Travelling Grate or chain grate Stoker Boiler. In Travelling Grate boiler coal is fed at one end of a moving steel chain grate. As grate moves along the length of the boiler furnace, the coal burns before dropping off at the end as ash.View More

The grate, which forms a "floor" in the furnace, is an AET BioGrate travelling grate. The continuously-moving grate carpet slowly transports the burning fuel layer towards the boiler front where the ash falls into the ash pit. The grate speed can be adjusted to account for variations in fuel quality and ash content.View More

Incineration is the most popular waste treatment method that transforms waste materials into useful energy. The incineration process converts waste into ash, flue gas, and heat. The type of thermal WTE technology most commonly used worldwide for municipal solid waste is the moving grate incineration. These moving grate incinerators are even sometimes referred to as as the Municipal Solid Waste …View More
From the feed hopper and chute the ram feeder doses the waste onto the grate in a controlled way. The grate is composed of individual grate modules with alternating fixed and moving grate block rows. The hydraulically-driven moving grate blocks stoke the waste and convey it through the combustion chamber as needed to achieve optimum burn-out.View More
The principle of horizontal feed burners is similar to that of underfeed burners. The fuel is introduced into the combustion chamber from the side (with or without a grate). During combustion the fuel is moved or pushed horizontally from the feeding zone to the other side of the pusher plate or the grate.View More
Stoker mechanism The movable fire grates move back and forth to feed waste downstream on the stokers. The back-and-forth motion of the fire grates serves to mix the waste and bring it into efficient contact with air, facilitating good combustion.View More
Coarser, heavier fuel is spread evenly on the grate forming a thin, fast-burning fuel bed. The combination of suspension and bed burning makes this method of firing extremely responsive to load demand. RELIABILITY UNDER VARYING LOAD CONDITIONS: Combines advanced spreader stoker technology with automatic ash discharge and water-cooled gratesView More
The Detroit® RotoGrate Stoker is a continuous ash discharge, traveling grate, spreader stoker that is perfect for a broad range of applications. It is recognized worldwide for its efficiency in generating steam and power. Suited for Many Applications: Biomass and waste fuels; Low ash poultry litter to high ash coal; Continuous Ash Discharge:View More
Jan 20, 2018 · In the spreader stoker arrangement, a high-speed rotor throws the coal into the furnace over a moving grate, to promote fuel distribution. Such boilers have commonly used in sizes equivalent to 10-25 MWe, but emissions control tends to be uneconomic from such units, apart from the use of cyclones for particulates removal.View More
Grate Stokers The most common type of biomass boiler is based on a grate to support a bed of fuel and to mix a controlled amount of combustion air, which often enters from beneath the grate. Biomass fuel is added at one end of the grate and is burned in a fuel bed which moves progressively down the grate, either via gravity or with mechanical assistance, to an ash removal system at the other end.View More
The DZH series moving grate boiler is wide adoptability of different fuels, it can burn different coal and biomass fuel, including wood chips (long wood less than 2m could burn without broken). Except wood fuel, it could also burn bagasse, staw, waste cloth, rice husk, etc.View More

The primary air is fed underneath the grate, transported into three or four sealed-off primary air zones and finally through the grate bar perforations into the primary combustion chamber of the furnace.View More
The most flexible, but also the most expensive type of system, the moving grate – sometimes called inclined or step-grate – requires considerable combustion space and additional equipment. The fuel is shuffled into the combustion chamber using stepped grates, which cause the fuel to …View More
This hostile environment demands a material that can perform at elevated temperatures and conditions of high abrasion. In addition to the running gear, the related grate castings are also available. Engineered steel versions are also available such as the Thompson moving grate or stoker chains.View More

When the fire has been reestablished on the dumped section, the process is repeated on the other sections. 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.View More
