An example of a species collection system includes a plurality of spaced-apart electrically conductive collectors and a plurality of emitter electrodes. In some embodiments, at least one emitter electrode is disposed between adjacent ones of the collectors. In some embodiments, the at least one emitter electrode extends beyond the collectors (e.g., in at least one dimension). Collectors may be aligned to a direction of gas flow from an outlet (e.g., of a cooling tower) to facilitate collection while minimizing interference with the gas flow. Different emitter electrodes may be maintained at different voltages. In some embodiments, collectors are attached to a collector frame and emitter electrodes are attached to emitter frame(s) that are electrically insulated from the collector frame. Collectors may span a gas outlet (e.g., of a cooling tower) and emitter frame(s) may be positioned outside of the collectors (e.g., and outside of a periphery of the gas outlet).

A grilling machine is described, which comprises a base body, a plate, arranged on the base body and defining a cooking surface whereon foods to be cooked are laid, and heating means operationally associated with the plate for heating the cooking surface. There is also a circuit, associated with the plate, for treating the fumes produced during the food cooking process. The fumes treatment circuit comprises: a hood arranged above the plate, which comprises at least one suction mouth, a filtering unit fluidically connected to the hood, and at least one recirculation outlet fluidically connected downstream of the filtering unit and located near the plate. In this manner, the cooking fumes sucked in through the suction mouth of the hood are treated by the filtering unit in order to obtain a purified flow with a given percentage of humidity. The purified flow is then recirculated towards the cooking surface through the recirculation outlet in order to exert a humidifying action on the foods.

Provided are purification systems and methods of using such systems for purifying various environments, such as indoor air, outdoor air, vehicle emissions, and industrial emissions. A purification system comprises an ionizing purifier having a substrate and an active coating. The active coating comprises a pyroelectric and/or piezoelectric material. During the operation, an incoming stream is directed toward the active coating while controlling the average pressure exerting on the active coating. This contact between the incoming stream and the active coating generates negative ions from components of the incoming stream via change in temperature and pressure/force/vibration, etc. The negative ions then interact with pollutants, transforming them into safe, purified materials of the outgoing stream. Unlike the pollutants in the incoming stream, the purified materials are non-harmful, and/or can be easily removed from the outgoing stream, e.g., by filtering and/or other separation techniques.

The pulse firing pattern for a transformer of an electrostatic precipitator comprises first elements indicative of a pulse to be fired and second elements indicative of a pulse to not be fired. The pulse firing pattern further comprises couples of adjacent second elements and at least two first elements.
