Replace tangent tube designs with complete membrane construction. No more hot gas bypass through the boiler casing.
Replace refractory walls with water cooled headered membrane walls. Creates a cooler furnace which reduces the formation of NOx
emissions. No more refractory walls to repair or replace.
Furnace is completely seal welded. Eliminates seal problems between refractory walls and boiler tubes.
Replace old furnace division wall tangent tubes with complete membrane construction. Eliminates hot gas bypass through warped
tangent tubes and lowers CO emission levels.
Replace refractory drum seals with welded scallop seals. Again, this prevents eventual hot gas bypass through cracked refractory
seals maintaining the low CO emission levels of todays burners.
Replacing old refractory walls and refractory seals with 100% water cooled membrane construction also eliminates the on-going maintenance
costs and unscheduled downtime associated with the older designs. These modifications also allow for quicker starter and shutdown cycles..
