A nebulizer for atomizing a high-temperature liquid includes a truncated, conical concentrator that defines a vertex and that has a small-diameter end and a large-diameter end. The small-diameter end has a spherical-shaped, concave surface and the large-diameter end has a spherical-shaped, convex surface. A piezoelectric transducer has a spherical-shaped, concave surface that is attached to the convex surface of the concentrator. A cylindrical-shaped droplet manifold is positioned over the small-diameter end of the concentrator to create a liquid chamber in the manifold with the vertex inside the liquid chamber. A feeding tube introduces the high-temperature liquid into the liquid chamber until the surface of the liquid reaches the vertex. With an activation of the transducer, acoustic waves that have spherical wavefronts are launched away from the concave surface of the transducer. The concentrator propagates and directs the spherical wavefronts for convergence at the vertex to nebulize the liquid.
