The hyperbolic hollow cone nozzle from Engine & Balsamico Design compared to other nozzles that are on the market is characterised by the fact that at a given pressure it provides a finer spray with very even-drop size distribution. Such a monodisperse spray produces a larger surface area per unit volume used, i.e. a higher number of drops which ultimately improves the probability of a reaction in chemical and physical processes. Such uniform and reproducible spray patterns support the accuracy of many complex applications such as those used in biotechnology. The considerably lower drop velocity compared to conventional nozzles allows for a longer reaction time. The pneumatic atomiser nozzle offers advantages over current ‘state of the art’ nozzles – key features of the two-substance nozzle from Engine & Balsamico Design are: reduced compressed gas consumption, even-droplet size distribution and a lower noise level. In our prototype laboratory we can quickly create a tailor-made nozzle concept for your individual application and can offer a comparative spray pattern analysis.
The increasing demands on exhaust gas quality require optimised combustion which is achieved by the enlargement of the surfaces and thus the reaction areas. Here too the hyperbolic hollow-cone nozzle and the pneumatic atomizer nozzle from Engine & Balsamico Design exceed the state of the art in atomizing liquid fuels from a flow rate of 0.2 GPH. In addition to complete combustion, lowest NOx values are achieved by a uniform droplet size distribution and a very low droplet velocity. For the optimal combination of the reaction partners, Engine & Balsamico Design is working on a novel combustion chamber principle called ma.rs.one.
The pneumatic atomizing nozzles are arranged on a hyperbolic combustion chamber in such a way that a double helix flow can be realised for an optimised combustion efficiency at very low NOx values. This idealised and variable fuel and air supply also ensures an optimised combustion chamber temperature.
The most efficient way to achieve a mixture of two or more fluids in a very small space is to guide the fluids along a double helix path, i.e. a spiral flow winding along a spiral. Our start-up has already been able to demonstrate this in the mixing of fuel and oxidiser – as well as water and compressed air in technical snowmaking. The applications for a fluid mixing device in process engineering are many. The team is currently developing a device for the efficient gassing of water with oxygen for laboratory applications.
Separation(gas- and hydrocyclones)
In mechanical process engineering, gas- and hydrocyclones are a common and cost-effective method for separating moisture, dust, soot, droplets and isotopes. For example, this technology is also used in bagless vacuum cleaners. However, the separation efficiency often does not meet the requirements, which is why membrane processes are widely used. The separation in the centrifugal field is much more robust and by means of hyperbolic geometries as they occur in the free flow field, for example hurricanes, the pressure difference between the centre (eye) and the peripheral zones is maximised and optimal separation results are achieved, which compete with membrane processes. The most important efforts in this field concern gas separation from liquids and the separation of soot particles from diesel engine exhaust gases for new types of exhaust gas measuring instruments.
