Slag trap(big)
The large slag baffle is a slag-blocking part on a flake-type chain grate. It stops slag lumps at the slag discharge point, and the large size matches a wider grate surface.
Form and fitting position
The large slag baffle is a plate with folded edges or stiffening ribs, bolted to the grate frame at the slag discharge end and kept at a set clearance from the running grate surface. Plate width and fixing-hole positions follow the original machine dimensions, and assembly follows the original hole spacing so that the part does not interfere with the chain or the grate bars. Along with the side seals and liners, it belongs to the fixed parts at the sides and ends of the grate and is usually checked together with them during maintenance.
Material and temperature resistance
The slag baffle sits permanently on the hot slag side, so its material can be chosen from grades between HT200 and RTCr16 according to the working conditions, with temperature resistance ranging from 480℃ to 900℃.
| Material | Temperature resistance | Suitable fuel |
|---|---|---|
| HT200 | 480℃ | Low-calorific-value coal |
| HT250 | 520℃ | Low-calorific-value coal |
| RTCr | 550℃ | Low-calorific-value coal |
| RTCr2 | 600℃ | High-calorific-value coal, biomass |
| RTCr5 | 700℃ | High-calorific-value coal, biomass |
| RTCr16 | 900℃ | All types of high-calorific-value coal, biomass |
How we supply
The partner factory handles dispatch, and we can supply the large slag baffle to drawings or to the dimensions of the old part, matched together with flake grate bars, chains, pins and other parts. Material can be made to customer requirements, and we can provide selection advice and a list of matching parts. All parts are machined to OEM dimensions and tolerances.
