Bagasse-fired boilers, natural gas backup, and ash handling systems provide reliable steam for every station.
The St. Martin steam plant features three 1,500 hp boilers (two with incline pinhole grates for bagasse and one Detroit stoker), one 1,300 hp boiler with incline pinhole grates, and two 800 hp horseshoe-furnace boilers.
Each boiler includes induced-draft fans, fly-ash removal linked to individual scrubbers, and air pre-heaters. All units can switch to natural gas when required.
Ash removal relies on screw conveyors beneath the floor feeding slat conveyors that deliver material to a centralized gathering tank outside the boiler room.
