Product Profile of Travelling Grate Boiler
Thermax Babcock & Wilcox Limited brings Traveling Grate Boiler Salient Features
These shafts carry the grate chains on hardened sprockets.
Three front undergate air seals prevent air by-passing to the ash discharge end.
Grate Surface consists of a series of grate specifically designed for spreader stroke firing.
Grate curvature keeps the grate closed without the aid of auxiliary weights when making the turn around the sprockets.
Grate support within the furnace is provided by a series of skids and skidrails, each constructed of chill-hardened cast iron for maximum life.
Grate removal is easily achieved through a grate access door. On removal of one bolt, any grate section can be replaced while the stroker is in operation.
The air chamber is completely sealed both front and rear to prevent air leakage, direct and distributes combustion air through the active grate surface.
The rear seal is designed to allow rear wall expansion while maintaining tightness.
Catenary Design provides for atomic take-up or tensioning of grate chains to prevent jamming. Effective catenary is maintained by gravity, thus making external shaft adjustment.
