About Heat Recovery Systems
Heat recovery is a valuable way to reuse otherwise “lost” energy to reduce overall running costs.
Waste heat from a process can be used to reduce a sites heating requirements, either for another process, or for general heating and hot water by the use of an additional heat exchanger on the main cooling circuit. This has the dual advantage of reducing heating costs, and those of the cooling system, as the cooling requirement is at least partially performed by the heat recovery system.
Denco Fluid Systems can design, supply and install heat recovery systems for a number of different applications such as: water cooled condensers, flue gas, air compressors and steam plants.
A Water-Cooled Condenser is a heat exchanger that removes heat from refrigerant vapour and transfers it to the water running through it.
In doing so, the vapour condenses and gives up heat to the water. Applications include wash down water pre-heating, process heating and boiler return water pre-heat.
Flue Gas Heat Recovery Systems are designed to recover energy from flue gases or process air and transfer this thermal energy to a water system which can then be exported to another point of use. In a market with ever increasing energy prices there is a focus on effective use of resources and reduction of CO2 gas emissions. It therefore makes sense to exploit the considerable amounts of energy found in flue gas, steam or other process heat exhaust and extraction systems for heating of steam system make-up water, space heating / central heating, combustion air pre-heating and electrical generation (organic rankine cycle, steam turbine or expanders}.
Approximately 90% of the electrical input to an air compressor is lost as heat. By recovering this waste heat energy from air or water-cooled compressors you can reduce energy bills significantly and thus can reduce CO2 emissions. The thermal energy recovered can be recovered to an air or water system and be utilised in many different ways.
