Detroit RotoStoker® VCG
The spreader stoker designed to handle a range of fuels
 The Detroit RotoStoker VCG air-cooled grate offers many of the features and benefits of the Hydrograte stoker. It is designed to provide exceptional efficiency in burning fuels ranging from coal to biomass and is ideally suited for both new and retrofit installations.
Low Setting Height:
The horizontal grate design and low setting height make it extremely attractive for installation in plants without basements.
Versatile Applications:
The grate can be cast from a variety of alloy materials. This allows our engineers to fine tune the design to the special needs of each application based on specific requirements for undergrate air temperature and fuel moisture.
Automatic Ash Discharge:
Intermittent grate vibration moves the fuel bed forward through the furnace. Ashes are automatically discharged from the forward end of the grates.
The grate is driven by the same eccentric mechanism as the Hydrograte stoker. Performance characteristics are fully-adjustable allowing the system to be optimized for specific operation conditions.
Other Benefits:
- Low installation cost. Design simplicity and delivery in large, shop-assembled modules reduces installation time and expense.
- Easy maintenance. The RotoStoker VCG grate has few moving parts and no bearings or shafts in the undergrate area to be lubricated. The undergrate area is readily accessible and castings are small, making replacement easy, should that ever become necessary.
- Effective air seals between stationary and moving surfaces allow accurate control of excess air.
