A heat exchanger core includes: a first passage row which is formed by a plurality of first passages; a plurality of first dividing walls separating the plurality of first passages from each other; a second passage row which is disposed adjacent to the first passage row and is formed by a plurality of second passages; a plurality of second dividing walls separating the plurality of second passages from each other; and a partition wall located between the first passage row and the second passage row, and separating the plurality of first passages and the plurality of second passages. (a) The partition wall has a greater section modulus in an orthogonal direction than either the first dividing wall or the second partition, or (b) a constituent material of the partition wall has a greater breaking strength than a constituent material of either the first dividing wall or the second dividing wall.

A cooling channel structure including a first wall section extending along a first direction, a second wall section disposed at an interval from the first wall section in a second direction orthogonal to the first direction, and a plurality of partition wall sections connecting the first wall section and the second wall section so as to form at least one cooling channel between the first wall section and the second wall section. The cooling channel having a plurality of channel cross-sections disposed at intervals in the first direction. In a cross-section including the first direction and the second direction, the first wall section includes a thin portion having a thickness smaller than a thickness tof the first wall section at a position away from each of the partition wall sections in the first direction.

Provided is a pressurizing system which includes: a pressurizing nozzle configured to supply a pressurizing gas into a hopper () where pulverized coal is accumulated; a filter configured to face a space in the hopper () where the pulverized coal is accumulated, and to allow the pressurizing gas to pass through the filter, the filter being provided at an end of the pressurizing nozzle; buffer tanks (), () in which a pressurizing gas to be supplied to the hopper () is collected at a first predetermined pressure; and a pressure control means configured to start, at a time of starting pressurization of the hopper (), supply of a pressurizing gas at a second predetermined pressure which is lower than the first predetermined pressure of the pressurizing gas collected in the buffer tanks (), ().

Downstream fitting parts of exhaust manifold branch pipes which fit into a manifold container each has a sector or fan-like cross section which is formed so that the cross-section area of the downstream end of each of the branch pipes is substantially equal to that of the corresponding upstream end. During manufacture, the downstream ends of each pipe member are expanded by a predetermined amount and then shaped to have the fan or sector-like shaped cross section. This maintains the cross-sectional area of the shaped portions substantially equal to the original cross-sectional areas and therefore the cross-sectional area of the upstream ends.
