Superheated steam - Import export

In cases where waste liquid’s or suspension’s need to be incinerated, EUROPEM uses liquid fuel injection lances equipped with ultrasonic atomisation nozzles, resulting in very fine droplets and an almost gas-like combustion process. This nozzle uses an atomizing fluid such as superheated LP steam or compressed air. EUROPEM Natural Draft and Forced Draft Burners Different configurations for the atomization nozzle are possible, depending on the burner design, capacity range and the desired spray pattern in relation to the combustion chamber. The nozzle operates based on the Hartmann Generator principle and was originally developed the early 1970s. In 2007, the nozzle was optimized and now has a fuel turndown ratio of 10:1. Hartmann Generator principle: Through a jet nozzle (D), a gaseous fluid flows with supercritical pressure ratio – meaning sonic speed. According to Mach and Salcher a periodical structure will build up in the stream (dotted line). Graph K shows the pressure cycles along the length of the gas stream. Oscillations occur by filling (pressurizing) and deflating the hollow space H. This is the principle used for the Ultrasonic Nozzle. A Hartmann Generator is placed as a concentric ring around a central liquid fuel pipe. The high exit speed of the atomizing fluid (compressed air, steam or combustible gas) alone achieves a rough atomization, caused by the negative pressure. The ultrasonic effect created by the Hartmann Generator oscillates the pre-atomized droplets at a high frequency, and further fragments the droplets into a very fine mist. Advantages: Low and high viscosity fluids are atomized into smallest possible droplets. No limitation on ash content and other solid particles in liquid fuels. Various fuel types can be used in one nozzle, no limitation on fuel mixtures. High durability due to low operating pressure for fuel and atomizer. Different nozzle types to obtain different spraying paterns
