Support assembly for a boiler

A support assembly for supporting a furnace of a boiler to a support frame of the boiler,

• wherein the furnace comprises four vertical, planar water tube walls which are joined together and which, in a horizontal plane, define a rectangular cross section with four corner sections, two of the water tube walls being joined in each corner section, the four corner sections including a first corner section at which a first water tube wall and a second tube wall that are transverse to each other are joined,
• wherein the boiler further comprises at least one vertically extending pipe that is for the transport of water and/or steam and situated outside the furnace, the pipe being close to the first corner section, and
• wherein the support frame further comprises:
• at least two horizontal supporting beams that are separated from the water tube walls and include a first supporting beam and a second supporting beam that are transverse to each other, and
• a connecting supporting beam that is oblique in relation to the first and second supporting beams, that is separated from the water tube walls, and that comprises:
• a first end attached to the first supporting beam, or to a third supporting beam that is supported by the first supporting beam or by the second supporting beam, and
• a second end attached to the second supporting beam, or to a fourth supporting beam supported by the second supporting beam, and
• wherein the support assembly close to the first corner section comprises:
• a first assembly part that comprises a first suspension device and attaches the pipe to the oblique connecting supporting beam,
• wherein the first suspension device provides, at the oblique connecting supporting beam, a first point of support where loads incurred by the weight of the pipe and the furnace attached to the pipe are transmitted to the oblique connecting supporting beam, and
• wherein the first suspension device is configured to suspend the pipe from the oblique connecting supporting beam, and
• a second assembly part that comprises a second suspension device and attaches the same pipe to the oblique connecting supporting beam,
• wherein the second suspension device provides, at the oblique connecting supporting beam, a second point of support where loads incurred by the weight of the pipe and the furnace attached to the pipe are transmitted to the oblique connecting supporting beam, and
• wherein the second suspension device is configured to suspend the same pipe from the oblique connecting supporting beam.

• wherein the support assembly close to the first corner section comprises
• a first assembly part that comprises a first supporting leg and attaches the pipe to the first supporting beam, or to a third supporting beam that is supported by the first supporting beam or by the second supporting beam,
• wherein the first assembly part defines, at the first supporting beam or at the third supporting beam, a first point of support under the first supporting leg on the first supporting beam or the third supporting beam, the first point of support being where loads incurred by the weight of the pipe and the furnace attached to the pipe are transmitted to the first supporting beam or to the third supporting beam, and
• wherein the first supporting leg is supported on the first supporting beam or the third supporting beam and provides the first point of support, and
• a second assembly part that comprises a second supporting leg and attaches the same pipe to the second supporting beam, or to a fourth supporting beam that is supported by the second supporting beam,
• wherein the second assembly part defines, at the second supporting beam or at the fourth supporting beam, a second point of support under the second supporting leg on the second supporting beam or the fourth supporting beam, the second point of support being where loads incurred by the weight of the pipe and the furnace attached to the pipe are transmitted to the second supporting beam or to the fourth supporting beam, wherein the second supporting leg is supported on the second supporting beam or the fourth supporting beam and provides the second point of support, and
• wherein the first and second assembly parts including the first and second supporting legs are oblique in relation to the first and second supporting beams in such a way that:
• the first point of support is farther away from the second supporting beam than the pipe when viewed in a direction parallel to the longitudinal direction of the first supporting beam, and
• the second point of support is farther away from the first supporting beam than the same pipe when viewed in a direction parallel to the longitudinal direction of the second supporting beam.
