AI Technical Summary

Technical Problem

The grate blocks of an incinerator are easily affected by heat load in a high-temperature environment, leading to corrosion and a shortened service life. In addition, the air supply channel is easily blocked by incinerated materials and liquids, affecting cooling and incineration efficiency.

Method used

Design a grate block including an air supply channel with the air inlet on the upper wall surrounded by a thickened part. The thickened part prevents liquid from flowing into the air inlet, reducing the risk of blockage. The optimized air supply channel design ensures efficient cooling and complete combustion of incinerator materials.

Benefits of technology

It effectively reduces the risk of air supply channel blockage, improves the service life and combustion efficiency of grate blocks, and reduces maintenance costs.

Abstract

The invention relates to a grate block (10) for a grate of an incinerator. The grate block (10) comprises a block body (12) having an upper wall (14) forming a support surface (16) along which incineration material is to be conveyed, and a front wall (20) having a support edge (23) designated for contact with the support surface of an adjacent grate block in a pushing direction S, wherein the upper wall (14) has an air supply opening (35) constituted by an air supply channel (38). The air supply opening (35) is at least partially surrounded by a thickening (50) protruding from the support surface (16), which forms a protection channel (57) extending the air supply channel (38) and is designated for preventing liquid from flowing into the air supply opening (35).
