The vibrating grate is one of few grates able to effectively accommodate mixtures of woody and herbaceous biomass fuel. The watercooled vibrating grate is one of the most reliable combustion grates in the world. The vibration inhibits the formation of large slag particles, which are common in straw and waste wood fuels. This makes the grate suitable for burning fuels with high slagging and ...
Travelling Grate Stoker
Travelling Grate Boiler( chain grate stoker)travelling . · This travelling chains grates stoker( this travelling grate combustiom stoker is for coal or biomass fuels) is a new style travelling grate, characterizing easier to maintain and repair . because it is no need stopping the boiler to replace the broken grate bars; it will reduce the coal leak from grate stoker
TECHNICAL PUBLICATION
Fuel is burned in today's stokers on mechanical traveling, reciproing or water/air cooled vibrating grates. Fuel is introduced on the grate through multiple fuel delivery chutes on one side of the boiler using a mechanical or pneumatic system. The pneumatic fuel distributor design allows for side and depth distribution adjustments. This is achieved by controlling the air pressure, air ...

Among the products offered by The Boiler Heater Group are AFBC boilers, . In special appliions even pinhole grates ...
Traveling Grate Sinter Plant
The Outotec traveling grate sintering process begins with the preparation of a raw mix of iron ores, fluxes, inplant dust and spillage fines, solid fuel, and return fines. Water is added to the raw mix to obtain optimum permeability for lower electricity consumption, maintained by conveying the raw mix carefully onto the sinter machine. Its surface is then ignited, air is induced through the ...
Industrial Watertube Boilers
The John Thompson vibrating grate was developed for the combustion of biomass and other low ash solid fuels with up to 50% moisture content. Either air or watercooled, the grate surface is intermittently vibrated with the use of an eccentric drive and a leaf spring mounting arrangement to induce continuous movement of the fuel bed towards the ash discharge end.
