much energy can actually be saved by replacing fossil fuels with the recovery of existing heat.

Many industrial processes, ovens, engines or high temperature process heaters (thermal oil heaters or steam boilers) release waste heat on a high temperature level to the atmosphere. This is very unfortunate, since the energy can not only be used to generate process heat, but also to generate electrical energy, or even chilled water.

The value of the saved fossil fuel is often easily equal to the value of a pretty nice Mercedes Benz car. Therefore, the result shows impressive payback and ROI numbers.

We have installed quite a lot of heat recovery systems during the last decade, in various industrial operations. In most of the cases, the investment for this kind of system is manageable and the amortization is done in a few years.

This calculation neither includes the future increasing costs for fossil fuels, nor does it include the significantly reduced maintenance costs, compared to burners or furnaces for fossil fuels.

In the following we want to give you a few examples for different heat recovery concepts.

 

Example 1, Thermal Oil Heater for process heat supply

Fuel Natural Gas (US$ 10,-/mmbtu = US$ 0,32/m³), heating value 9,5kWh/m³, operation 8000h / Year, Heat use: Pre-heating of the combustion air

Example 1, Thermal Oil Heater for process heat supply

Example 2, Heat Recovery from Gas Engines in a Tapioka Production

Fuel: Coal, heating value 3500kcal/h (4,1kW), Efficiency, coal fired heater 76%, heat use: Process heat for flash dryer, Heat Recovery from 3 Biogas Engines 1.800kW, operation 8000h/Year

Example 2

The enormous cost savings for reduced electricity consumption and maintenance costs for the furnace is not even calculated!

 

Example 3, Heat Recovery from a drying channel for plastic foil

Fuel Natural Gas (US$ 10,-/mmbtu = US$ 0,32/m³), heating value 9,5kWh/m³, operation 8000h / Year, Heat use: Pre-heating of the drying air

Example 3

The savings in the last example may not be as remarkable as in example No. 1 and 2, and also may not be enough to buy a new Mercedes every Year, but it still helps to reduce the production costs and it is also not too bad to have a payback of less than 2 years – Keep in mind that rising energy costs can also increase the potential savings.

Impressed? In most of the industrial productions there is a useful waste heat potential. If not, there are still other production residues, which could also potentially lead to energy savings.
