Grate combustion is divided into chain grate, reciprocating grate, vibrating grate, and so on. The chain grate boilers are now less used because the fuel is hard to burn out, resulting from the uneven fuel layer and air distribution. Among the different types of grates, vibrating grates may have the longest life and highest availability.

Furnace with water cooled vibrant grate with dry ash extraction system. Range power 500 kW to 5000 kW. Main advantages Low horizontal dimensions Enlarged burning of various biomass types Ideal for waste burning with medium / low ash content. Other features:
With the techniques based on grates (such as inclined grate, traveling grate, chain grate and vibrating grate), the fuel is usually fed automatically onto the grate by gravity. As the fuel bed moves, moisture is driven off initially, followed by ignition, burning and finally cooling when the ash is removed.
— Water Cooled Vibrating Grate is used in various applications such as Biomass Boiler, Waste Incineration Boiler and others. In Biomass Boilers, it helps in efficiently burning biomass materials.
The Water Cooled Vibrating Grate is a well-established grate system that provides an intermittent vibration for conveying and distributing fuel evenly, and continuous discharge of fuel ash. It is particularly suited to biomass …
With the help of windswept spout feeders, the fuel on a vibrating grate can be distributed evenly over the entire grate. Windsor's go-to vibrating grate combustion system includes a water loop circuit to help regulate the temperatures of the grate. The water from the grate is independent of the boiler circuit, with the grate water cooled by ...
