Abstract
A distribution ring for fuel in a burner (7) includes a hollow body (21) which is configured to be annular with respect to a longitudinal axis (22), a feed spigot (23) which is connected to the hollow body (21) and is intended for feeding the fuel into the hollow body (21), and a plurality of discharge spigots (25) for discharging the fuel from the hollow body (21) to the burner (7). The discharge spigots (25) are each arranged externally at the hollow body (21) in the radial direction of the longitudinal axis (22).
Claims18
A distribution ring for fuel comprising solid particles in a burner, wherein the solid particles of the fuel are fed into said distribution ring by means of compressed air, the distribution ring comprising:
- a hollow body which is configured to be annular with respect to a longitudinal axis;
- a feed spigot which is connected to the hollow body for feeding the fuel into the hollow body;
- and
- a plurality of discharge spigots which are configured to discharge fuel from the hollow body to the burner, wherein each of the plurality of discharge spigots is arranged externally at the hollow body in a radial direction of the longitudinal axis, wherein the hollow body has a polygonal inner contour in a sectional plane containing the longitudinal axis, wherein an outer edge, oriented with respect to the radial direction, is oriented at least in sections parallel to the longitudinal axis.
A distribution ring for fuel comprising solid particles in a burner, wherein the solid particles of the fuel are fed into said distribution ring by means of compressed air, the distribution ring comprising:
- a hollow body which is configured to be annular with respect to a longitudinal axis;
- a feed spigot which is connected to the hollow body for feeding the fuel into the hollow body;
- and
- a plurality of discharge spigots which are configured to discharge fuel from the hollow body to the burner, wherein each of the plurality of discharge spigots is arranged externally at the hollow body in a radial direction of the longitudinal axis, wherein the hollow body has an axial extension that is oriented parallel to the longitudinal axis and is variable in a circumferential direction with respect to the longitudinal axis.
A burner comprising:
- an air supply;
- a fuel feed configured to feed a fuel comprising solid particles;
- and
- a distribution ring connected to the fuel feed wherein said solid particles are fed into the distribution ring by means of compressed air from the air supply, the distribution ring comprising:
- a hollow body which is configured to be annular with respect to a longitudinal axis;
- a feed spigot which is connected to the hollow body for feeding the fuel into the hollow body;
- and
- a plurality of discharge spigots which are configured to discharge fuel from the hollow body to the burner, wherein each of the plurality of discharge spigots is arranged externally at the hollow body in a radial direction of the longitudinal axis, wherein the hollow body has a polygonal inner contour in a sectional plane containing the longitudinal axis, wherein an outer edge, oriented with respect to the radial direction, is oriented at least in sections parallel to the longitudinal axis.
A burner comprising:
- an air supply;
- a fuel feed configured to feed a fuel comprising solid particles;
- and
- a distribution ring connected to the fuel feed wherein said solid particles are fed into the distribution ring by means of compressed air from the air supply, the distribution ring comprising:
- a hollow body which is configured to be annular with respect to a longitudinal axis;
- a feed spigot which is connected to the hollow body for feeding the fuel into the hollow body;
- and
- a plurality of discharge spigots which are configured to discharge fuel from the hollow body to the burner, wherein each of the plurality of discharge spigots is arranged externally at the hollow body in a radial direction of the longitudinal axis, wherein the hollow body has an axial extension that is oriented parallel to the longitudinal axis and that varies in a circumferential direction with respect to the longitudinal axis.
A drying drum comprising a burner, the burner comprising:
- an air supply;
- a fuel feed configured to feed a fuel comprising solid particles;
- and
- a distribution ring connected to the fuel feed wherein said solid particles are fed into the distribution ring by means of compressed air from the air supply, the distribution ring comprising:
- a hollow body which is configured to be annular with respect to a longitudinal axis;
- a feed spigot which is connected to the hollow body for feeding the fuel into the hollow body;
- and
- a plurality of discharge spigots which are configured to discharge fuel from the hollow body to the burner, wherein each of the plurality of discharge spigots is arranged externally at the hollow body in a radial direction of the longitudinal axis, wherein the hollow body has a polygonal inner contour in a sectional plane containing the longitudinal axis, wherein an outer edge, oriented with respect to the radial direction, is oriented at least in sections parallel to the longitudinal axis.
