However, O/OE requested confirmation how to ensure that no undue ash accumulation on the burn-out grate can occur. According to the verbal information from GE, the burn-our grate is designed for a load of approximately 70t, which is quite close to the 100t (plus potentially additional loads from the transition hopper), so the load may come close to the allowed. SEPCOIII and GE shall explain how to avoid that the burn-out grate is getting ripped off from undue loading.
