When a solid is heated above its melting point, it melts and becomes liquid. By spraying this, it is transformed into many fine particles. By applying cold air to these particles and solidifying them, spherical products are obtained. By selecting the spray conditions, the product size can be set in the range of several microns to several thousand microns. Additionally, by mixing another substance that serves as a core into the melted material and applying the same treatment, microencapsulation can also be achieved. ● For more details, please contact us or download and view the catalog.

GASTEM is a system that primarily uses an instant cooling device to treat exhaust gases generated from general waste incinerators and industrial waste incinerators. It combines harmful gas removal devices and dust collection devices to adsorb and recover dioxins and other harmful substances from various exhaust gases, ensuring that emissions are below regulatory limits. In particular, the instant cooling tower incorporates liquid atomization and drying technology (spray & dry), enabling complete evaporation of the sprayed liquid, prevention of fly ash adhesion, and uniform exhaust gas temperature, which allows for stable continuous operation.

The key point in dioxin countermeasures is to instantaneously cool high-temperature exhaust gases to below 200°C. The nozzle must be capable of "allowing for the complete evaporation of water droplets in the cooling tower" and "creating fine droplets of less than 100 microns." This is only possible with a high gas-to-liquid ratio two-phase nozzle. A new energy-efficient, high-performance pressurized two-phase nozzle has made the impossible possible. ● For more details, please contact us or download and view the catalog.
