Regulator For the Cooling Air Inflow of a Cooling Grate

A device for regulating a flow cross section in cooling air inflows of a bulk material grate cooler for cooling a hot bulk material carried on a cooling grate, comprising:

• a regulator housing comprising a casing formed of solid material integrated into the cooling air inflow below the cooling grate,
• an actuating member comprising a hose sleeve formed of elastic material tension-mounted at both ends coaxially in the casing and arranged to move in such a way that a rise in a flow velocity in a region of the actuating member brings about a reduction in a free flow cross section of the cooling air inflow, and vice versa, and
• a pressure difference inside and outside the hose sleeve and a deformation resistance of the sleeve being set such that the hose sleeve is deformable from its maximum flow cross section into its minimum flow cross section by the pressure difference.

A device for regulating a flow cross section in a cooling air inflow of a bulk material grate cooler for cooling a hot bulk material carried on a cooling grate, comprising:

• a regulator housing comprising a casing formed of solid material positioned in the cooling air inflow below the cooling grate,
• an actuating member comprising a hose sleeve formed of elastic material mounted at both ends in the casing and arranged to move such that a rise in a flow velocity in a region of the actuating member results in a reduction in a free flow cross section of the cooling air inflow, and
• a pressure difference inside and outside the hose sleeve and a deformation resistance of the sleeve being set such that the hose sleeve is deformable from a maximum flow cross section to a minimum flow cross section by the pressure difference.

The regulator as claimed in claim 1 8,wherein a regulating characteristic curve of the regulator can be varied by a change in a pressure of the pressure medium in the inner space of the hose sleeve.
