B&W Volund combustion grates provide waste flow that ensures drying, ignition, combustion, energy release and complete burn-out before the bottom ash outlet. In a waste-to-energy plant, the grate is where waste is converted into energy - the heart of the system.As such, grates are a significant focus area for us. Over the past 80 years we have supplied more than 500 combustion grates worldwide.

boiler types are represented: six traveling grate stoker boilers, four water-cooled vibrating grate boilers, four bubbling fluidized bed combustors (FBCs), one circulating fluidized bed (CFB) boiler, one fixed-grate boiler, one sloping grate boiler, and two pulverized coal (PC) boilers retrofitted to cofire solid or gasified biomass.
Vibrating Grate. Vibrating grate application has been for small and medium sized spreader stoker fired boilers. A timing device creates dwell time and vibrating time changing with boiler load. Units having more than one module in width are vibrated separately rather than in unison. Refuse such as wood or bagasse is burned successfully on an air
These demands included lower excess air firing for efficiency and emission control, higher boiler capacities, and greater availability to the plant.The demands weremetin part by the air-cooled vibrating gratestokerand,moreimportantly, the newly developed watercooledautomatic ashdischarge grate.

The front room floor does feel like its vibrating but perhaps the noise I am hearing gives the suggestion of vibration (sounds like a bus engine idling in distance or the throb of engine when you are on a ferry but very low level). At night when all is quiet it's horrendous as there are no other noises to mask it. It sounds like a pump running

Dumping grate stokers have been built for boilers in the size range of 15,000 to 75,000 pounds of steam per hour. The larger coal-fired spreader stokers use continuous ash discharge grates. The most popular version of this type of grate is the traveling grate. Reciprocating grates and vibrating grates are also sold but are less popular.
