An insulated solution injector may include an outer tube and an inner tube arranged within the outer tube. The outer tube and the inner tube may define an annular space therebetween, and the inner tube may define a solution space within. The annular space may be configured so as to insulate the solution within the solution space. As a result, the solution may be kept to a temperature below its decomposition temperature prior to injection. Accordingly, the decomposition of the solution and the resulting deposition of its constituents within the solution space may be reduced or prevented, thereby decreasing or precluding the occurrence of a blockage.

An inlet assembly for an abatement apparatus includes an inlet nozzle defining a non-circular inlet aperture coupleable with an inlet conduit providing an effluent gas stream for treatment by the abatement apparatus, at least one outlet aperture and a nozzle bore extending along a longitudinal axis between the non-circular inlet aperture and the outlet aperture for conveying the effluent gas stream from the non-circular inlet aperture to the outlet aperture for delivery to a treatment chamber of the abatement apparatus, the nozzle bore defining an inlet portion extending from the non-circular inlet aperture, a flow-dividing structure positioned downstream of the inlet portion and configured to separate the effluent gas stream into at least a pair of effluent gas streams and an outlet portion extending to the outlet aperture and configured to convey the pair of effluent gas streams to the treatment chamber of the abatement apparatus.

A burner module according to the invention comprises at least three or four or five or six or seven or eight functional walls which delimit at least one first functional space and form a module body, wherein the module body has at least three or four or five or six or six or seven gas passage openings and at least two of these gas passage openings are connected to one another communicatively via the first functional space, and wherein at least one nozzle device having a fuel gas opening is formed in an upper wall of the burner module, which fuel gas opening is connected communicatively to the first functional space via a gas channel. The burner module is produced in an additive manner.

A method for collecting particles or gaseous chemicals is provided. The method includes providing liquid to a tube of a droplet generator, heating, with a heater of the droplet generator, the tube to provide vapor to a gas flow channel inside the tube, passing a gas flow containing the particles or gaseous chemicals through the gas flow channel inside the tube to obtain droplets including the particles or gaseous chemicals, and passing the droplets including the particles or gaseous chemicals to a wall of a collecting device such that the droplets including the particles or gaseous chemicals hit the wall. The temperature inside the gas flow channel is higher than a temperature inside the collecting device.

The invention discloses a method and modified aerodynamic apparatuses: fluid pushers-off and fluid motion-sensors, making enable efficient implementation and use of a controllable enhanced jet-effect, either the waving jet-effect, the Coanda jet-effect, the lift-effect, the effect of thrust, the Venturi effect, and/or the de Laval jet-effect, all are controllable using the Peltier effect and/or the Seebeck effect.
