A burner that includes a primary air or gas duct delimited by an exterior wall and a concentric interior wall of axis X and ducts for radial primary air or gas injection is described. The air or gas duct includes a ring that is rotationally mobile and has axial protrusions constituting distributors which collaborate with the radial primary air ducts arranged on the interior wall and form two passages of different angles in each duct. Rotating the ring making it possible to vary the angle of injection of the radial primary air. Thus, the regulation is situated just at the tip of the burner, in the region of the outlet of the primary air into the kiln, by modifying the outlet angle of the radial component for fixed section, thereby greatly simplifying the regulating of the burner.

A fire safety protection evaluation system includes at least one horizontal collection device and at least one vertical collection device. The at least one horizontal collection device includes a liquid collection pan with a substantially horizontal opening, a first storage container in communication with the liquid collection pan, and a first measuring device to measure an amount of liquid in the first storage container and/or a rate of liquid entering the first storage container. The at least one vertical collection device includes a substantially vertical liquid collection surface extending between a top edge and a bottom edge, a trough located along the bottom edge to collect liquid from the substantially vertical collection surface, and a second measuring device to measure an amount of liquid and/or a rate of liquid collected by the trough.

A multistaged lean prevaporizing premixing fuel injector apparatus is provided. The fuel injector may be utilized with a turbogenerator. Preheated combustion air from the turbogenerator's recuperator may be utilized by the fuel injector to prevaporize liquid fuel. The injector may provide for premixing of multiple fuel streams and include multiple stages with a flow distributor plate separating adjacent stages. The injector may include multiple stages, with a pilot tube located in a final stage splitting the fuel stream into a premixed pilot stream and a premixed final fuel and air mixture stream.

An object of the present invention is to provide a combustion burner that is capable of efficiently performing heating of a raw material powder by improving the dispersibility of the raw material powder that is ejected from a raw material powder-ejecting port using a simple configuration, and a combustion burner in which raw material powder introduction pipes that introduce the raw material powder inside a raw material powder supply pathway are provided so that axes that extend from central axes of the raw material powder introduction pipes do not intersect a central axis of the burner main body, and so that angles that are formed by central axes of the raw material powder introduction pipes and an outer surface of a second circular member are larger than 0 and smaller than 90.
