Energy recovery solutions

Industrial cooling systems include various possibilities to catch waste heat that is in normal conditions ventilated to atmosphere either through dry-coolers or cooling towers located on the roof of building. Instead of using direct electrical energy-driven cooling equipment, why not use a heat pump so that the recovered heat can be used in building heating, domestic hot water or somewhere else directly in the production. 

One of the most common mistake a steam system operator does, is not using the full potential of condensate. When allowing condensate to drain directly to the drainage, we automatically loose the energy and effort we have put into it. Condensate = water, energy, water treatment chemicals and salts, service. Do not allow this highly resourceful process leave your factory. Besides just re-using by returning condensate, there are also alternative ways to capture all excess heat contained – recovering flash steam from condensate, using the thermal energy from contaminated condensate and many more.

When pressurized condensate is released to lower pressure, for an example atmospheric pressure, it will start to evaporate meaning you will now have both condensate in liquid form and steam in gaseous form in the pipeline or in a vessel. Typically this flash steam is vented through ventilation piping but it does not have to be like this. There is a possibility to catch this steam and send it back to the system – this can be done using a heat exchanger, a special flash steam condenser or many more options.

We can offer different solutions to catch waste heat in flue gases before entering the chimney. This can be done either with a simple econmizer or exhaust gas boiler. Flue gas economizer is basically a special heat exchanger solution that is design to fit your specific needs – room requirements, existing boiler and burner construction and design, materials in use and process where to put the heat.

Economaizers can be installed to a steam boiler and as well as a hot water boiler. Economizer can be done in different phases, meaning that even if you already have ‘hot eco’ available, there is always room for more.

Flue gases can be lowerer even up to 40°C, capacity vise there is no restrictions.

Most of industries use compressed air to run actuators and operate directly the processes. Air compression system uses lots of electrical energy and during the process there is created lot’s of excess heat that is not used smartly. Usually the waste heat from compression process is cooled down outside using atmosphere air using either dry coolers or cooling towers. There is a solution how to send the excess heat from compressor oil or air back to the factory – using this to preheat the process, rooms of factory itself or hot domestic water.

Heat recovery can be something very simple and coming straight from the process of your specific industry. It is quite everyday life in a factory when simultaneously there is a need for preheating, main heating and cooling cycles for the product. Why not put the entire process work together smartly and efficiently? Why not use the waste energy in the product cooling phase by pre-heating some other part of the process? All of this is very case-dependant and needs to be tailor-design with each case but in general the mindset of this is to create a unique solution in the means of sector-coupling inside the factory.
