CATVAP – Catalytic Vaporiser Burner
Together with the Fraunhofer Institute for Solar Energy Systems in Freiburg and another industrial partner, we’re developing a premixing line burner for liquid fuels. In a catalytic process arranged before combustion, some of the combustion air is used to trigger a preliminary fuel reaction. The resulting heat inside the catalytic converter completely vaporises the fuel. After the remaining combustion air is mixed in, the whole mixture is combusted using a conventional line burner. As a result, it’s possible to employ the equipment platform used for condensing boilers for liquid fuels as well. This is particularly advantageous due to the heating equipment’s high modulation range, low emissions, reduced lower performance limit, low noise level and compact construction.
High-Modulating Burners (Oil/Gas) for Compact Fireboxes in Heat Pumps
The massive reduction in CO2 emissions from buildings is one of the most important goals of climate policy. Our central approach is to significantly reduce specific CO2 emissions (decarbonisation) from heating technologies. Besides electrically-driven heat pumps, thermally-driven heat pumps are also a sensible alternative, especially for existing buildings.
For large-scale development of the heating market with thermally-driven heat pumps, high feed temperatures (>50°C) are just as important as the quick loading of hot water tanks. According to the present state of development, such heat pumps can achieve coefficients of performance totalling >1.5 in existing buildings.
To achieve this goal, we have been part of a research project together with the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg and other industrial partners. In this field, we are also cooperating directly with heat pump providers.
