A revolutionary technology leap
The HeatCore product is the heart of a gas-fired boiler, where it converts the energy in the fuels to produce hot water for space heating and tap water. This is an efficient process, and a technology that has been used and refined over a long time. The industry, however, saw a major technology leap when it went from atmospheric combustion to condensing boilers in the late 1990s. And now it’s time for the next big leap: the HeatCore hybrid combustion method.
Achieving unique compactness through hybrid combustion
The HeatCore product concept builds on two unique foundations: the HeatCore burner technology with its hybrid combustion method, HAHC (heterogeneously assisted homogeneous combustion), and a heat exchanger optimally complimenting the combustion process.
Depending on the energy flux, different modes of combustion are possible on a wire-mesh catalyst. In order to achieve extremely high energy fluxes, the combustion in the HeatCore units is performed in the hybrid mode. Here, the catalyst generates reactive species – free radicals – from fuel, water and oxygen by a thermo-catalytic reaction. Thus time and temperature for the combustion are reduced as the radicals react with fuel molecules downstream of the catalyst in the gas phase.
Hybrid combustion offers a great advantage over conventional flame combustion: the process requires less space. This technology makes it possible to reduce dramatically the combustion space of the burner and drive down the emission levels to zero.
A concept build for long duration
The second foundation in the HeatCore product concept is the heat exchanger. The unique design leads to heat transfer coefficients which are very high indeed giving high energy flux. The result is lower volume with peak efficiency of up to 109% and a combustion process that approaches zero emissions.
The unique outcome for the heat exchanger is how we have developed and customized it to work optimally with the hot gases. Due to a unique flow principle harmful effects on metal surfaces exposed to hot gases are simply prevented. This way we manage to avoid thermal fatigue phenomena risks. These risks are further reduced by choice of construction materials and the way we join the components in the heat exchanger together.
We also choose materials that can handle the condensate that is produced during operation, as well as a welding method that does not require any extraneous material. All this makes the HeatCore unit insensitive to thermal fatigue and corrosion.
Both the technology and the design are well protected by a series of patents.
