TTNA Traveling Grate Stoker

TTNA Reciprocating Grate

TRAVELING GRATE STOKER

The Traveling Grate is a continuous ash discharge stoker with over feed arrangement. The overfeed arrangement can be either spreader or gravity feed. TTNA traveling grates are designed to burn a wide range of fuels. High moisture biomass fuels and coals of all ranks can be efficiently burned on traveling grates. The main construction feature is BAR AND KEY and uses the catenary formed by return side of the grate to maintain grate tension on the top side.

RECIPROCATING GRATE

Reciprocating Grate is a continuous ash discharge and over feed type stoker, complete with hydraulic power pack. Reciprocating grate is suitable for all types of fibrous / granular biomass fuels. The Reciprocating Grate consists of Cast Iron bars mounted on shafts. Alternate shafts are connected together and actuated by a hydraulic drive to achieve reciprocating action. There is one fixed shaft by the side of each oscillating shaft. The stroke length can be varied by adjusting the limit positions of hydraulic direction control valve and the speed of oscillation by adjusting the flow control valve.


TTNA Dumping Grate TTNA Fluidized Bed Combustor
DUMPING GRATE

Dumping grate is an intermittent ash discharge and over feed type stoker, complete with operating levers for dumping operation. Dumping Grate is suitable for low ash biomass fuels. Dumping Grate consists of grate keys assembled together to form the grate surface. The grate assembly is split into suitable number of sections in order to ensure that boiler load reduction does not occur, when one section is dumped.
