AI Technical Summary
Technical Problem
Conventional grate bars in combustion plants experience significant pressure loss and require high-power cooling water pumps due to long, complex cooling pipe paths with bends and curves, leading to high operational costs and maintenance needs.
Method used
A grate bar design with integrated cooling pipes arranged in parallel configurations, including inlet and outlet distributors and collectors, reduces pressure loss by optimizing the flow path, allowing for reduced pumping capacity and efficient heat dissipation.
Benefits of technology
The new design minimizes pressure loss and reduces the need for high-power pumps, lowering operational costs and maintenance requirements while maintaining effective cooling of grate bars.

Abstract
The invention relates to a grate bar (100) for combustion systems, comprising a substantially closed surface facing the combustion side, a rear support region which is designed to be supported on a grate support, a front nose region which runs between the surface and the front edge and which comprises a support region formed on the lower face, and a grate cooling tube system (102) which is integrated in the grate bar (100) for conducting a cooling liquid, wherein the grate cooling tube system (102) has an inlet distributor (104) for supplying the cooling liquid, an outlet collector (114) for discharging the cooling liquid, and multiple cooling tubes (108', 108", 112', 112"), each of which is individually connected to the inlet distributor (104) and the outlet collector (114) in a fluid-tight manner.
