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.
